Hi @ed_6516,    Thank you for raising this concern. We understand how frustrating it is when embedded videos don’t play as expected. Here’s what you need to know and do: 1. Supported Formats Ensure your video is MP4 (H.264) or MOV with AAC audio. Acrobat only supports these formats for embedded playback. 2. Install Required Codecs - important Verify that H.264 codecs are installed on your system. Without them, the video may not render even if the audio plays. 3. Check Multimedia Preferences Go to Edit > Preferences > Multimedia (Legacy). Confirm the correct player option (QuickTime or Windows Media) is selected for legacy content.   4. Adjust Trust Settings Navigate to Preferences > Multimedia Trust (Legacy). Enable “Allow multimedia operations” for trusted documents.   5. Security Mode If playback still fails, temporarily disable Protected Mode under Preferences > Security (Enhanced) for testing. Re-enable after confirming.   6. Platform Limitation Embedded videos only play in Acrobat desktop (Reader or Pro). Due to viewer restrictions, they won’t work in browsers or mobile apps.   You can check this help page as well: https://adobe.ly/48KlR8G   If you’ve tried these steps and the issue persists, please share: Acrobat version and OS details. A sample PDF. A short video of the issue and Acrobat diagnostic logs (via Help > Collect Logs). If you can't see the option, launch Acrobat > Help > Preferences  Mac > Acrobat Preference.

Thank you all for sharing your experiences and frustrations. We understand how disruptive this issue can be, especially when managing large PDFs. This error — “One or more pages are in use and could not be deleted” — often occurs due to internal locking or accessibility processes. While we continue to investigate the root cause, here are some workarounds that have helped many users:   Possible Solutions   1. Update Acrobat Ensure you’re on the latest version via Help > Check for Updates.   2. Disable Assistive Technology Support Go to Edit > Preferences > Accessibility and uncheck Enable assistive technology support.   3. Try Alternative Delete Methods Navigate to a different page, then use Edit > Delete Pages and enter the page number manually. Use Replace Pages instead of Delete if the error persists.   4. Close Preview Panes and External Locks If the file is open elsewhere (including Explorer preview or Citrix sessions), close those windows before deleting.   5. Save As New Copy Sometimes saving the file under a new name clears the lock and allows deletion.   We acknowledge this has been a long-standing pain point for some workflows, and your feedback is critical in helping us prioritise in triaging this issue. To help us diagnose further, could you please share: Acrobat diagnostic logs (via Help > Adobe Acrobat > Collect Logs) If you can't see the option, launch Acrobat > Help > Preferences  Mac > Acrobat Preference. General > Enable Troubleshooting, Click Ok.  Try again.

Hi @henry_5403,    Thanks for reaching out. I am not sure what the question is here. If you have the paid version, you can open the form in Adobe Reader or Acrobat. Fill it out and save it as a PDF so you can retain the original copy. And it goes to the next person, who can also use Adobe Reader to complete or sign it.  Alternatively, you can use Acrobat Sign if you have an Acrobat subscription.

Hi @cb4232021,  Thanks for reaching out.  The “Enable right-to-left language options” setting in Acrobat preferences allows the application to properly support languages that are written from right to left, such as Arabic, Hebrew, or Persian semantic language support. Here’s what it means in practice: Text Direction: It enables correct text flow for right-to-left scripts in comments, form fields, and editing tools. UI Adjustments: Some interface elements (like alignment options) adapt to accommodate right-to-left reading order. Document Handling: This option ensures proper display and editing behaviour when working with PDFs that contain right-to-left content. What kind of Form you have it is XFA form?  Best regards, Tariq | Adobe Community Team ... View more

Hi @Willie31310290j7hr,      We are truly sorry to hear about the time and effort you lost while working on Adobe Acrobat Online.   Spending hours adding comments only to lose them is incredibly frustrating, and we completely understand how disruptive this can be. Your feedback is important because it highlights a critical issue that can impact productivity. We appreciate you sharing the details. It helps us identify areas where the experience needs improvement.   To assist us in identifying the root cause of the issue, could you answer the following questions: Which application and version are you using (e.g., Adobe Acrobat Online, desktop, Chrome)? Are you logged in with an Adobe account or using a guest session? Which browser and version are you using? Have you tried another browser? Was your internet connection stable during the session? Did you notice any error messages or warnings while saving or downloading? Other than loading. Did it happen today or during the AWS outage, a couple of days ago? How were you adding comments—sticky notes, highlights, or text annotations? Did you save periodically or rely on autosave? Did you attempt to download before finishing all edits, or only at the end? Did you refresh or close the tab at any point before saving? What was the size and type of the PDF (scanned image, text-based, form)? Was the file uploaded from local storage or cloud (e.g., OneDrive, Google Drive)? Did you notice any lag or freezing while editing?   Suggestions For now, to avoid similar issues, we recommend using the desktop version of Adobe Acrobat or saving work periodically. If you prefer online tools, consider downloading the file after every few edits to ensure changes are preserved.  If you still have access to the original file and if that was uploaded to Adobe Cloud storage, please share the link to the document. That will help us investigate the issue.    Best regards, Tariq | Adobe Community Team ... View more

Hi @warm_amazement2245,   Thank you for reaching out regarding the issue with adding headers and footers to your PDF document. To help us identify the root cause and resolve this quickly, please review the checklist below:   Troubleshooting Checklist Software Details  Which application and version are you using to edit the PDF? (e.g., Adobe Acrobat Pro, Acrobat Standard) Document Permissions Is the PDF password-protected or restricted from editing? If yes, please remove restrictions or share an editable version. File Behaviour Does the issue occur on all pages or only specific ones? Are you seeing any error messages or unusual behaviour when attempting to add headers/footers? Source of PDF Was the PDF created from a scan, export, or another source? If possible, please share details about how the file was generated. Reproducibility Can you try adding headers/footers to a different PDF file? If the issue occurs on multiple files, it may be related to the software or environment. Next Steps If the issue is file-specific, we recommend regenerating the PDF from the original source. If the issue persists across multiple files, please ensure your software is updated or reinstall it.   Please share your findings from the above checklist so we can assist you further.

Hi @nicolette_8882,    Thanks for reaching out.   The “bad parameter” error during batch redaction usually points to an issue with how the tool processes multiple files rather than a single-file problem. Here are some tips to resolve this:   Here’s the revised draft without checkmarks:   Troubleshooting Checklist for Batch Redaction in Acrobat If you’re seeing a “bad parameter” error when loading an entire folder for redaction, try these steps: 1. Verify Folder Contents Ensure all files are PDFs (no hidden non-PDF files). Remove files with unusual characters in names (e.g., # , % , & ). Check that none of the PDFs are password-protected or digitally signed. 2. Move Files to Local Storage Copy the folder to a local drive (avoid network or cloud paths). Ensure you have full read/write permissions. 3. Test Smaller Batches Split the folder into smaller groups (e.g., 10–20 files). Run the redaction on each batch to identify problematic files. 4. Preflight and Optimise PDFs In Acrobat, go to Tools > Print Production > Preflight. Run a basic PDF validation and fix any structural issues. Alternatively, use PDF Optimizer to clean up metadata and embedded content. 5. Update Acrobat Make sure you’re on the latest version of Acrobat. Older builds had known issues with batch redaction workflows.   Recommended Workflow for Reliable Batch Redaction Open Acrobat and select the Redact Tool. Choose Add Files instead of loading the entire folder at once. Add files in manageable batches. Apply your redaction settings and run the process. Save the output to a new folder to avoid overwriting originals.   Important Note: The batch redaction feature is sensitive to file integrity. If one file fails validation, the entire operation can throw an error. Following the above steps may help you isolate issues and ensure a smooth process.

Hi @daisy_9456,    Thanks for reaching out.  How to Fix Layout Shift When Printing PDFs 1. Check Acrobat Print Settings Open the PDF in Acrobat. Go to File > Print. Under Page Sizing & Handling, select Actual Size (not Fit or Shrink). Ensure Auto Rotate and Centre are enabled. Do not tick “Choose paper source by PDF page size” unless required. 2. Verify Printer Properties Click Printer Properties in the Print dialogue. Confirm the correct paper size (e.g., A4). Disable any “Borderless” or “Auto-centre” options that might shift content. 3. Use ‘Print as Image’ (Optional) In the Print dialogue, click Advanced. Tick Print as Image to bypass driver interpretation. 4. Check Export Settings in Exact Ensure the PDF is generated at the correct page size (A4 vs Letter). If possible, disable any scaling options during export.   Let us know how it works.

Hi @WLieske     Thank you for sharing the details of your workflow and your concern about files being deleted when using Microsoft Print to PDF. First, it is not recommended to print to PDF as it flattens the document and removes layers, fonts, and other details. I understand how unexpected and disruptive this behavior can feel, especially when the intention is simply to preserve edits.   Why this happens The “Print to PDF” option works differently from “Save As.” Instead of updating the existing file, it creates a new PDF from the print stream—similar to printing on paper. When the same filename and location are selected, the system attempts to overwrite the original file. If the overwrite process fails (due to permissions, network latency, or file locks), the original file may be replaced with a zero-byte file or appear deleted. Recommended approach Use Save As within Acrobat for edits. This ensures the original file remains intact and metadata is preserved. If you need to flatten content or standardise page sizes, consider using Print to PDF instead of Acrobat’s Preflight or PDF Optimizer tools. Avoid selecting an existing file during Print to PDF; save to a new name and then replace manually if needed. Ensure filenames do not contain special characters and that the target folder is fully accessible. Important note This behaviour is tied to how Windows and Acrobat handle virtual printing. It’s not an intended “delete” feature, but a side effect of overwrite logic. Adobe does not recommend using Print to PDF as a substitute for Save As.   Let us know if that answers your the problem.    Best regards, Tariq | Adobe Community Team ... View more

Hi @rib8192    Thank you for sharing your thoughts on streamlining the signing process. It’s clear you want a smooth experience for everyone involved, which is a great goal. When working with certified PDFs, Acrobat applies certain safeguards to maintain document integrity. These safeguards include limiting changes after certification, which is why actions like adding new signature fields or bypassing confirmation steps aren’t typically available. This approach helps ensure the document remains trustworthy for all parties.   If flexibility for multiple signers is important, one practical way forward is to prepare the necessary signature fields before certification or consider using standard digital signatures instead of certification. Both options allow you to keep the signing process efficient while still maintaining security.   One option to streamline this process is to create an Acrobat Action that incorporates a JavaScript step. Actions allow you to automate tasks across documents, so you could include a script that: Validates required fields. Highlights empty fields by changing their background colour. Displays an alert listing missing fields. This approach helps reduce manual steps and keeps the workflow efficient. Disclaimer: Adobe does not provide official support for custom scripting or Action development. Any scripts you create are implemented at your own discretion, and it’s recommended to test thoroughly before deploying in production. Best regards, Tariq | Adobe Community Team ... View more

Hello,    Yes, you can highlight the empty fields by changing their background colour dynamically in your validation script. Acrobat JavaScript allows you to modify field properties such as fillColor . Here’s how you can extend your existing code:   var emptyFields = []; for (var i = 0; i < this.numFields; i++) { var f = this.getField(this.getNthFieldName(i)); if (f.type != "button" && f.required) { if (f.valueAsString == f.defaultValue) { emptyFields.push(https://adobe.ly/475LiQZ); // Change background colour to light yellow for empty fields f.fillColor = color.yellow; } else { // Reset colour for filled fields f.fillColor = color.white; } } } if (emptyFields.length > 0) { app.alert({ cMsg: "Incomplete! Missing fields:\n" + emptyFields.join("\n"), nIcon: 1 }); } else { app.alert({ cMsg: "All is good", nIcon: 4 }); } Key Points: f.fillColor sets the background colour of the field. Use predefined colour constants like https://adobe.ly/47dRTJf , color.yellow , color.white , or create custom colours with color.rgb(r,g,b) . Resetting colour for filled fields ensures the form looks normal once completed. Also, wait for more inputs from experts. Best regards, Tariq | Adobe Community Team ... View more

Hi lain,    Thanks for sharing the details. Let me clarify a few things about GPU usage in Acrobat Pro:   1. Acrobat and GPU acceleration Currently, Acrobat does not use GPU acceleration for rendering PDFs. Page rendering, including images and vector content, is done primarily via the CPU. The older versions like Acrobat X also did not rely on GPU for page display.   2. Why you might see partial rendering Acrobat sometimes displays pages in “progressive rendering”: it first draws the top portion of the page, then finishes the rest. For large images or complex pages, this can make the page look incomplete until you zoom or scroll, which forces a repaint of the page. This behavior can be influenced by page content size, memory usage, or system resources, not the GPU.   3. Settings to check Page Display Preferences → Rendering   You may try “Smooth Images” and “Enhance Thin Lines” options to see if the display improves.   4. Other tips to improve performance Reduce display resolution for images in PDFs if possible. Ensure you are on the latest Acrobat update.   Let us know how it works. Would you be willing to share a couple of files with us?  If yes, and you can't share the file publicly, upload files to any cloud drive and share the link via private message.

@pierret18811376,      The message you’re seeing — “This document contains constructions that may affect its appearance. Review it before continuing.” — is a generic alert from Acrobat. It appears when a file includes certain layered or dynamic elements (for example, form fields, transparency effects, or other structural objects) that could visually change once the document is signed.   When you apply a digital signature, Acrobat locks the file to preserve its integrity. This means the document becomes read-only, and any visual layers or interactive elements are flattened, which can slightly change how it appears. The alert simply asks you to review the document before Acrobat finalizes it to ensure everything looks correct.   After reviewing the content, you can safely continue signing. The warning doesn’t indicate a problem with your file — it’s just a precautionary check to help you confirm the document’s appearance before it’s permanently locked.   Thanks for pointing out, I have fixed the links above, and here it is again: https://adobe.ly/47a8RGQ Best regards, Tariq | Adobe Community Team ...

Hi @Blissful_Songbird5950,     Thanks for sharing the details. The behavior you described — where the Stamp Palette window no longer opens — could depend on the Acrobat version or the interface mode in use. To better understand what’s happening on your side, could you please share a short screen recording or screenshot showing what occurs when you click the Stamp Palette button?   Meanwhile, if you’re using the modern Acrobat interface, you can switch back to the classic view to check if the Stamp Palette reappears:   1. Open Acrobat. 2. Go to View (or the hamburger menu ☰) → Disable New Acrobat. 3. Restart Acrobat and try accessing the Stamp Palette again.   This will help us narrow down whether the issue is related to the interface or a specific version change.   Thanks for your patience while we sort this out!

Hi @Brenda27663925ul6y,       Thank you for detailing everything you’ve tried — that really helps narrow it down. From what you describe, the issue seems to occur only when combining or converting PNG files into PDF within Acrobat, while other formats work fine.   This behavior can sometimes occur when certain PNGs contain unsupported transparency or color profiles, or when macOS/Windows file sandboxing interferes with Acrobat’s image-handling components.   Here are a few steps you can try:     1. Batch re-save PNGs using a system tool or another app before combining: On Windows, open all PNGs in Paint and re-save as PNG (or JPG). On macOS, use Preview → Export → PNG. This refreshes the image encoding and removes transparency or metadata that might be blocking Acrobat’s processing.   2. Try the Combine Files tool directly from Acrobat’s Home screen: Open Acrobat → Tools → Combine Files Add the PNGs and combine them into a single PDF. Avoid right-click “Convert to PDF” if that’s what triggers the issue — it sometimes uses different system calls.   3. Check sandbox restrictions (Windows only): Go to Edit → Preferences → Security (Enhanced) Temporarily uncheck Enable Protected Mode at startup Restart Acrobat and try again. (If it works, re-enable protection after testing.)   4. If you’re working with bulk PNGs, you can use Adobe Bridge or a simple batch converter (like ImageMagick or IrfanView) to quickly convert them into PDFs first, then combine them using Acrobat — this avoids file-level issues.     If this persists even after re-saving the PNGs, it might be worth sharing one sample file (without sensitive info) — this helps confirm whether the image encoding is causing the conflict.
