Impossible to use Acrobat Reader with heavy files

[BrunoSouth]

Hi. I am switching to Wondershare to use PDF since Acrobat can not handle files with architectural layouts. It lags and crashes. Do you find the same problem with PDFs that are bigger than the "average" document file?  

Thank you

Hi @Bruno_s,

Thank you so much for taking the time to share this feedback — and really sorry to hear about the frustrating experience you’re having with large files in Acrobat Reader. We completely understand how disruptive it can be when an essential tool becomes unstable, especially when you’re working with heavier documents. Please confirm whether you are using Acrobat Pro or Acrobat Reader.

We’d love to investigate this further and work toward a resolution. To help us do that, could you please share the following details:

If you’re comfortable, please upload the PDF file that’s triggering the issue (or a similar large file if it contains sensitive content).

Screen recording — A short video showing how the lag or crash occurs would help us see the behavior more clearly.

Crash logs or diagnostic logs –

On Windows:

• Open Reader > Help > Troubleshooting > Generate System Report

• Or check Event Viewer for recent crash entries under Windows Logs > Application (look for Acrobat-related errors)

On macOS:

• Go to https://adobe.ly/3GL0ecX > User Reports or Crash Reports and look for recent Acrobat Reader entries.

Steps to reproduce – Let us know:

• When does the crash or lag happen? (e.g., on scroll, zoom, search, page navigation?)

• Does it happen with all large files or just specific ones?

• What version of Reader are you using? (Help > About Acrobat Reader)

In case the above steps don't help collect diagnostic or crash logs, please use the following steps:

To collect the logs:

1. Download and run the Diagnostics Utility from:  https://adobe.ly/4o824VW
2. Click on Start Diagnostics. Ensure advanced logging is checked.
3. Launch Acrobat, reproduce the issue with your file.
4. Once done, click Stop Monitoring.
5. Copy the Log ID and share it with us.

For a crash or freezing issue, we would require crash logs: https://adobe.ly/456WhqR

• Upload logs to any Cloud Drive(OneDrive, Google Drive, Dropbox, etc)

Best regards,
Tariq | Adobe Community Team

Okay, I have read all I need to do, and I would rather use Wondershare. I just wanted to let you know Acrobat doesn't handle significant documents well. I would love to share the file with you, but it is a private project for different corporations, and the documentation isn't for sharing.
