Cannot combine mutiple image files into a single PDF

[cflnest]

Acrobat (build 2003.003.20284) running on a 64GB M1 Max Mac (macOS 12.6.1) has an issue combining multiple image files (PNG's or JPEG's) into a single PDF.  Here's what usually happens:

1. Acrobat checks security setting for the files.
2. After several minutes have elapsed, sometimes an error message appears: "There was an error encountered while combining fies. Do you want to combine the combined file or return to the file list and try again?"
3. If I open the combined file, I can always insert the file marked as problematic and create a PDF.
4. At other times the whole process hangs and I must to force quit Acrobat.

Wondering why Acrobat has to check the security settings of screenshots generated with the native macOS app on my own system—is there a way to disable this check?

Other PDF apps combine multiple files almost instantaneously on my system without error.

Try this: Go to the Acrobat app menu - Preferences - Security (Enhanced) and disable anything that's selected there, then try it again.

If you're having trouble combining multiple image files into a single PDF, I can certainly help you with that! To create a single PDF of multiple image files, you can follow these steps:

Method 1: Using Online Tools

• Go to an online image-to-PDF converter, such as Smallpdf, ILovePDF, or PDF2Go.
• Upload or drag and drop your image files onto the website.
• Arrange the images in the desired order if needed.
• Click on the option to convert or generate the PDF.
• Once the conversion is complete, you can download the combined PDF file.

Method 2: Using Software

If you prefer using software on your computer, you can use Adobe Acrobat (if you have it) or other PDF editing software like PDF-XChange Editor or Foxit PhantomPDF. Here's how:

• Download and install the PDF editing software if you don't have it already.
• Open the software and go to the option to create a new PDF.
• Choose the option to add images or insert images into the PDF.
• Select all the image files you want to add and arrange them in the desired order.
• Save the PDF with a suitable name and location.

Method 3: Using Command Line (Linux)

If you're comfortable with the command line, you can use `convert` and `convert-im6.q16` (ImageMagick) to combine images into a PDF on Linux:

• Open your terminal.
• Navigate to the directory where your images are located using the `cd` command.
• Run the following command to combine the images into a PDF:

```bash

convert image1.jpg image2.jpg image3.jpg output.pdf

```

Remember to replace `image1.jpg`, `image2.jpg`, and `image3.jpg` with your actual image file names, and `output.pdf` with the desired name for the PDF.

Once you've chosen a method and successfully combined your image files, you should have a single PDF containing all your images. If you encounter any specific errors or issues during the process, feel free to ask for further assistance.

Thanks for listing a number of methods to combine image files into a PDF.  I use PDF Expert.

The purpose of my post was to report a bug in Acrobat for a commonly used task that does not work as it should.
