Cannot combine mutiple image files into a single PDF

Question

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:

Acrobat checks security setting for the files.
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?"
If I open the combined file, I can always insert the file marked as problematic and create a PDF.
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.

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.
