In the latest version of Adobe Acrobat Pro, attempting to combine multiple JPG files of varying pixel dimensions and DPI into a single PDF causes the application to close abruptly without any error message. This occurs consistently when at least one image in the batch differs significantly in resolution or aspect ratio from the others.

Steps to Reproduce:

Open Acrobat Pro (latest build).

Go to File → Create → Combine Files into a Single PDF.

Add multiple JPG images with different dimensions/DPI (e.g., mix of 300 DPI A4‑sized scans and smaller 72 DPI images).

Click Combine.

Expected Result:Acrobat should successfully create a single PDF containing all images, scaling them as needed.

Actual Result:The application closes instantly without any error dialog or crash report prompt. The PDF is not created.

Additional Notes:

Issue does not occur when all images share the same dimensions/DPI.

The crash occurs regardless of whether images are added via drag‑and‑drop or the “Add Files” dialog.

Workarounds include pre‑normalizing images to the same size/DPI or converting them to PDFs in smaller batches before merging.
