Batch Combine Images Using the Grouping Workaround

Use this workaround to bypass the mobile app's limit by creating intermediate PDFs and merging them together sequentially.

Because the mobile app restricts you to 12 images per action, you can overcome this limitation by processing your images in smaller chunks. By creating multiple intermediate PDF files, you can merge those PDFs together into a single master document.

1
Select the first batch of images

Open your mobile application, select the first 12 images from your gallery, and combine them into a single PDF file. Save this file with a recognizable name.

2
Repeat for remaining images

Continue creating 12-page PDF files for the rest of your images until all the pictures have been converted into individual PDF documents.

3
Combine the intermediate PDFs

Use the 'Combine Files' feature in the app to select all the newly created PDF files and merge them together into one large, final PDF document.

Frequently Asked Questions

Why do some mobile PDF apps limit image selection to 12 files?

Can I combine more than 12 images using desktop PDF software?

Yes, desktop versions of premium PDF editors generally do not impose strict image limits, allowing you to select and combine a massive number of files at once using a computer's higher processing capacity.

Are there dedicated apps that combine large batches of images into a PDF for free?

Yes, comprehensive office suites like WPS Office have built-in Image-to-PDF converters that allow you to merge significantly more images into a single PDF document natively and for free.
