Markup in Files on iPadOS corrupting PDFs

Hi Community,

I’ve been using Markup to annotate PDFs on iPadOS for a few months now and have experienced several instances of corruptions of PDFs (i.e. Files, Books, nor Adobe Acrobat are able to open the PDF). After the file has been corrupted, the file thumbnail in files just shows the text ‘pdf’ in blue.

im not doing anything crazy - just scribbling annotations on the PDFs using Apple Pencil.

I’m currently running iPadOS 17.3 on an iPad Pro (11-inch) (3rd generation), but I also experienced this issue on the same iPad when running iPadOS 17.2 prior to updating.

On the first occasion I lost 1 month of edits!!! After this I began duplicating files throughout the day to minimize data loss should this happen again..

it happened again this morning and I lost 4 hours of edits, so decided to raise the issue.

Has anyone else experienced this?

My recommendation - Do NOT use Markup in Files on iPadOS For critical work until this is fixed by Apple.

I have the same experience. I didn’t do anything suspicious. I just edited the files as usual, then suddenly one day after editing, the file went corrupted. So sad at that moment because it took me 1 month to go from just a few MB to nearly 1GB. I called Apple Support with the only purpose is to find solution to recover the file. But no helpful solution is given. I accepted the fact that I lost the file. So disappointed because i had just bought an iPad recently just to note everything for my studying, but if the files keeps corrupting like this, i don’t know what i buy an iPad for.
