PDF file turned blank after we edited and saved in Flies

After I let my student write down his answers in the questionnaire PDF file on my Ipad, we closed the file and I saved it in the default File app. A few minutes later I opened the fIle again and I found out all pages have turned blank, except the pages that my student put notes on. But all contents are gone, except his notes. Please help!!

I lost all my mark up on a pdf ! writing this post with complete frustration. I used my ipad mini 6 yesterday to do a homework on a PDF. I spent the whole morning marking on the Pdf opened by the File app pre-installed with Apple device. Today when I was about to submit the homework I found all the markups are gone ! Gone! All the notes markups! no where. reopened the file several times and waited for a while. still not coming up! I tried to open the file with other apps such as pdf reader and nothing preserves. I searched for the same issues in the community but found no answer useful. Now do have to mark up all again? It's very annoying considering all the time and effort i spent on the markups. I can't believe ipad mini was such an unreilable device since the primary purpose that i bought it for was writing on it and study. Again totally disaopointed.

PDF damaged or corrupted I have been writing notes on a pdf-book using pencil on my iPad. Used to open pdfs in default pdf viewer. Today when I was scrolling the pdf the file closed automatically and now its not opening. The size also got reduced to 17 mb from more than 1.5 gb (it was a 950 page book). Also in the iCloud it got synced and I'm seeing the same corrupted / damaged file! Is there a way to recover the file, I have my exams really soon and all my notes are gone. Please help Apple iPad Air (5th gen)

Pdf Files disappearing after iPadOS 17.2 update The night when my iPad updated automatically at least 10 (random) pdf files, that were saved on my iPad disappeared. I could see them in recent folder, but when i opened them it was black screen. I couldnt move them, share, rename etc. altough the file had the information when it was last edited. I contacted apple support and they couldn’t do anything about it, except suggested that in the future I save my files in iCloud drive. So I did that, re-did all the notes for my exam (that is in a week). Today, when I was editing on my ipad, the file that I was using was not opening again (like the previous time), only this time I could share/rename/delete it, but still it was black and couldn’t open on any device. So i started editing the file copy directly in iCloud drive and it disappeared as well… like on my iPad. Has anyone else experiences this after the update? Did you manage to solve it??? My exam is in a week and all my notes (summary of 600 page book) are gone… help

Hi CedricNguyen,

Wondering which iPadOS version you are using on your iPad.

Apple support has an article online:

(Eg: In iOS 16)Seems PDF files are now kept and read in the Book app.

For accurate info: Choose your iPad OD version at the top of the articles below:

Read PDF documents in Books on iPad – Apple Support

and

Save and edit PDFs to the Books app on your iPhone or iPad - Apple Support

All the best :-)

Thank you, CedricNguyen, for your reply, and added info!

Re: the pdf is blank again after I edited

About iPadOS 16 Updates - Apple Support

says: the most recent is PadOS 16.3.1

May be good to update and see if there's any improvement.

(If you do have that version already:

maybe try re-starting your iPad: Restart your iPad - Apple Support

(ie: If something is not working right, restarting will often put things back in order.)

Re: the pdf is blank again after I edited

Wondering how you are editing the original PDF

Eg : in Read PDF documents in Books on iPad – Apple Support

says: Mark up a PDF:

Open the PDF and tap to use the drawing and annotation tools

(tap near the center of a page if you don’t see ).

If needed:

Re: does the heavy file have impact on this? Because my pdf file is 293mb

That is a hefty file! Sorry, I don't know for sure.

(Wouldn't think so, as the Books app handles and annotates books.)

Wondering how you are saving the file after editing.

Seems Apple is now often using the "Share" button to export / save files in apps
