So I've been marking up a large pdf for some time and after having saved and closed it the last time, the icon no longer displays the first-page image anymore and won't open in Preview (or Adobe Acrobat Reader), generating the message "It may be damaged or use a file format that Preview doesn’t recognize."
I copied and pasted text into a note box on the file which I think is being treated as unsupported, even though the text is from the document itself.
The only recovery tool I know of that I've had success with in past is this - https://www.pdf-online.com/osa/repair.aspx - but it has a limit of 32mb and mine is over 40mb. Is there anything else I can do to "repair" it?
Thanks
