Email attachment questions
What size should an email PDF be?
Many mailboxes reject attachments around 20–25 MB, and some are stricter. Compress until the file attaches. If it is still too large, send a cloud link instead of squeezing the text until it breaks.
Does compressing remove pages?
No. The page count stays the same. Compressing reduces image weight inside the PDF so the file takes less space.
