Send a big PDF by email
Most email stops attachments at around 20–25 MB: Gmail at 25 MB, Outlook at 20 MB. If your PDF is bigger, compress it first; if it’s still too big, split it or send a link.
1. Compress it
Preview: File → Export → Quartz Filter “Reduce File Size” (free; sometimes blurry or bigger). Whizra: select it and type compress it for email
, which picks a strong setting, or compress my last pdf under 2 mb
.
2. Split it
Send it in parts: Whizra splits a PDF by pages (split a PDF).
3. Send a link
A cloud drive link sends any size, but that uploads the file to the cloud drive.
