Reduce a PDF's size for email
Short answer
Too big to email? Shrink your PDF in the browser — nothing uploaded. Email limits sit near 20–25 MB; this strips redundant data to get you under.

Runs in your browser — your file is never uploaded.
Most email providers cap attachments near 20–25 MB. A quick lossless pass often trims a bloated export enough to send. If a PDF is huge because of high-resolution scanned images, expect smaller gains from a lossless pass — the data itself is large.
The whole thing runs on your device, so a confidential attachment is never uploaded just to shrink it.
