PDF too large for Gmail?
Gmail blocks attachments over 25 MB and quietly converts larger files to Drive links — which many recipients can't open without signing in. The fastest fix is to compress the PDF below the limit and attach it normally.
Why this works
This page runs the same compressor as our main tool but with a Gmail-tuned target: under 24 MB to stay safely below the 25 MB ceiling and account for MIME-encoding overhead.

Common questions
Why does Gmail say my 24 MB file is too big?
MIME encoding adds about 33% overhead. Aim for 20 MB or less if you keep hitting the limit.
What if my file is over 100 MB?
Split it first using our Split tool, then compress each piece individually.
