Compress PDF for Email
"Message exceeds the size limit" — the bounce nobody has time for. Compress the attachment to email-safe size and it arrives: every server, every inbox, every forward. We compress toward your target at the best quality that fits, never make the file larger than the original, and always show the real final size — very image-heavy files may land slightly above tight targets.

Email's real limits
Advertised limits (25MB) mislead: corporate servers cap lower, encoding inflates attachments ~35% in transit, and recipient mailboxes have quotas. Practically, attachments under ~5MB always arrive; under 2MB they arrive politely.
Etiquette is part of it
A 20MB attachment hogs the recipient's quota and sync bandwidth for no reason a compressed file would not serve. Sending small is simply professional — and takes one compression pass.
