Compress PDF for Email — Gmail, Outlook & HR Limits

Mailbox and recruiter portals reject oversized PDFs long before you notice on disk. Compress with a quality check, then attach once. Gmail’s headline attachment limit is larger than many recruiter and government forms, which still cap uploads at 2–5 MB. Corporate gateways can be stricter than consumer mail.

Limits are not always 25 MB

Gmail’s headline attachment limit is larger than many recruiter and government forms, which still cap uploads at 2–5 MB. Corporate gateways can be stricter than consumer mail.

Compress, then attach

Use Compress PDF with Basic for contracts and forms. Preview footnotes and stamps, then attach the optimized download — not the original scan.

Merge first when you have many files

If you planned five attachments, Merge PDF into one ordered file, then compress that single PDF so recipients do not miss page two.
