How do I reduce PDF size for email?

Drop a PDF, upload it, then continue to download the compressed file. If it’s still too large, compress again or export images at lower quality first.

What attachment size limits do emails have?

Limits vary by provider. Gmail allows up to 25MB total per email, and many corporate systems enforce smaller limits such as 10MB or less.

Will compression reduce quality?

Compression reduces file size by optimizing content. Results depend on your original PDF — review the output before sending.

Reduce PDF size for email

If your PDF won’t attach to an email, it’s usually because the file is too large. Use PDFOperations to compress your PDF so it can be sent via Gmail, Outlook and corporate email systems. For strict portals, you may also need a specific cap like under 10MB or under 5MB.

Gmail & Outlook

If the attachment fails, compress first. Gmail is more generous, corporate systems often aren’t.

Image-heavy PDFs

Scans and embedded images inflate file size fast. Compression reduces weight dramatically.

Straight upload → download flow. See Privacy for retention and deletion details.
