PDF Compressor for Email
- Secure processing
- Automatically deleted
- No signup
- Files are uploaded privately, processed on a secure server, and not retained for later use.
- Uploaded and generated files are automatically deleted within one hour.
Use this PDF compressor for email when your attachment exceeds provider limits. Reduce file size in the browser, then attach the compressed PDF without bouncing messages.
Gmail allows roughly 25 MB per message, but many corporate gateways cap lower—aim for 5–10 MB when unsure.
If still too large, split the PDF into sections and compress each part.
Secure Server-Side
Your file is uploaded securely for temporary processing. See the tool details below for retention behavior.
How to use this tool
Upload the PDF, select a compression preset aimed at email limits, download, then attach the result.
Worked example
Example: compress a 15 MB scanned invoice packet to under 10 MB for a Gmail attachment before sending to a client.
When to use this
- Gmail or Outlook rejecting large attachments.
- Sending scanned contracts to clients.
- Forwarding brochure PDFs to mailing lists.
Common examples
- 12 MB scanned contract → Balanced compression often targets email-friendly sizes; text-only PDFs may barely shrink.
- Image-heavy brochure at 25 MB → Strong compression for upload portals; review text readability after download.
- Born-digital 2-page invoice at 400 KB → compression may show little gain; organize or split instead if still too large.
- 15 MB marketing PDF → Balanced mode for email; verify logos after download.
- Scanned 80-page packet at 45 MB → Strong mode for portal upload limits.

How it works
Upload a PDF and choose Basic, Balanced, or Strong compression. The browser uploads your file directly to private temporary storage using a short-lived link. A secure Ghostscript container compresses the PDF, then you receive a temporary download link. Original and compressed files are automatically deleted within one hour.
Limitations
Files upload to a secure server for compression and are auto-deleted within one hour. Scanned PDFs may not shrink much without OCR.
Privacy and file handling
Your file is uploaded securely for temporary processing. See the tool details below for retention behavior.
Important notice
Compression runs on a secure server with Ghostscript. Your file is uploaded privately and automatically deleted within one hour. Already-optimized PDFs may not shrink much. Maximum 50 MB and 200 pages.

Frequently asked questions
What size should I target for email?
Under 10 MB is safe for most providers; corporate gateways may require 5 MB or less.
