What is a PDF compressor?

A PDF compressor reduces file size so documents fit email limits and upload portals. Choose a compression level and download a smaller PDF after secure processing.

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.

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.

FAQ

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.

Will compression affect signatures?

Visual appearance of scanned signatures may soften at high compression—preview before sending.

Can I compress multiple PDFs?

Compress each file separately, or merge first then compress if one attachment is acceptable.
