Compress PDF for Email: free online tool

Most email services let you attach files up to about 20 to 25 MB in total, and the person who receives it may have a smaller limit. A PDF full of scans or photos can pass that quickly.

Add your PDF, keep Recommended selected and press Compress PDF. Check the before and after sizes, then download the smaller file.

How to compress a PDF

  1. Drop your PDF on the box or tap it to choose a file.
  2. Choose how small you want it: Light, Recommended or Smallest. For a form with a size limit, tick I need an exact size and type it.
  3. Press Compress PDF and wait a moment while the pages are processed.
  4. Check the before and after sizes and the first page, then press Download PDF.

Tips

  • Several attachments count together. Compress each PDF, then check the total.
  • If it must be tiny, tick "I need an exact size" and type a limit such as 1 MB.
  • For a long document, you can also split it into two emails.

Compress PDF for Email: common questions

It depends on the email service. Many allow about 20 to 25 MB per message, and the receiving service can have its own, smaller limit. Keeping a PDF under a few MB is the safe choice.

The pages look the same at normal viewing size, but they are saved as pictures at a lower resolution, so the text cannot be selected and very fine detail can be softer.

Yes. The PDF is processed in your browser and never uploaded to a server.

Yes. It is free, needs no account, has no daily limit and does not add a watermark.

No. The PDF is opened and rewritten inside your browser. It never leaves your device, so private documents stay private.

Tick "I need an exact size", type 200 (or 100) and choose KB, then press Compress PDF. The tool tries stronger and stronger settings until the file is under your limit. A very long PDF may not reach a very small limit, so try Black and white too.
