Make PDFs small enough to email. Pages are re-encoded to cut size dramatically, and you choose the quality level.

How it works

  1. 1Choose your PDF.
  2. 2Pick a level: high quality, balanced, or smallest size.
  3. 3Download the smaller file and see how much you saved.

Frequently asked questions

How much quality do I lose?

The balanced setting typically shrinks files by 50–80% with no visible difference for most documents. Always preview the result.

Why did my file barely shrink?

Files that are already optimised, or small text-only documents, leave little to gain. In that case keep your original.

Does text stay selectable?

With strong compression pages become images, so text is no longer selectable. Use high quality if you need selectable text.
