About Compress PDF

Big PDFs are slow to send and store. Our engine downsamples images to the right resolution and re-encodes them cleanly — so the file gets dramatically smaller while text stays crisp and readable.

  • Email PDFs that were too big to send
  • Speed up documents on your website
  • Save storage across bulk archives

How it works

  1. 1

    Upload your files

    Drop in your PDF — add as many as you need, or pick from your device.

  2. 2

    Set your options

    Tune a couple of settings to get exactly the result you want.

  3. 3

    Download the result

    Grab your file right away. Files are deleted automatically after an hour.
