About this tool

This free Compress PDF tool makes a PDF smaller so it's easier to email, upload or store. It works entirely in your browser and is especially effective on scanned documents and image-heavy PDFs.

Choose a compression level, and the tool re-encodes each page to shrink the file. Nothing is uploaded to a server.

Features

  • Three levels — Strong, Balanced or Light
  • See the before and after size and how much you saved
  • Works on documents of any length
  • 100% in your browser — your PDF is never uploaded

Good to know

  • This compressor rasterizes pages (re-encodes them as images), which is why it shrinks scanned and image-heavy PDFs so well. A side effect is that selectable text becomes part of the image, so use it when smaller size matters more than text selection.

How to use it

  • Upload a PDF — click the upload area or drag and drop
  • Pick a compression level — Strong, Balanced or Light
  • Compress — then check the new size
  • Download — save the smaller PDF
