Compress PDF online

Shrinks image-heavy PDFs. Everything happens in your browser — the file is never uploaded.

Works by re-rendering each page as a compressed image, so it's most effective on scanned or image-heavy PDFs. Text-only PDFs may not shrink much.
About this tool

Make a PDF small enough to email or upload to a form. Choose a compression level and download a lighter copy. Best for scanned documents and photo-heavy PDFs; your file is processed on your own device.

How it works
  1. Open your PDF.
  2. Pick a compression level.
  3. Download the smaller file.
Questions
Why did my text-only PDF barely shrink?

Compression works by re-rendering each page as a compressed image, so it helps most with scans and photos.

Can I still select text afterwards?

No. Pages become images, so text is no longer selectable in the compressed copy. Keep your original.
