Compress PDF

Shrink a large PDF down to a smaller file. This works by re-rendering each page as an image at your chosen quality — great for scanned documents and photo-heavy PDFs, but text stops being selectable, so it's not the right choice for a PDF you still need to copy text from.

How it works

1. Upload your PDF — Choose the file you want to shrink.
2. Pick a quality level — Higher quality keeps more detail; smaller size saves more space.
3. Download — Get your compressed PDF.

Processing happens in your browser — nothing is sent to a server to do the actual work. We also keep a copy of what you upload, for support and to improve the tool. Compress flattens each page to an image, so text is no longer selectable in the result.
