Large PDFs are hard to email or upload to government and university portals. Compress PDF recompresses embedded images with carefully tuned quality and optimizes the file structure, while text stays selectable and searchable.
How to use it
- Choose one or more files.
- Pick a level: extreme, recommended, or less compression without quality loss.
- Click “Compress PDF” to see the size before and after and the savings, then download.
Features
- Three levels for printing or sharing.
- Text remains real text, never converted to an image.
- Compress several files at once.
- If a file is already optimized, we keep the original instead of making it bigger.
Privacy and security
“Compress PDF” runs entirely in your browser using trusted open-source libraries. Your files are never uploaded to a server and no copy is kept, so your documents stay private. It is free and needs no sign-up.
Tip: Scanned and image-heavy files shrink the most; pure text files are already small.
