Compress PDF
Reduce PDF file size by re-rendering pages as JPEG at the quality you choose, or with a lossless clean-up.
About Compress PDF
This free tool helps you reduce PDF size online when a form, portal or email rejects a large file. Pick Image compression for the biggest savings on scanned documents and photo-heavy PDFs, or Lossless clean-up to shrink the file while keeping text selectable. Presets make it simple, and you can fine-tune resolution and JPEG quality yourself.
After compressing, you see the before and after sizes so you know whether the file now fits a limit like 200 KB or 500 KB. Scans usually shrink a lot; text-only PDFs are already compact. Your PDF is processed entirely in your browser and never uploaded, and there is no sign-up or watermark.

Frequently asked questions
Are my files uploaded anywhere?
No. The file is opened and processed entirely inside your browser using JavaScript libraries. Nothing is sent to a server, so it is safe for confidential documents.
Why is the text no longer selectable?
Image compression turns every page into a picture, which is what makes the file much smaller for scans and photo-heavy PDFs. Use Lossless clean-up if you need selectable, searchable text.
Which preset should I use for government portals?
Portals that ask for files under 200–500 KB usually accept Smallest file (72 DPI). For documents that must be printed, use Best quality.
The compressed file is bigger — why?
Text-only PDFs are already compact. Rendering them as images can make them larger; in that case keep your original file or use the lossless mode.
How do I compress a PDF to 100 KB or 200 KB?
Choose Image compression with the Smallest file preset, then check the new size. If it is still too big, lower the resolution or JPEG quality and compress again. Very long documents may need splitting first.
