Compress a PDF to under 500 KB
Shrink PDF files for email and upload limits. Two modes: lossless clean-up, or strong compression of scanned pages. Private, free, in your browser.

Your files stay on this device. Nothing is uploaded.
Application portals, tender systems and some e-mail gateways cap attachments at 500 KB. This preset compresses your PDF until it fits, on your device, with nothing uploaded. Text stays selectable unless the strong mode is needed.
How it works
- Drop your PDF files.
- Pick lossless or strong, and a target size if you have a limit to meet.
- Compress and download.
This tool runs entirely in your browser. Your files are never uploaded, so there is no size limit and it works offline once loaded.
Common situations
Frequently asked questions
Is it really free and private?
Yes. Everything runs in your browser with open-source code; nothing is uploaded. No account, no watermark, no file-size limit other than your device's memory.
Will text stay selectable?
In lossless mode, yes. Strong mode rasterizes pages, so text becomes an image; use it for scans and photo documents, not for text you need to copy.
Why is my PDF not getting smaller?
Because it is mostly text and vectors, which are already compact. Only images have room to shrink.
