Compress PDF
Shrink a PDF's file size so it's easier to send.
To compress a PDF, pick a level and run: pages are recompressed and the file gets lighter, ideal for email. Everything runs in your browser: the file is never uploaded to a server.

The final size is shown after compression, so you can compare it with the original at a glance.
Nothing is uploaded
Recompression happens in the browser; your documents never leave your device.
Use cases
- Send a too-heavy PDF by email or messaging.
- Slim down an application file before uploading it.
- Reduce a high-resolution scan for archiving.
- Publish a lighter document on a website or intranet.
Your files never leave your device
Unlike most online PDF tools that upload your files to their servers, all processing happens right here, in your browser. No document is ever sent, stored or analyzed remotely: it's free, no sign-up, and private by design.
Frequently asked questions
- Does quality drop?
- Compression rasterizes pages: the look stays sharp but text is no longer selectable. Pick “Light” for best quality.
- How much smaller does it get?
- Savings depend on content: image-heavy PDFs compress a lot, mostly-text ones less.
- Does text stay selectable?
- Since pages are recompressed as images, text becomes non-selectable. Run OCR afterwards if you need it back.
- Are my files uploaded to a server?
- No. All processing happens in your browser: your files never leave your device.
