Compress PDF online — free, in your browser
Need to shrink a PDF so it's easy to email or upload? We added a free tool that does exactly that — PDF Compressor — and it works online, right in your browser, with nothing to install.
What it does
Add a PDF and download a smaller version — the same document, just a lighter file. No watermark, no email, no account.
Your files never leave your device
This is the part most "free" sites get wrong — they upload your documents to a server. Ours doesn't. The compression happens on your own device, inside the browser. Nothing is uploaded and nothing is stored, so it's safe even for contracts, invoices or anything private.
How to use it
- Open PDF Compressor.
- Add your PDF.
- Download the smaller file — it takes a couple of seconds.
It's free with no limits. If it's useful, we have more small tools like it — they're all on the Apps page.
