Why Swoosh

The free tool that doesn't hold you back.

Runs in your browser

The PDF tools process your file on your own machine — there is no upload step and no queue.

No two-a-day wall

Most free PDF sites cap you at a couple of tasks a day. Here the core tools are unlimited, no account needed.

Never stamped

No watermark on your output, ever. The result is yours, clean, on the free tier too.

How it works

Compress PDF downsamples and re-encodes the images inside the file, leaving text and vector graphics untouched, so the size drops without the page going blurry.

When to use it. Use it to email a large PDF, beat an upload limit, or hit a target size such as 1 MB or 500 KB.

Limits. Best on image-heavy or scanned PDFs; a text-only PDF is already small, so there is little to squeeze.

Runs in your browser, no upload step.
