Same quality bar. Still free. Still no upload.
Your files never leave your device
Free to use, with no account, no usage limit and no watermark, because the work runs on your device rather than on our servers.
This is not a promise about how carefully we handle your upload. There is no upload. The file you choose is read into memory by your own browser, processed there, and handed back as a download — the tool has no server component and makes no network request with your data.
- Nothing is stored. We never receive the file, so there is no copy to retain, no retention period to disclose, and nothing to delete on request.
- Nothing is transmitted. No upload endpoint, no analytics payload carrying file contents, no third-party processor.
- You can verify it. Load this page, disconnect from the internet, and use the tool. It still works, because everything it needs is already on your machine.
- Nothing persists after you close the tab. Files are held in page memory only — not in local storage, not in a cache, not in a database.
A note on wording, because it matters: we do not describe these tools as “encrypted.” Encryption protects data that travels to somebody else's computer. Your file does not travel, so there is nothing to encrypt and nothing to intercept — which is a stronger guarantee than encryption, not a weaker one. The page itself is served over HTTPS like the rest of the site.
This makes the tools safe for material you are contractually barred from uploading to third-party services — client footage under NDA, unreleased campaign assets, anything covered by a confidentiality clause.
How it works
1. Drop a PDF
Up to 150 MB and 500 pages, opened in your browser.
2. Set quality and scale
Each page is redrawn as a JPEG at the quality and scale you choose.
3. Download the -compressed PDF
Compare the new size with the original before you send it.
Questions
Will my text stay selectable?
No. Compression here rasterises every page. The result is a picture of the page, which is why photo-heavy PDFs shrink and why you should keep the original if you still need copy-paste.
Why is the file larger after compress?
A lean vector or text PDF can expand when every page becomes a full-frame JPEG. Lower quality or scale helps only so far. This tool reports when the output is larger than the input.
Which settings shrink the file most?
Two sliders: JPEG quality from 0.4 to 0.92 (default 0.72) and render scale from 1x to 2.25x (default 1.5x). Lower values give a smaller file but softer pages, so check small type in the result before you send it.

These rearrange files. Versely makes new ones.
Everything on this page works on a file you already have, which is why it costs nothing. Generating something that did not exist (video from a prompt, a voice, a score) runs a model, and that costs credits.
