More free privacy tools
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, read in your browser.
2. Scan the text
Page text and metadata are checked for emails, phone numbers, card numbers and ID-style strings.
3. Fix before you share
Each match lists its page, so you can redact it before sending.
Questions
It flagged something that is not a real ID. Why?
The scanner looks like a recipient would: regular expressions, not an identity bureau. A product code that happens to look like a National Insurance number will show up. Treat every hit as 'this string is in the file', then decide whether it is actually sensitive.
It found nothing, but I can see the info on the page.
Then the page is almost certainly a scan. There is no text layer to extract, so there is nothing for a pattern to match. the same reason you cannot select the letters in a viewer. Raster text needs OCR, which is a model, not a parser.
What does it look for?
Email addresses, phone numbers, US Social Security-style numbers, UK National Insurance-style numbers and card numbers that pass the Luhn check. It scans every page's text and the document metadata fields. It reports matches; it does not redact them.

Stay in the same job cluster. Free tools stay on-device; paid tools are labelled as such.
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.
