53 free tools that never touch a server

Your files never leave your device

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.
