Security Tools

Protect your privacy with browser-only processing.

Privacy tools are only trustworthy if you can verify what happens to your data. Every security tool here runs on your device: EXIF metadata is stripped from photos, AES-256 encryption and HMAC signing use the Web Crypto API locally, and file hashes are computed in your browser. There is no backend, so there is nothing to intercept or retain.

FAQ

Security Tools — frequently asked questions

Is AES encryption really done offline?

Yes. The AES-GCM key is derived from your passphrase in your browser using the Web Crypto API. Neither the plaintext nor the passphrase ever leaves your device.

What EXIF data does the cleaner remove?

GPS coordinates, camera make and model, timestamps, and software tags — everything the file's metadata blocks reveal. The cleaned file keeps its visual quality.

Can these tools help with passwords?

Yes. The password generator creates strong random passwords with cryptographic randomness, and the strength checker scores entropy and flags weak patterns.
