About these tools
These privacy tools are local-first: each one runs in your browser, so the files and text you work with stay on your device and are never uploaded to a server. That distinction matters — many online utilities send your file to a remote machine to process it, while these specific tools do the work right where you opened them.
The set covers the everyday tasks where leaking information is easy to do by accident. Use the Image Metadata Remover to strip hidden data before posting a photo, the EXIF Data Viewer to see what a picture is actually carrying, and the Text Redactor to black out sensitive details. The Fake Data Generator produces realistic placeholder records for testing, and the Hash Generator and Credit Card Validator help you check values without handing them to anyone.
Because nothing is sent anywhere, there is no account, no sign-up, and no copy of your data sitting on a server afterwards. Always keep your own backup of an original file before stripping or redacting it, since the changes these tools make are meant to be permanent.
Frequently asked questions
No. These specific tools — the Image Metadata Remover, EXIF Data Viewer, Hash Generator, Text Redactor, Fake Data Generator, and Credit Card Validator — run entirely in your browser. Your files and text stay on your device and are never sent to a server.
Metadata is hidden information stored inside a file — a photo can carry the camera model, date, and even GPS location. Removing it before you share a file prevents that hidden detail from traveling with it. The EXIF Data Viewer lets you see what a photo contains first.
The Text Redactor removes the characters you select rather than just covering them, so the underlying text is gone from the output. Keep a separate copy of the original if you need it, because the redaction is intended to be permanent.
Yes — it creates realistic but made-up records so you can populate test environments and forms without using anyone real personal data. The output is fictional and not tied to any actual person.
