1

Open a tool.

Pick what you need. Each tool is a single focused page.

2

Drop your file.

Files are read by a script on your device. They are not sent anywhere.

3

Done.

View, copy or download the result. Close the tab and it is gone.

How it works.

Are my files uploaded?

No. Every tool runs in your browser. Files and text never leave your device, and there is no server to receive them.

Do I need an account?

No. There is no sign-up, no paywall and no limit on how often you use a tool.

Does it work offline?

Once a page has loaded, the tools keep working without a connection, because the processing is local.

Which tools are coming?

JSON, Base64, JWT, regex, diff, hashing, text and image helpers. See the “Coming next” section above.
