Free tools for small data jobs. Browser tools keep what you paste on your own machine.
This is a catalog of single-purpose tools: hashes and checksums, encoders and decoders, text converters, validators, file inspection. Nothing here needs an account. You open a tool, give it your input, and take the result.
Browser tools never send it.
A browser tool downloads a WebAssembly module and runs it locally, so the text you paste or the file you choose never leaves your computer. The module is built without host access, which means it has no way to open a network connection or reach anything except the input you hand it.
Working locally also lifts the size limit. A tool running in your browser accepts up to 60 MiB of input, against 20 MiB for anything that has to reach the server.
A tool that works this way says Runs in your browser above its input, so you know before you paste anything.
No account is needed to run a tool, so most visits leave nothing behind at all.
When a tool does run on the server, your input is held only while it is being processed and removed once the run finishes. The result stays for at most 24 hours so you can download it, behind a hashed key that other people cannot reach. We do not read it and we do not reuse it. While it exists, it sits in the EU.
We keep small first-party execution-health totals without tool inputs or outputs.
