Webtools

Webtools is a free collection of everyday developer utilities — encoders, formatters, generators, and testers — that live in one tab instead of ten different websites. Nothing requires an account or installation: open a tool, do the thing, close the tab. Where a tool's job doesn't need a server at all — generating a password, converting text case, building placeholder copy — it runs entirely in your browser and nothing you type ever leaves your device; where server-side processing genuinely helps, your input is used for that one request and immediately discarded.

Four kinds of tools

Encoding & conversion

Translate data between the representations different systems expect: Base64 and percent-encoding for text that has to survive systems built for plain ASCII, color formats for design work, Unix timestamps for anything that stores time as a number, and YAML/JSON conversion and QR codes for moving data between tools and devices.

Formatting & code

Minify JSON, JavaScript, CSS, HTML, and XML for production, or beautify any of them back into something a human can actually read and review — the same operations, run in reverse.

Security & identifiers

Generate the fingerprints and identifiers software relies on: cryptographic hashes, random UUIDs, unique passwords drawn from your browser's own secure random number generator, and a JWT decoder for reading the tokens issued by login systems.

Generators & testing

Build and test text rather than transform it: a live regular-expression tester, a cron-expression explainer that shows the next five run times, a case converter for identifier naming, and a lorem ipsum generator for filling layouts before the real copy exists.

Frequently asked

Do I need to create an account?
No. Every tool works immediately, with no sign-up, login, or installation. Some tools use a server for the one request you make; none of them keeps a history of what you've used.

Is any of this stored or tracked?
Input you paste into a server-backed tool is processed for that one request and then discarded — nothing is logged. Tools that can run entirely in your browser, like the password generator and case converter, never send your input anywhere at all.
