A complete developer utility belt — without the data risk
Most online developer tools you find on Google paste your data into a remote server, often logging it for "abuse detection". When that data is a JWT, an API response, a customer email list or a database dump, that's a real security incident waiting to happen. IMTools rebuilt the most-used developer utilities — JSON formatter, Base64 encoder, hash generator, regex tester, UUID generator, CSV/JSON converter — to run entirely in your browser using vanilla JavaScript. Nothing is sent to any server, nothing is logged, and nothing is stored beyond the current tab.
Designed for daily workflows
Each tool is opinionated about defaults so you don't have to think: the JSON formatter respects 2-space indentation, the regex tester highlights capture groups inline, the UUID generator outputs v4 by default but lets you pick v1/v3/v5, and the hash generator produces MD5, SHA-1, SHA-256 and SHA-512 in one go. Outputs are copyable with one click and downloadable as files where it makes sense. Diff Checker is line-and-character based so you can spot a single character change in a config file.
Privacy and performance
Everything is implemented with the Web Crypto API, native browser TextEncoder/Decoder, and small focused libraries (uuid, qrcode) rather than heavy frameworks. Pages load in well under a second, work fully offline once cached, and respect your system's dark mode. There are no trackers beyond a single anonymous analytics ping per page view, and no third-party scripts in any tool's processing path.
