About GrowNiti Labs Dev Tools

Small, fast tools for everyday developer jobs: converting data formats, tidying JSON, encoding and decoding, hashing and generating test data.

Every tool runs in your web browser. When you paste data or open a file, it is processed on your own device with JavaScript. Nothing is sent to a server, nothing is stored, and you do not need an account.

Dev Tools is part of GrowNiti Labs, a digital studio that also makes finance calculators and image & pdf tools and travel planner.

Every tool runs in your web browser. Text you paste and files you open are processed on your own device. We do not upload, store or sell them, and you do not need an account.

If you switch theme, that choice is saved in your browser so the site remembers it. Pages load fonts from Google Fonts, so your browser connects to Google’s servers to download them. We do not use advertising or tracking cookies; if that changes, this notice will be updated first.
