About
Valn Tools is a collection of small, focused utilities for everyday tasks: formatting JSON, encoding text, generating IDs, counting words and more. Every tool is free and needs no account.
Your data stays on your device
The tools run as JavaScript in your browser. Text you paste and files you open are processed on your own computer or phone and are not uploaded to our servers.
This also makes the tools fast: there is no round trip to a server, and they keep working on a slow connection once the page has loaded.
How the tools are built
Each tool does one job, opens with a working example, and shows precise measurements of your data, such as line counts and byte sizes. Pages are served from Cloudflare’s global network and are available in English and Simplified Chinese.
