Privacy-first daily-driver web tools that run **entirely in your browser** — your
files never leave your device.

**Live:** [https://goodwebtools.com](https://goodwebtools.com) · **Desktop app:** see [Releases](https://github.com/slaveofcode/goodwebtools/releases)

Most "online tools" upload your files to a server. GoodWebTools does the work client-side with WebAssembly, canvas, and on-device ML — so nothing is uploaded, tracked, or stored remotely.

Dozens of tools across **Dev**, **PDF**, **Image**, **Files**, **Draw**, **Media**,
and **Playground** categories — JSON/Base64/JWT utilities, image convert/compress/
resize/annotate, background & object removal, PDF↔image, an Excalidraw whiteboard,
a DB-diagram (DBML) designer, QR tools, and more. Browse them all at
[goodwebtools.com](https://goodwebtools.com).
