About Tool Fu

Tool Fu is a collection of 80+ free, browser-based developer tools. Every tool runs entirely in your browser — no files are uploaded, no data leaves your device.

Built by Yash Gandhe.

Why Tool Fu?

Most online tools upload your files to a server. Tool Fu takes a different approach: everything runs client-side. Your JSON, images, PDFs, and code never leave your machine.
