About isso.fun

isso.fun stands for "is so fun" — a growing collection of free, browser-based tools across different domains. Each subdomain is a self-contained toolkit: media is so fun, color is so fun, text is so fun, and so on.

Our core belief is simple: everyday tools should be free, fast, and private. Every tool on isso.fun runs entirely in your browser using modern web technologies like WebAssembly. Your files and data never leave your device — there's no server processing, no upload queue, and no account required.

What's live today

media.isso.fun — our first project — offers 11 free tools for video, audio, and GIF processing: compress, convert, trim, extract audio, make GIFs, and more. All powered by ffmpeg.wasm running locally in your browser.

What's next

We're exploring tools for color (palettes, contrast checking), text (formatting, encoding), and data (JSON, CSV, visualization). Each will follow the same principle: browser-first, no upload, free to use.
