Every tool here does its work locally: your files are read by JavaScript and WebAssembly inside the tab and never leave your machine. Merge or diff two CSVs, clean and edit rows, convert between document, image, audio, and video formats, pull text out of scans with OCR, strip metadata, hash files, compress, or anonymize columns before you share them. There's also a local Gemma AI chat that runs on your GPU via WebGPU, so even the AI features stay offline. Close the tab and nothing is left behind on any server.
No. Every tool processes files inside your browser tab using WebAssembly. Nothing is sent to a server, so your data stays on your device even for the AI chat.
No install and no account. Open the page in a modern browser and start working. After the first visit most tools keep working with no connection.
It's free with no sign-up. Because processing happens on your machine, there are no per-file server costs to pass on and no reason to collect your data.
Every tool runs entirely in your browser. Files are never uploaded — 100% private and free.
