About

dontsendfile.com is a privacy-first file utility platform. Every tool on this site processes your files entirely in your browser — nothing is ever uploaded to a server.

Your files never leave your browser. All conversion, compression, and transformation happens locally on your device using WebAssembly and client-side JavaScript.

We built this because too many online file tools require you to upload sensitive documents to unknown servers. We believe you shouldn't have to trust a stranger with your files just to convert a document.
