Why we built browser-only tools
Most online conversion sites upload your file to a server, run a short script, send the result back, and quietly keep a copy. For a holiday photo that's a minor annoyance. For a residency visa scan, a payslip or a signed NDA, it's a data leak waiting to happen.
The 21 tools on this page do the work entirely inside your browser using WebAssembly and the modern File System Access API. No file we touch is ever transmitted to a Dubinity server. We cannot read it, we cannot store it, and we cannot recover it if you close the tab. If you're curious how that works technically, every tool is open about the library it uses — pdf-lib for PDFs, browser-image-compression for images, ffmpeg.wasm for video — and all run inside a sandboxed worker.
