I got tired of uploading files to random online converters and wondering what happens to them on the other end. Legal docs, client photos, personal stuff. It felt wrong.
So I built Private Convert, a file converter that runs entirely in your browser. No upload, no server, no account. The conversion happens locally using WebAssembly and the HTML5 Canvas API. You can turn off your WiFi mid-conversion and it still works.
It supports 30+ format pairs: HEIC, JPG, PNG, WebP, SVG, PDF, HTML. Everything is client-side. The site is also available in 7 languages.
I'll be writing a deeper post soon about how WebAssembly makes this kind of thing possible, and why more tools should work this way.
Happy to answer questions in the comments.
