Hi everyone, I build some "online" converters as a side project in the last weeks. The difference to existing conversion websites is, that my converters don't upload your files. Everything happens in your browser on your device (with the help of a lot of great Open Source Javascript libraries). I think privacy is an essential feature for a service like this, so my converters also don't use google analytics or any other form of tracking (in fact they use no external resources at all). I started this because I ended up with some .heic files from my iPhone and had to use ImageMagick every time…

Most file converter sites upload your files to their servers. File Converter Free runs everything client-side using WebAssembly — your files never leave your device. 215+ formats across conversion and compression, 75+ browser-based tools for PDF, dev utilities, text, calculators and network diagnostics — all available in 9 languages. Built this solo. What tools do you wish ran client-side but currently don't? https://file-converter-free.com/en/tools

fileGOD▲3Just got tired of uploading passports, tax forms, and business contracts to iLovePDF and others after I've read they all store data. That made me built fileGOD. PDF compress, merge, split, and image conversion that runs entirely in the browser. There is no server endpoint that accepts file uploads. The processing pipeline uses WASM and runs on your device. We've ended up with full platform with 30+ pdf, image and utility tools. Would love feedback on quality of the tools you use and overall UX.
