File converters and 75 tools that run in the browser

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
