Hi Product Hunt, I'm Thien, the maker of ToAny. Most online converters make you upload your file to a server you know nothing about. That's a nuisance for a HEIC photo and a real problem for a contract or a spreadsheet. ToAny converts in your browser instead: the file's bytes, name and size never leave your device. How it works: drop any file (the type is detected from the file's contents, not its extension), pick what it should become, and it converts locally with WebAssembly and your browser's own codecs. Batches download as a ZIP. Being upfront about the limits: 31 of the 1,123 format pairs (Office to PDF, e-books) can't be done well in a browser, so they run on a server. Those are labelled, ask for your consent before each upload, and the file is deleted after conversion. Large videos are bounded by your device's memory and can be slow on phones. It's free, with no sign-up. I'd love to hear which format pair is missing and what breaks for you.
