Hi Product Hunt! I built OneFileConverter because most online converters upload your file to their server, even for simple jobs like compressing a PDF or turning a HEIC photo into a JPG. That's a problem for IDs, contracts and medical papers.
OneFileConverter does the work inside your browser instead (Web Workers, WebAssembly and WebCodecs), so the file stays on your device. It has 100+ tools across PDF, image, video and audio, including compressing a PDF to an exact size (handy for upload forms with a 100 KB or 200 KB limit), OCR, signing, background removal with an on-device AI model, and video trimming. It's free, with no sign-up and no watermark, and it's available in 10 languages.
I'd love your feedback: which tool did you try, what was slow or confusing, and which tool should I add next?
