Why Omnipus

Search engines are full of converters that quietly upload your files. Omnipus is built the other way around: PDF, image, and audio tools run with WebAssembly and the canvas API inside your browser. We do not keep a copy.

Downloaders are the exception — they fetch a public URL you paste, and only to extract media you already have the right to save. Currency conversion reads European Central Bank reference rates. Everything else stays local.

The catalog covers the most-googled utilities: PDF to Word, background removal, MP4 to MP3, Instagram Reels, TikTok, QR codes, EMI math, and a hundred more. New tools join the universe as search demand shifts.
