As answered by people managing OrpheusTools.app and DEVONthink.
OrpheusTools.app's answer
Every other online file converter uploads your document to a server, processes it there and sends it back. Orpheus does the work in the browser: the file is read into memory on your own machine, processed with WebAssembly and the browser's own codecs, and handed straight back. No file is transmitted, and you can verify that rather than trust it — open the network tab and watch it stay empty while a tool runs. There is no account, no queue, no watermark and no file size limit.
OrpheusTools.app's answer
Three reasons. Privacy is structural rather than a policy: there is no server holding your file, so there is no retention promise to trust. Breadth: 169 tools covering PDF, image, text, developer utilities and 96 calculators, so one site replaces several. And speed: with no upload and no download round trip, a 30 MB PDF is finished in less time than the upload alone would take. Pages hold LCP under a second on a throttled mobile connection.
OrpheusTools.app's answer
People handling documents they would rather not hand to a third party: contracts, CVs, medical letters, bank statements, passport photos. In practice that is a wide group — students, freelancers, small businesses, developers, and anyone who has hit a file size paywall on a free converter. The site is built mobile-first, because people convert a file on the device it is already on.
OrpheusTools.app's answer
It started from noticing that every mainstream online converter receives your file, and that for the documents people actually convert — a signed contract, a CV, a scan of an ID — that is a bad trade for a thirty-second task. The browser turned out to be far more capable than expected: createImageBitmap and OffscreenCanvas already handle the JPEG/PNG/WebP triangle with no library at all, and pdf-lib handles PDFs inside a Web Worker. Everything grew from there to 169 tools and 43 guides, each one a single config file checked by a build gate.
OrpheusTools.app's answer
Next.js 16 with the App Router, statically exported — every page is prerendered, there is no server and no cold start, and the site is served as assets from Cloudflare. Processing runs in Web Workers: createImageBitmap and OffscreenCanvas for JPEG, PNG and WebP, WebAssembly for formats the browser cannot decode natively, and pdf-lib for PDFs, loaded as its own chunk so it arrives only when you click the button. TypeScript throughout, in a pnpm workspace.
