About Morphix
Morphix is a free file converter that runs entirely in your web browser. No uploads, no accounts, no quotas — just drop a file and download the new format.
Our mission
Most online file converters work the same way: you upload your file to a server, a stranger's machine does the conversion, and you trust that the file is deleted afterwards. For sensitive documents, personal photos, voice memos, or work-in-progress media, that's a bad trade. Morphix exists to prove that the trade is unnecessary — modern browsers can do the conversion themselves.
How it works under the hood
Morphix is a single-page web app that loads a set of WebAssembly modules on demand. Images go through the browser's native decoders and the Canvas API. Audio and video go through ffmpeg.wasm — a port of the venerable FFmpeg project compiled to WebAssembly so it can run inside the tab's sandbox. When you drop a file, the bytes are read into memory, processed locally, and a new Blob is handed back to you as a download. Nothing is ever sent to a server.
100% local
Files never leave your device.
No queues
As fast as your machine can run.
Works offline
Once loaded, no network needed.
Who's behind it
Morphix is built and maintained by a small independent team that cares about web standards and user privacy. We're not a venture-funded company, we don't sell your data, and we don't have a sales team. If you want to reach us, the contact form is the best way.
How we keep the lights on
Running a website costs money even when conversions are free. We cover hosting through three honest channels: display ads served by Google AdSense on a small number of placements, affiliate links (currently NordVPN — clearly marked), and voluntary donations from users who find the tool useful. Ads never see your files — they only see the webpage, like any other ad on the open web.
Open about the tech
Built with TanStack Start, React, Tailwind, ffmpeg.wasm and the Canvas API. Hosted on Cloudflare's edge network. Source files for each conversion stay in the page's memory and are released when you close the tab.
