About DivXpress

DivXpress is a small, independent video tool with one strong opinion: converting a video should not require handing it to a stranger's server first. Most online converters ask you to upload your file, wait in a queue, and trust that it gets deleted afterward. We thought that was backwards.

So DivXpress does the work in the other direction. The conversion engine, a WebAssembly build of the well-known ffmpeg project, runs inside your own browser. When you drop a file in, it is read from your device, processed on your device, and handed back to you on your device. Nothing is uploaded. There is no server that ever sees your video, which means there is nothing for anyone to store, mine, or leak.

What it does

DivXpress converts between common formats, compresses video to a smaller size, turns clips into GIFs, and extracts audio as MP3. It is free, needs no account, and never stamps a watermark on your output. The trade-off of running locally is that very large files depend on your device's memory, so it is happiest with everyday clips rather than feature-length footage.

Who it is for

Anyone who needs a quick, one-off conversion without installing software: someone shrinking a clip to fit an upload limit, converting an iPhone recording so a colleague can open it, or pulling the audio from a talk. If you convert video all day for a living, a dedicated desktop app will serve you better. For the occasional job, DivXpress is meant to be the fastest honest option.

Honesty about limits

We would rather tell you the constraints up front than oversell. In-browser conversion is slower than a native app for big files, some exotic codecs will not decode, and the first run downloads the engine once. In exchange you get privacy, no upload wait, and no sign-up. That trade is the whole point of the project.
