Most online MP4 converters upload your video to a server, store it for hours, and require signup or paid tiers to remove watermarks. Morphix is different: every conversion runs locally in your browser using WebAssembly. Your files never leave your device, there's no signup, no queue and no watermark — and it keeps working offline after the first load.
Yes — no signup, no watermark, no upload. Forever.
No. Every conversion runs in your browser using WebAssembly. Files never leave your device.
MOV, MKV, AVI, WebM, GIF, 3GP, FLV, WMV and many more are supported. You can also extract audio from MP4 to MP3.
Morphix uses a high-quality preset by default. Resolution and bitrate are optimized automatically for the best balance of quality and file size.
Most short videos convert in under a minute. Longer files may take a few minutes depending on length and your device speed. Everything happens locally — there is no queue.
Yes. Drop several files into the converter and each will be processed one after another. You can download each result as it finishes.
Yes. After the first load, all required WebAssembly modules are cached. You can convert MP4s on a plane, in a tunnel, or anywhere without internet.
There is no artificial limit, but very large files (over 1 GB) may take longer depending on your browser and RAM. Most users convert files under 500 MB smoothly.
