Convert a video to the format you need

Open the converter, drop in an MP4, MOV, WebM, or MKV file, choose the output format, and convert. The new file saves straight to your device, so there is no upload step and no account to create.

Yes, completely. There is no sign-up, no trial, and no watermark on the file you get back.

No. The work happens locally in your browser through WebCodecs, so the file is never sent anywhere and nothing is kept on a server.

It reads MP4, MOV, WebM, and MKV files and writes back MP4, WebM, MOV, or MKV. MP4 with H.264 is the default because it plays almost everywhere. AVI, FLV, and WMV are not supported, so convert one of those with another tool first.

MP4 plays on the most devices and apps, which is why it is the default. Pick WebM for a smaller file aimed at the web. MOV and MKV are there for a specific app or workflow that asks for them.

The converter keeps the original resolution and frame rate. The video is re-encoded to the new format, so a single frame paused and zoomed in can look a touch softer than the source. In motion the clip looks the same.

Yes. Alongside the output format you can set a quality, change the frame rate, remove the audio track, or strip metadata before you convert. Removing the audio drops it from the video; to save the audio by itself as an MP3, use the Extract audio tool instead.

Yes. The converter runs in your phone browser, so it works on iPhone and Android with no app to install. A phone has less memory than a computer, so a very large file is easier to convert on a desktop.

There is no server limit, because nothing is uploaded. The practical ceiling is your device memory, so typical clips and recordings convert with no trouble; a very long, high-resolution file is heavier on an older device.
