Your video never leaves your device — conversion runs entirely in your browser.

How it works

Video converter re-encodes a recording to MP4, WebM, MOV, MKV or an animated GIF right in your browser, and can pull the soundtrack out on its own — the file is never uploaded and never leaves your device.

MP4 plays everywhere — pick it if you are not sure. WebM is smaller at the same quality. GIF is for the places that still accept nothing else. MOV is the QuickTime container that editing software expects, and MKV is what media servers and archives tend to want; both carry the same video as MP4, just in a different box.

Choose GIF with care: it stores every frame in full, so a clip that is a couple of megabytes as WebM can run to hundreds as a GIF. We do not cut the length for you — instead we show how many frames you will get and roughly how large the file will be, and leave the choice to you. Frame rate is picked from a list because the format cannot carry every value, and we only offer the ones it reproduces exactly. GIF has few colours, so smooth colour changes can come out as visible bands. And GIF has no sound at all — the audio track is dropped.

M4A and WAV drop the picture and keep only the sound. M4A is the one to pick: when the video already carries AAC the track is copied across without re-encoding, so it is instant and loses nothing. WAV is uncompressed, around 10 MB a minute, and is worth it only when something you use demands that format. MP3 is not offered because no browser can create it.

MP4 and WebM keep the sound. If that turns out not to be possible for your file, we say so before starting.

Long videos take a while — better not to close the tab. You need a recent browser: Chrome, Edge, Safari, or Firefox on a computer.

  1. Drop a video onto the page or pick a file. It stays on your device — there is no upload to wait for. The practical size limit comes from your device’s memory, not from a number we set.
  2. Choose the output: MP4 if it needs to open anywhere, WebM for the same quality at a smaller size, MOV for video editors, MKV for media servers and archiving, GIF for a short looping animation with no sound, M4A or WAV to keep just the soundtrack.
  3. Set the quality and, if you want a lighter file, reduce the resolution. Dropping the audio track saves a little more.
  4. For GIF, set the size, pick a frame rate from the list and mark the part you want. Nothing is trimmed for you: below the settings you can see how many frames you will get and roughly how large the file will be — the trade between size and smoothness is yours to make.
  5. Press Convert and keep the tab open — you will see the progress and roughly how long is left. When it finishes, download the result or start again with another file.
