Transcode Video
Convert MOV, WebM, or MP4 to H.264 MP4 in your browser. Choose a maximum resolution and target video bitrate, then preview and download the result.
How to convert a video to MP4
Choose a local MOV, WebM, or MP4 up to 100 MiB, five minutes, and 4096 × 2160 pixels (or 2160 × 4096 in portrait). Conversion happens in your browser without uploading the video.
- Choose or drop a video from your device.
- Select a maximum resolution of 480p, 720p, or 1080p and a target video bitrate of 1.5, 3, or 6 Mbps.
- Choose Transcode, then preview or download the MP4 when it is ready.
Output codecs and browser support
The converter writes H.264 video and AAC audio if the source has a primary audio track. It omits extra tracks, subtitles, and source tags. It needs a browser that can decode the input and encode the output codecs.
A lower target bitrate can reduce the output size, but the final bitrate and file size can vary. The resolution setting fits the video inside the selected dimensions without enlarging smaller videos.
Example conversion settings
Choose the sample WebM and keep the 720p cap and 3 Mbps target. In a browser that supports the input and output codecs, the 160 × 90 video keeps its dimensions and the MP4 uses H.264 video and AAC audio.
After downloading, open the MP4 in the metadata viewer to verify its output dimensions, codecs, and tracks.
