Convert Video

Convert a video between MP4 and WebM locally. The browser picks the best encodable codec for your chosen container, and the file never leaves your device.

Supports: MP4, WebM, MOV
Maximum: 250 MB per video

If the source codec can be placed in the target container unchanged, the conversion is lossless; otherwise the video is re-encoded locally.

Private: processing happens locally in your browser.

How it works

  1. Choose a video file
  2. Select MP4 or WebM as the target format
  3. Convert locally and download the converted video

Use cases

  • Turn WebM downloads into MP4 for editors
  • Produce WebM copies for modern web pages
  • Move phone footage into a format a site accepts

Supported formats

Input: MP4, WebM, MOV

Output: MP4, WebM

Limitations

  • A conversion re-encodes whenever the source codec cannot be placed in the target container unchanged.
  • Browsers that lack a needed encoder (for example WebM output in Safari) cannot convert to that format.
  • Files up to 250 MB are supported; larger videos may exceed your device memory.

Privacy

Processing happens locally in your browser. Your file is not uploaded to iAgent7 Tools or a third-party API.

File names, file contents, and results are not sent to analytics or error logs.
