How to use this tool

  1. Choose a supported video.
  2. Select MP4 or WebM output and target file size.
  3. Run local processing and download the converted file.

First-version converter scope

This page supports the adjacent format-conversion task, while the MVP remains focused on MP4/MOV compression and local browser processing.

MP4 remains the safest default

Use MP4 for email, chat apps, and most upload forms. WebM is available when browser support and output needs match your use case.

Browser-based compression and privacy

The video file is handled in your browser session. The compression engine runs locally, so the file is not uploaded to a server and no watermark is added.

Supported formats

The first version accepts MP4, MOV, and WebM files up to 500MB. Files from 200MB to 500MB can be processed, but the page warns that browser memory and processing time may be a limit.

FAQ

Can I convert MOV to MP4?

Yes. Choose a MOV file and keep MP4 as the output format.

Can I output WebM?

Yes, WebM is available as an optional output format when browser FFmpeg support allows it.

Is this a full multi-format converter?

Not yet. The first version focuses on MP4, MOV, WebM input and MP4/WebM output for browser-based compression.
