    Questions

    How much smaller will my video get?

    Phone videos are recorded at high bitrates, so the balanced preset usually saves half or more with no visible change. The smaller presets also lower the resolution: a 1080p clip at 720p is often a fifth of the size.

    How does the target size work?

    Size is bitrate times length. The tool divides your limit by the video’s length, keeps a little margin, and leaves room for the sound. For very small limits it also lowers the resolution, which looks better than squeezing a large picture.

    Which format is the result?

    MP4 with H.264 picture and AAC sound: it plays on every phone and site.

    How long does it take?

    Copying without re-encoding takes seconds, even for long videos. Re-encoding runs at roughly real time or faster on a recent computer, using its video hardware; phones are slower.

    Is there a size limit?

    Up to 4 GB per video on a computer (1 GB on a phone). Files are read in pieces and the result is written to your browser’s own storage, so even long videos work; they just take longer.

    Is it free? Do I need an account?

    It is free to use and there is nothing to sign up for. There are no watermarks and no daily limits.
