01 · SOURCE & SETTINGS

Set up video compression

Up to 60 MB, 60 seconds and 4K. Compression runs in your browser.

The tool keeps the original proportions and does not upscale. Encoded size varies by source and browser.

Compare the files

Choose a video to see the original and compressed file sizes.

Compress a video and compare the actual file size

Choose an output format that the destination accepts, set a smaller long edge and lower the video bitrate. Keep the original until you have checked the exported file on the device or service where it will play.

Steps

  1. Open a supported clip

    Choose an MP4, MOV or WebM the browser can decode. Confirm that the clip opens and note the original file size and dimensions before changing the settings.

  2. Set the size, bitrate and audio

    Try the 1280 px long edge and Balanced bitrate first. Use 960 or 640 px when the video will play in a small space. Leave audio on when speech or music matters. For a silent clip, switch it off before exporting.

  3. Review the new file

    Compare the measured sizes, play the export and check fast movement, small text and the primary audio. Re-encode from the original when you want to try another combination, because each extra lossy encode can remove detail.

File and export limits

The source can be up to 60 MB and 60 seconds, with up to the pixel count of a 3840 × 2160 frame. Output is capped at 48 MB. Smaller clips stay at their current dimensions. Exact file size and codec availability depend on the input and browser.

Common questions

Why did my export get bigger?

The original may already use a low bitrate or an efficient codec. Try a lower bitrate or smaller dimensions, then compare the result again.

Which format should I choose?

Start with MP4 if the destination requires it. Use WebM when supported by both the browser encoder and the playback destination.
