Re-encoding can change detail and file size. Inputs and outputs must fit the displayed limits; long videos need a different workflow.

Example: Convert a short MP4 clip to WEBM and verify its motion and dimensions.

Online uploads and individual outputs are limited to 4 MB. Direct conversions need no account or payment. See all limits · Conversion tutorials.
