Video compressor

Reduce video file size with adjustable quality.

The video engine is downloaded from this site only when you start. Processing can be CPU- and memory-intensive. Keep this tab open; cancellation stops the worker and releases its memory.

About Video compressor

Make a video easier to store or share by changing its compression settings. The video runtime loads when needed; long clips and large frames can require substantial processing time and memory.

Steps, and limitations

How to use it

  1. Select a video that the runtime can decode.
  2. Choose compression settings and start the job.
  3. Keep the tab open, then download and play the exported file to check it.

Things to know

  • Stronger compression can reduce detail or introduce artifacts. Test a short clip before a large batch.
  • Supported containers and codecs depend on the bundled runtime; not every video is compatible.
