How it works

  1. Choose one video up to 25 MB and ten minutes.

  2. Set MP4 or WebM, the maximum edge and compression value.

  3. Compare file size and playback quality before using the result.

Useful next steps

Convert video to MP4 or WebMSave a video as MP4 or WebM. Check its picture, sound and duration in the application where you plan to use the result.
Trim and rotate a videoChoose start and end times, rotate the picture and adjust volume. Review the result as one continuous video excerpt.
Convert audio to another formatCreate MP3, WAV, OGG, FLAC or M4A from a recording or a video soundtrack. Check the selected excerpt and listen to the exported file.

Two settings with different effects

A smaller edge lowers the resolution. The compression value runs from 18 for higher quality to 40 for stronger compression. Check motion, small lettering and dark transitions. A setting that works for a quiet scene can create blocks or blur during fast action.

No fixed saving is promised

Processing takes place on the server. An already efficient video can stay the same size or become larger. Compare the actual files and keep the source: recompression cannot recover lost picture information. Selecting a shorter excerpt can also reduce the amount of data you need to share.

Frequently asked questions

Does a higher value mean better quality?

For this compression setting, the opposite applies: it compresses harder and may remove more visible detail.

Is the selected scene kept in full?

The output duration is checked. Also inspect its start and end yourself to confirm the selected range is correct.
