Description

MP4 (short for MPEG-4 Part 14) files store multimedia - video, audio and subtitles. Websites frequently use them for displaying videos because the MP4 format is universally supported.
However, newer video formats, such as WebM, produce smaller file sizes with almost no quality loss. Therefore, you can free up storage by converting your videos to WebM.

Your files are automatically and irreversibly deleted from our servers at the latest after 72 hours, for conversion with an error. The files of successful conversions are deleted 24 hours after their completion. You can also manually initiate the deletion by clicking the DELETE FILES NOW button.

Sharing of User Data

Your uploaded files will not be given out or sold to anyone. Any other personally identifiable information will not be given out or sold, either.
