Questions
About converting WEBM to MP4.
Does converting WebM to MP4 reduce the quality?
With the default settings most videos keep their original quality. If you change any video setting or set a start or end time, the video is converted with those settings and the picture can change slightly.
Can I keep the result small for sharing?
Yes. Set a lower width, for example 1280 px. A higher CRF value under the advanced settings makes the file smaller still.
Will the MP4 file have a watermark?
No. Converted files never get a watermark, free conversions included.
Where are my files stored?
On servers in the EU, and only for 24 hours. After that they are deleted automatically.
