Frequently asked questions

Why would I convert AV1 away?

AV1 is efficient but newer devices and some players cannot decode it. H.264 remains the safest compatibility target.

Which browsers can run this?

The browser must decode AV1 and encode H.264. Safari supports only part of this, so Chrome or Edge are recommended.

Will the file be larger?

Likely yes — H.264 is less efficient than AV1, but it trades size for universal playback.
