Recommendation
Web playback with compatibility first: H.264 in MP4 — largest files but plays everywhere. AV1 would cut size substantially at the cost of much slower encoding and patchier hardware decode.
How the Video Codec Comparison works
- Choose where the video is going; the answer differs sharply between a website and an archive.
- Set your priority — compatibility, size, and encode speed genuinely trade against each other.
- Read the trade-offs before committing, particularly hardware decode support on the devices your audience uses.
FAQ
Why is H.264 still the default?
Because it plays on essentially everything, including old devices, and hardware decoders are universal. Newer codecs produce smaller files but narrow your audience or push decoding onto the CPU.
Is AV1 worth it yet?
For large-scale streaming where bandwidth cost dominates, yes. For a small site, the encoding time and the devices lacking hardware decode usually outweigh the savings.
What about HEVC licensing?
HEVC's patent situation is famously complicated, with multiple licensing pools, which is a large part of why AV1 exists as a royalty-free alternative. It is a business question as much as a technical one.

Video Codec Comparison weighs hardware decode support alongside file size, because a smaller file that drains a phone battery is not a win.
