H.264 vs H.265 vs AV1: Video Codec Comparison
Video codecs determine compression efficiency, quality, and compatibility. Compare the three dominant codecs for streaming and distribution.
Key Takeaways
- H.264 is supported on virtually every device made in the last decade.
- H.265 achieves 30-50% better compression than H.264 at equivalent quality.
- AV1 matches or exceeds H.265 compression with no patent fees.
- Use H.264 for maximum compatibility.

H.264 (AVC): The Universal Standard
H.264 is supported on virtually every device made in the last decade. Hardware encoding and decoding is available on all modern CPUs and GPUs. It's the safe choice when compatibility is the priority.
H.265 (HEVC): Better Compression
H.265 achieves 30-50% better compression than H.264 at equivalent quality. A 1 GB H.264 file becomes 500-700 MB in H.265. The trade-off is slower encoding and patent licensing costs that limit browser support.
AV1: The Open Future
AV1 matches or exceeds H.265 compression with no patent fees. It's backed by Google, Netflix, Amazon, and others. Hardware decoding is available on newer devices (2020+). Encoding is very slow but improving rapidly.
Comparison
| Feature | H.264 | H.265 | AV1 |
|---|---|---|---|
| Browser support | Universal | Safari only | Chrome, Firefox |
| Hardware decode | All devices | Most modern | 2020+ devices |
| Compression | Baseline | +30-50% | +35-55% |
| Encoding speed | Fast | Medium | Slow |
| License | Licensed | Licensed | Royalty-free |
Recommendation
Use H.264 for maximum compatibility. Use H.265 for Apple devices and storage savings. Use AV1 for web streaming where you control the player.
