H.264 vs H.265
Which should you use?
Quick verdict
Use H.264 (AVC) for maximum compatibility - it plays on nearly every device, browser, and editor with no setup. Use H.265 (HEVC) for 4K and to cut file size by roughly 40-50% at the same quality, where your target devices support it.
H.264 (AVC) and H.265 (HEVC) are both widely used video compression standards, but they trade off differently. H.264 has been the default since 2003 and plays almost anywhere with no setup. H.265 arrived in 2013 and compresses far more efficiently, which matters most for high-resolution and high-bitrate footage.
The core choice is compatibility versus efficiency. H.264 wins on reach and easy encoding; H.265 wins on file size and 4K quality, but needs more processing power, has patchier support (especially in web browsers), and carries more complex patent licensing.
At a glance
| Property | H.264 | H.265 |
|---|---|---|
| File size (same quality) | Larger (baseline) | ~40-50% smaller |
| Compatibility | Universal | Limited (esp. browsers) |
| Encode/decode load | Lighter | Heavier |
| Best resolution | 1080p, basic 4K | 4K and 8K |
| Hardware support | Everywhere | Newer devices |
| Licensing | Simpler, mature | More complex patents |
Choose H.264 when
- You need a file that plays on any device, browser, or platform
- You are sharing video on the web or older hardware
- You want fast encoding with minimal CPU/GPU cost
- Compatibility matters more than saving storage
Choose H.265 when
- You are working with 4K or 8K footage
- You want to cut file size and bandwidth at the same quality
- Your target devices and players support HEVC
- Storage or streaming costs are a priority
