HEVC compared with other codecs

No codec wins at everything. HEVC compresses well and plays on almost any recent device; AV1 compresses a little more and is royalty-free; H.264 still works everywhere.

Key points

  • HEVC needs about half the bitrate of H.264 for similar quality.
  • AV1 compresses a bit more than HEVC and is royalty-free, but encodes more slowly and fewer older devices support it.
  • VVC is the most efficient, but in 2026 almost nothing plays it yet.
  • To share with anyone, H.264; to archive or for 4K/HDR on recent devices, HEVC or AV1.

Bitrate needed for similar quality (H.264 = 100)

  • H.264 / AVC 100
  • VP9 ≈ 65
  • HEVC / H.265 ≈ 50-60
  • AV1 ≈ 40-45
  • VVC / H.266 ≈ 30
Less is better. Average values from published comparisons; actual savings depend on content, resolution and encoder.

HEVC vs H.264

The most useful comparison, because these are the two codecs you will find in almost every file. In the reference study by Ohm, Sullivan et al. (IEEE, 2012), HEVC needed 35 % less bitrate by PSNR and 49 % less in subjective viewer tests. Later JCT-VC/BBC tests averaged 59 %, and 64 % at 4K: the higher the resolution, the bigger the advantage.

The trade-off: H.264 plays on absolutely everything, including browsers and devices from 2010, with no licensing hurdles on Windows. If you send a video without knowing the recipient's device, H.264 is still the safe bet.

VP9 and VVC

VP9 is Google's open codec (2013), AV1's predecessor. It compresses a little less than HEVC and is used mostly on YouTube and Android. VVC (H.266) is HEVC's successor: around 50 % more efficient according to JVET tests, with tools for 8K, 360-degree video and screen content. Device rollout has just begun with some 2025-2026 phone chips.

Which one should you choose?

Depending on what you want to do

Archive your videos

  • 10-bit HEVC with x265 (CRF 20-24)
  • AV1 if your devices play it

Share with anyone

  • H.264 in MP4
  • HEVC if you know it's an iPhone or a recent TV

Live streaming

  • H.264 for maximum compatibility
  • AV1 or HEVC with NVENC if the platform accepts it

Plex or Jellyfin server

  • HEVC: good compression and TV support
  • Avoid transcoding: pick what your clients play

Frequently asked questions

Is HEVC better than H.264?

For compression, yes: at the same quality it needs 35 % to 50 % less bitrate depending on the study. For compatibility H.264 wins; every device from the last fifteen years plays it.

Is AV1 better than HEVC?

AV1 compresses slightly more and is royalty-free, which is why YouTube and Netflix use it. HEVC has wider support in TVs, cameras and Blu-ray, and encodes faster. For your own videos, both are fine if your devices play them.

What is VVC?

VVC or H.266 is HEVC's successor (2020). It compresses around 30-50 % better, but in 2026 almost no consumer device plays it yet.
