Edge webrtc H265 support

Question

Edge webrtc H265 support

K Anderson 0

In 2025, Edge announced support of webrtc H265 (HEVC) in release 136. However, that has since been removed from the release notes. Why was it removed? And is support planned for this?

Both Chrome and Safari started officially supporting webrtc H265 (HEVC) in 2025. So it might be worth putting on the roadmap.

Thanks,

Ken

Hi @K Anderson , @Yashraj Singh ,

Thank you for getting back to me—I really appreciate it.

Regarding your feedback, I recommend submitting it directly through Microsoft Edge so it can reach our product team. You can do this by following these steps:

Click the three dots in the top-right corner of Edge and select Help and feedback > Send feedback.
A pop-up will appear where you can describe your experience and, if helpful, include additional details or a screen recording.

While this may not resolve the issue immediately, your input is valuable and helps our product team prioritize future improvements. There’s a possibility that native WebRTC H.265 support in Edge may be reconsidered for upcoming plans.

I hope this information is helpful. If you need any further assistance or have additional questions, please don’t hesitate to reach out—I’d be happy to help.

Have a wonderful day!

Hi @K Anderson ,

Thank you for sharing your concerns with us.

Regarding WebRTC H.265 (HEVC) support in release 136, there is currently no official explanation or documentation from Microsoft regarding the removal of the previously published note on WebRTC H.265. Additionally, I regret to inform you that there is no publicly available roadmap, plan, or commitment confirming future support at this time.

While there are some third-party extensions available in the market that enable WebRTC H.265 (HEVC) functionality in Microsoft Edge, these are not developed or officially supported by Microsoft. You may choose to evaluate these options based on your specific requirements.

I hope this information is helpful. Should there be any updates or official announcements in the future, I will be sure to share them promptly. If you have any further questions or need additional assistance, please feel free to reach out—I would be happy to support you.

Wishing you a great day ahead!

Hi @Lizzy Dinh (WICLOUD CORPORATION)
I’m facing a similar issue. We’ve built a VMS and recently added HEVC support—it works fine on Chrome, but we’re struggling to get it working on Edge. We’ve tried multiple extensions, including the paid Microsoft HEVC extension, but nothing seems to help.

Thanks Lizzy. Yes, your response was helpful. It just didn't answer my questions. I'm not really interested in third party extensions, I'm interested in Edge's native webrtc H265 support. Specifically why it was removed from the release notes and whether support is planned. If this information isn't available publicly, it would be nice to know where/who to go next to find out/increase priority.

Thanks @Lizzy Dinh (WICLOUD CORPORATION)
I’ve done that, could you let me know if there’s a way to escalate this issue? If it’s not currently on the roadmap, I may need to ask our existing users to switch to another browser that supports HEVC over WebRTC. It would be great if this could be prioritized and added to the pipeline.

Answer 2

The current Microsoft Edge 136 web platform release notes list only “H26x codec support updates for MediaRecorder” and no longer mention “H265 (HEVC) codec support in WebRTC”. The documented change is that MediaRecorder now supports HEVC encoding and new HEVC/H.264 codec strings and containers, with HEVC availability depending on device and OS capabilities.

The context provided does not state any reason for the earlier WebRTC H.265 note being removed, nor does it document any current or planned WebRTC H.265/HEVC support in Edge. Only MediaRecorder HEVC support is described, and only for recording, not for WebRTC.

Based on the available documentation, no official explanation is published for the removal of the WebRTC H.265 item from the release notes, and there is no documented plan or commitment for WebRTC H.265 support in Edge beyond what is described for MediaRecorder.
