It's for the camera, not the browser, and it looks like you can change back to h.264 and JPG [1]: > If you’re currently running iOS 11 beta 1, you can verify this by switching between the High Efficiency and Most Compatible formats under iOS Settings → Camera → Formats. Under the High Efficiency format, images will be saved as HEIC and movies as an HEVC .mov file. Under Most Compatible, images will be saved as JPGs and movies as an h.264 .mov file.
