Which video formats does Wallper support?

Wallper supports MP4 files (H.264 or HEVC) for live wallpapers, plus static JPG, PNG and HEIC images.

For live wallpapers, the only supported container is MP4 with an H.264 or HEVC video stream. Files in other containers — such as .mov from Final Cut Pro / iMovie / QuickTime, or .hevc raw streams — need to be converted to .mp4 first. Audio tracks are ignored, so you don’t need to strip them manually.

For static backgrounds you can use JPG, PNG or HEIC. Animated GIFs aren’t supported directly — convert them to MP4 first for smoother playback and smaller files.
