Why convert MOV to GIF?
Two kinds of MOV usually become GIFs. iPhone clips, such as a pet doing something funny or a reaction, are shared as GIFs in group chats and on forums. QuickTime screen recordings on a Mac are turned into GIFs to show a bug, a feature or a how-to step in a ticket, README or help article.
iPhone videos are often HEVC in 4K at 30 or 60 fps, far more than a GIF needs. The tool scales the frames down and samples them at the rate you choose, so a 4K clip becomes a small, light GIF. For screen recordings, a lower frame rate (8–10 fps) keeps text crisp and the file small, because most of the screen does not move.
HEVC decoding relies on your browser and device: recent Macs, iPhones and most Windows PCs with hardware HEVC support can read it. If yours cannot, convert the clip with MOV to MP4 first. Live Photos can also be saved as a video from the iPhone Photos app and converted here.
