What happens to your file
WebM files are common for website video, HTML5 players, transparent overlays, but not every app or device opens them. GIF is the better choice for reactions, memes, short loops in chats, emails and docs. Spool converts WebM to GIF with FFmpeg — real decoding and encoding, not a renamed file extension.
Built for quality GIFs. We scale with the Lanczos filter, generate a palette optimized for your exact clip and dither it, which produces richer color and fewer artifacts than single-pass converters. Choose the start time, length (up to 60 s), width and frame rate.
