Convert WebM video files to animated GIF online. Browser-only processing — no upload, no watermark.
WebM is an open video format developed by Google, built around the VP8 or VP9 video codec and Opus audio. It's the format your browser uses when you record video with the MediaRecorder API, and it's the default output of many screen recording tools including OBS Studio's browser source recordings and Chrome's built-in screen capture. Loom, some Zoom export options, and many browser-based recording tools default to WebM as well.
WebM is excellent for web streaming but has limited support outside browsers — WhatsApp, Discord, most email clients, and many CMSs don't render WebM inline. Converting WebM to GIF gives you the universal compatibility you need to share the clip anywhere.
GifSmith's WebAssembly FFmpeg runtime handles both VP8 and VP9 WebM files natively. You don't need to install any codecs or additional software. Drop the WebM file onto the forge and GifSmith decodes it locally — no server required, no upload wait. This is especially convenient for WebM files from screen recording sessions that you want to turn into quick shareable GIFs for documentation or bug reports.
OBS recordings: Streamers and content creators who capture in WebM via OBS can extract highlight clips as GIFs for sharing on Twitter/X, Reddit, or Discord.
Browser API recordings: Developers testing MediaRecorder-based features produce WebM files that need converting to GIF for GitHub issues or documentation.
Loom clips: Downloaded Loom recordings often arrive as WebM and need GIF conversion for embedding in docs or email.
Chrome screen captures: Chrome's built-in screen recorder exports WebM by default.
Your WebM file is processed entirely inside your browser. GifSmith decodes the VP8/VP9 stream, trims to your selected clip window, applies palette optimization, and renders a compact GIF. All of this happens on your machine — nothing is ever uploaded to an external server. The download is instant and watermark-free.
