GIF to WEBM
Convert an animated GIF into WebM video. This is usually a large win: real video codecs use motion compensation, so the same animation typically lands 5-20x smaller than the GIF and looks better, having escaped GIF's 256-colour ceiling. WebM plays in every modern browser, but not in most desktop players or on TVs. Runs on your own Vistalyth Tools instance. Files never reach a third party.
Features
- Frame timing preserved, including variable per-frame delays

What you can do

Self-hosted. Your files never leave your network.
Vistalyth Tools runs entirely on your own infrastructure. Files processed with GIF to WEBM are never uploaded to third-party servers. Deploy a single Docker container and process files with full privacy, no watermarks, and no usage limits. Open source under AGPL-3.0.
Frequently asked questions
- Will it still loop?
- The video carries the same frames and timing. Looping then becomes a playback setting: the loop attribute in HTML, or the platform's own toggle.
- What happens to GIF transparency?
- Video has no alpha channel, so transparent pixels are composited onto a solid background. Animated WebP is the better target when that transparency matters.
- Why target WEBM?
- Pick WebM for video you serve from your own pages, where you control playback and want smaller files with no licensing questions attached.
- How much smaller will it be?
- Usually 5-20x, and more on long or high-frame-rate animations. Flat graphics with little motion gain the least.
