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
  • Loop-friendly output suited to autoplay and muted playback
  • Batch conversion across many GIFs
  • Your GIF files are processed on your own server and never uploaded anywhere

What you can do

  • Cut page weight by replacing a heavy GIF with a looping WEBM
  • Get a GIF onto a platform that accepts video but not animated images
  • Recover a usable master from an animation that only survives as a GIF

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.
