What format does the output video use?

The tool produces a WebM file encoded with VP8 or VP9, depending on your browser. WebM is natively supported in Chrome, Firefox, Edge, and Opera. Safari supports WebM since version 14.1. The file plays as a looping video in all modern browsers using the HTML video tag.

Is my GIF file uploaded anywhere?

No. All processing happens entirely inside your browser using the File API, Canvas API, and MediaRecorder API. Your GIF data never leaves your device.

Why does conversion take longer for large GIFs?

Each frame must be drawn to a canvas and recorded in real time at the correct frame delay. A 100-frame GIF with 50 ms per frame takes about 5 seconds of real-time playback to record. Large GIFs with many frames or slow delays take proportionally longer.

What if my browser shows "MediaRecorder not supported"?

MediaRecorder is available in Chrome 47+, Firefox 29+, and Edge 79+. If you see this message, update your browser. Safari added MediaRecorder support in version 14.1 (2021). Internet Explorer does not support it.

Can I control the output video bitrate or quality?

The tool uses the browser default bitrate for WebM recording. For precise bitrate control or H.264 MP4 output, use FFmpeg with: ffmpeg -i input.gif -c:v libx264 -pix_fmt yuv420p output.mp4

Why is the output file larger than the GIF?

WebM captured via MediaRecorder is a lossless or near-lossless stream recorded in real time; it is not re-compressed like a hand-tuned FFmpeg encode. For maximum size reduction, run the output through FFmpeg after downloading.

Summary

This tool converts an animated GIF into a WebM video file entirely inside your browser. It uses the omggif library to decode every GIF frame, renders them onto an HTML Canvas at the correct frame delay, and captures the canvas output with the MediaRecorder API. The resulting WebM file plays in all modern browsers and can be used as a lightweight MP4-compatible looping video on websites.
