How does the in-browser Video to GIF converter work?

It runs a compiled WebAssembly build of FFmpeg directly inside your browser. Your video files are processed on your local machine using hardware-accelerated CPU threads without uploading megabytes of video data to remote servers.

Can I remove background or green screen from video clips?

Yes! Enable the 'Chroma Key' toggle, select green, blue, black, white, or pick any hex color, and adjust color similarity. Our engine will make solid background pixels 100% transparent.

What video formats and limits are supported?

It supports standard MP4, MOV, and WebM video formats up to 50MB. Since all processing is local, there are no conversion queue wait times, no watermarks, and no sign-up requirements.

FAQ

Video to GIF FAQ

Q1What is Video to GIF?

Video to GIF conversion transforms video files like MP4 and MOV into animated GIF images. GIF (Graphics Interchange Format) is a widely-used animated image format for social media, messaging apps, and web design. This tool is powered by FFmpeg WebAssembly — all conversion happens locally in your browser with no server uploads. It supports green screen removal, custom frame rate and max width, and transparent background GIF output.

Q2How does green screen transparency work?

Using FFmpeg's ColorKey filter, background pixels matching target chroma colors are mapped to transparent alpha values with optimized 2-pass palette quantization.
