How It Works

1. Drop or select a video file (MP4, WebM, MOV, AVI, MKV)
2. Set trim range, FPS, resolution, and dithering options
3. Click "Convert to GIF" — FFmpeg.wasm runs entirely in your browser
4. Download your animated GIF

Why Use This Tool?

AI chatbots like ChatGPT, Claude, and Gemini cannot convert your video files to GIFs. They cannot read binary video data, decode frames, optimize color palettes, or generate valid GIF files. This tool uses FFmpeg.wasm — the same engine that powers professional video processing — to deliver pixel-perfect GIF conversion directly in your browser.

What video formats are supported?

Input: MP4, WebM, MOV, AVI, MKV, FLV (any format FFmpeg supports). Output: Animated GIF.

What is the best FPS setting?

10 FPS is the best balance of smooth animation and small file size. Use 5 FPS for smaller files (simple motions), 15-20 FPS for smoother playback. 30 FPS matches original video but creates large files.

How does dithering affect quality?

Bayer dithering (default) gives the best balanced result. Floyd-Steinberg produces finer detail but larger files. "None" creates posterized solid-color GIFs, great for pixel art or diagrams.

Is there a file size limit?

Browser memory is the only limit. Files under 500MB work best on modern devices. Longer videos with higher FPS/resolution create larger GIFs.

Can I make a GIF from only part of a video?

Yes! Use the Start Time and End Time options to select a specific segment. A 2-5 second clip usually makes the best GIF.

Why can't AI chatbots do this?

LLMs (ChatGPT, Claude, Gemini) are text models. They cannot read binary video file structures, decode video frames, perform color quantization, or write the GIF format. Video processing requires deterministic algorithms, not text generation.
