How to Convert MP4 to GIF (with Perfect Color Palettes)

To convert an MP4 to a high-quality GIF, use Zro7 MP4 to GIF. It runs FFmpeg's two-pass palette workflow (palettegen + paletteuse) in your browser, producing GIFs with vivid colors and no banding — instead of the muddy 256-color mess you get from a naive one-pass conversion. Nothing is uploaded.

Why GIFs usually look bad

GIF only supports 256 colors per frame. A one-pass conversion picks a generic web-safe palette that fits nothing well, so gradients band and skin tones turn gray. FFmpeg's palettegen filter analyzes your specific video and builds a custom 256-color palette; paletteuse then applies dithering to hide the color quantization. Same file size, dramatically better result.

Recommended settings

• Framerate: 15 fps for most content (source 30/60 fps looks fine). Higher = larger file.
• Width: 480–720 px; GIFs balloon fast at 1080p.
• Dither: Bayer scale 5 for smooth gradients; Floyd-Steinberg for detail-heavy scenes.

Steps

1. Open MP4 to GIF.
2. Drop the video (MP4, MOV, WebM all fine).
3. Set start/end timestamps and output width/fps.
4. Click Convert. Two-pass palette runs automatically.
5. Download the GIF.

When to skip GIF entirely

For any platform that supports it (Slack, Discord, most modern web CMSes), a short muted MP4 or WebM is 5–20× smaller than the equivalent GIF and looks better. GIF only wins when the destination truly requires it (email newsletters, legacy forums, Reddit inline previews).
