GIF was designed when 256-colour displays were standard. Each frame uses a palette of up to 256 colours selected from the source image. For illustrations and flat-colour graphics this is plenty. For photographs with millions of colours, the palette causes visible "colour banding" — smooth gradients become stepped. This is why photographic GIFs look worse than an equivalent JPEG. For photo-quality animation, use animated WebP or MP4 instead.

Frequently Asked Questions
Everything you need to know about this conversion tool.
Up to 30 frames per GIF. Each frame should be the same dimensions for best results — mismatched sizes are automatically padded to the largest frame size.
100ms (10 fps) works well for smooth animations. For slow slideshow effects use 500–1000ms. The minimum delay for most browsers is 20ms.
GIF is limited to 256 colours per frame. Photos with rich gradients will show colour banding. For photographic content, consider animated WebP or MP4 output for better colour fidelity.
Yes — use the drag-and-drop reorder interface in the upload step to arrange frames before converting. The order shown is the order they appear in the animation.
By default yes (loop count 0 = infinite). Set loop count to 1 for a one-shot animation that plays once and stops, or any other number for a specific repeat count.
Output GIFs are capped at 1280px on the longest edge to keep file sizes manageable. For large-format animation, use the MP4 output option instead.

GIF Animation Guide: Frame Rates, Palettes and File Size Optimisation
Animated GIFs have outlasted every prediction of their demise. Despite their 1987 origins, GIFs remain the universal format for short looping animations across social media, messaging apps, and documentation. Here is everything you need to know to create them well.
Understanding GIF's 256-Colour Limitation
Choosing the Right Frame Delay
Frame delay is the time each frame is displayed before advancing to the next, in centiseconds (1/100 of a second). 10cs (100ms) = 10 fps — a natural animation speed. 5cs (50ms) = 20 fps — smoother but larger files. 50cs (500ms) — a slow slideshow. Note that many browsers enforce a minimum frame delay of 2cs (20ms) — GIFs that specify less than 2cs are displayed at a browser-dependent rate, usually 10fps.
GIF vs Animated WebP vs MP4 for Web Use
Use GIF for universal compatibility — every platform supports it. Use Animated WebP when you control the environment (modern browsers only) for 50–80% smaller file sizes with full colour. Use MP4 (H.264) for the smallest file size and the smoothest playback — an autoplaying, muted video tag is 10–20x smaller than an equivalent GIF and is the recommended approach for large animations on web pages.
Gifsicle Optimisation: How It Reduces File Size
Gifsicle is the industry-standard GIF optimiser. It analyses frame-to-frame differences and encodes only the changed pixels in each frame (delta encoding) rather than full frames. It also optimises the LZW compression table and removes redundant metadata. O3 optimisation (which we use) applies the most aggressive delta and palette deduplication passes, typically reducing file sizes by 20–40% compared to unoptimised output.
Tips for Smaller, Sharper GIFs
Keep dimensions as small as possible — every extra pixel multiplies the file size. Use a consistent background colour across frames so delta encoding is more effective. Reduce unnecessary frames — 8–12 fps is often indistinguishable from 24 fps for simple animations. Crop tightly around the animated element. For text-heavy GIFs, ensure your source PNGs are at least 2x the GIF output size for crisp downsampled text.
