GIF Maker

Make an animated GIF from a handful of photos, screenshots or drawings — a product turning around, a before-and-after, a short sticker or a step-by-step demo. Choose the images, set how long each one stays on screen, and the GIF is built in your browser with a proper colour palette for every frame. Your images are never uploaded.

How to use this tool

1. Choose the images in the order they should play (or sort them by file name).
2. Set the time per frame — 500 ms is a calm slideshow, 100 ms is smooth animation — and the width.
3. Decide how images of a different shape are handled, the background colour (or transparent), and the number of colours.
4. Optionally add a boomerang or limit the number of loops, then press Calculate and download the GIF.

Formula

Loop length = number of frames × time per frame

Each frame is reduced to at most 256 colours (GIF's limit) with its own palette, so photos keep their colours. Dithering mixes neighbouring colours to hide banding in skies and gradients, at the cost of a larger file. GIF stores delays in hundredths of a second, and browsers treat delays under 20 ms as 100 ms.

Example

8 photos at 250 ms each loop every 8 × 0.25 = 2 seconds. With boomerang, the frames play 1–8 and then 7–2, giving 14 frames and a 3.5-second loop that ends where it started.
