What happens

3
What happens, and why

Pick several images and they become the frames of one GIF, in the order you picked them. Every frame shows for 500 ms and the animation loops forever. The file is assembled inside this browser and never sent to a server.

GIF stores at most 256 colours per frame. A screenshot, a logo or a drawing with few colours is stored exactly, pixel for pixel, and the badge next to the result says so. A photograph has far more colours, so it is reduced to 256 and bands, and the badge says that instead. GIF has no partial transparency either: a semi-transparent pixel becomes opaque or transparent.

The canvas is the first image’s size. An image of another size is scaled to fit inside it, aspect kept, with transparent padding around it, which resamples that frame. For frames that must stay exact, give every image the same size first; the crop tool cuts to an exact pixel size without re-encoding.

FAQ

3
Can I change the delay or the order

Yes. The box under the list sets how long every frame shows; it starts at 500 ms. Each row has up and down buttons, and can be dragged, to change the order — the GIF is made again each time. The GIF speed page changes a finished GIF’s pace without re-encoding it.

Why does my photo look grainy

GIF has 256 colours per frame. A photograph with thousands of colours is reduced to 256, which shows as banding in gradients and skin. For photographs, a video format or WebP keeps the colours.

Where do my images go

Nowhere. The GIF is assembled inside this browser, and camera metadata (EXIF, location) is not carried into it.
