Photo to Animated GIF

Turn an ordered set of photos into a looping animated GIF.

How it works

Upload a ZIP of photos, choose frame dimensions, timing and fit, and download an animated GIF. A shared deterministic encoder uses a fixed 256-color palette, with no external service.

Archive entry order is playback order. Each image is auto-oriented, centered, resized and flattened on the chosen background.
Frame duration is rounded to the GIF time unit of 10 milliseconds. The limit is 24 frames and 12 million total frame pixels.
GIF uses a fixed RGB332 palette (256 colors), no transparency and no adaptive photographic quantization. File sizes may be larger than optimized GIF encoders.
