Hoe het werkt

GIF encoding runs entirely in your browser via gif.js — a pure-JavaScript GIF encoder with a Web Worker for performance. Your images never upload.

1
You drop multiple images
Each image is loaded into your browser's memory and decoded by the browser's built-in image decoder. They appear in the frame list in upload order.
2
Each frame is drawn to a canvas at the chosen width
Aspect ratio is preserved from the first frame. The canvas pixel data is passed to gif.js as a sequence of frames with your chosen delay.
3
A Web Worker encodes the GIF in the background
gif.js spawns a worker to encode without blocking the UI. The worker handles color quantization (reducing each frame to 256 colors) and outputs LZW-compressed GIF bytes.
4
The finished GIF is offered for download
When encoding completes, you can preview the animation and save it locally. The Blob is held only in your browser memory.

Your photos never upload anywhere. The gif.js worker runs in your browser. Suitable for personal photo collages, memes from screenshots, or sensitive content.
