ฟรี Animated GIF Maker

วิธีการทำงาน

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. 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. 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. 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. 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.
