GIF Maker — Create Animated GIFs Privately in Your Browser
Upload images, set the frame delay and loop count, then generate an animated GIF entirely in your browser. Your photos are never uploaded to any server. Preview the animation in real time and download the result.

How the GIF Maker Works
This tool creates animated GIFs entirely in your browser using the GIF89a encoding format. When you upload images, they are read locally using the FileReader API — nothing is sent to any server. Each image is drawn onto an HTML5 Canvas at the specified output width (maintaining aspect ratio), and the pixel data is encoded into GIF frames with the delay you set. The result is a downloadable animated GIF file.
GIF Specifications
Format: GIF89a with animation extension
Color Depth: 256 colors per frame (8-bit palette)
Frame Delay: 20ms to 5000ms per frame
Loop Options: Infinite or fixed number of loops
Each frame is quantized to 256 colors using median-cut color quantization. For best results, use images with similar dimensions and color palettes.
Privacy and Security
Your images are processed entirely within your web browser using JavaScript and the Canvas API. No image data, pixel data, or file metadata is ever transmitted to any server. The generated GIF exists only in your browser's memory until you download it. This makes the tool completely safe for creating GIFs from personal photos, confidential screenshots, or any sensitive imagery.
Tips for Best Results
Use images of the same dimensions for smooth animations. Lower frame delays create faster animations (100ms = 10 FPS, 200ms = 5 FPS). Keep frame counts reasonable — more frames mean larger file sizes. If your GIF is too large, reduce the output width or the number of frames. Simpler images with fewer colors produce smaller, cleaner GIFs.
