What This Tool Does
This tool loads an ICO image directly in your browser, presents an interactive crop overlay with draggable handles, and converts the selected area to a GIF file. No server upload is required. The full workflow — loading, cropping, and GIF encoding — runs entirely in client-side JavaScript using the HTML5 Canvas API. ICO files are decoded by drawing them to an offscreen canvas, ensuring complete pixel data is available before the crop overlay is drawn. The output is a GIF encoded using a median-cut color quantization algorithm to reduce the image to GIF's 256-color palette while preserving maximum visual quality.

Frequently Asked Questions
GIF (Graphics Interchange Format) is a widely supported image format limited to 256 colors, making it ideal for simple graphics, logos, and illustrations. ICO files are Windows icon containers. Converting a cropped ICO region to GIF produces a compact, universally compatible file suitable for web use, email, and legacy systems.
Yes — the tool provides an interactive crop overlay on the source image. Drag the corner and edge handles to define exactly which portion of the ICO you want in the output GIF. Click Preview Crop to see the result before downloading.
No. All processing — loading, cropping, and GIF encoding — happens entirely in your browser using JavaScript and the HTML5 Canvas API. Your image never leaves your device.
GIF supports a maximum of 256 colors. The tool uses an optimized median-cut color quantization algorithm to reduce the cropped image to a 256-color palette with minimal visible quality loss. Since ICO icons typically use flat colors, GIF results are usually excellent.
The tool is limited by your browser's available memory. ICO files are typically small (16×16 to 256×256 px), so processing is fast on all modern browsers.
Click the Start Over button that appears after loading an image. This clears the current file and resets the crop area so you can load a new ICO.
