PNG, JPG, WebP, GIF, SVG · one file · at least 512×512 recommended
Tips
- Use the frame selector slider to capture the exact frame you want from an animated GIF.
- GIF graphics rely on an 8-bit color table, which may show color banding when rendered across smooth gradients.
- Because GIF transparency is binary 1-bit, transparent edges will appear aliased compared to 8-bit alpha PNG sources.
How to use it
- 1 Upload or drag your GIF file into the converter.
- 2 Select the desired animation frame using the frame slider.
- 3 Choose the target icon resolutions you want bundled into the ICO container.
- 4 Save and download the generated ICO file to your device.
What you should know
Web browsers and Windows environments rely on the ICO format to display desktop shortcuts and site favicons across distinct resolutions. While modern web design often starts with vector or full-color raster formats, legacy graphics and animated brand assets frequently exist as GIFs. The GIF format restricts color to an 8-bit indexed palette of 256 colors and supports only binary 1-bit transparency, meaning pixels are either fully opaque or completely clear. Converting a GIF to an ICO file packages these graphics into a standardized container capable of storing multiple static icon sizes, ensuring compatibility with traditional desktop interfaces and older web platforms.
This converter decodes your source GIF locally in the browser, isolating individual frames so you can select the best still image for your icon. The engine rescales the selected frame across common dimensions, such as 16x16, 32x32, and 48x48 pixels, before embedding them into a single ICO file. Because the ICO format cannot play animated sequences, any temporal animation data and looping metadata are omitted. The tool preserves existing indexed transparency boundaries without modifying your original files on a remote server, delivering a compact icon ready for immediate website favicon integration or desktop software packaging.
Frequently asked questions
Will the generated ICO file be animated?
No, standard ICO files do not support frame-by-frame animation. The converter extracts one static frame of your choice from the GIF and packages it into the icon container.
Does the conversion maintain transparency from the GIF?
Yes, 1-bit transparency is preserved. However, because GIF transparency lacks smooth alpha blending, semi-transparent edges will render with sharp, binary transitions.
Are my GIF files uploaded to an external server?
No, all file decoding, frame selection, and ICO encoding take place locally inside your browser tab using native web APIs.
