How to Convert GIF to ICO

ICO is the format Windows uses specifically for icons — application icons, file type icons, and website favicons — and a single ICO file can bundle multiple sizes of the same image (commonly 16×16 up to 256×256 pixels) so the operating system can pick the right resolution depending on context. GIF's limited color palette and basic transparency support are actually reasonably well suited to simple icon graphics, since most icons don't need more than a modest color range to begin with.

This makes GIF to ICO a practical conversion for turning a simple web graphic or logo, originally saved as GIF, into a usable Windows icon file, with any transparency from the original GIF carrying over.

1. Install Turbo Batch Image Converter Pro on your Windows PC.
2. Open the app and select Batch Mode for multiple files, or Individual Mode for a single GIF.
3. Drag your GIF file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to GIF and the "To" format to ICO.
5. Click Convert. ICO files are written to the output folder, fully offline.

• 100% offline — your images are never uploaded anywhere
• Bulk conversion of entire folders, including sub-folders, in one click
• Preserves transparency from the original GIF in the resulting icon
• Produces standard Windows ICO files for icons and favicons
• Multi-core processing for fast handling of large batches
• Option to delete original GIF files automatically after conversion
