How to Convert TIFF 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. TIFF is rarely the ideal source for icons, since icons are typically displayed very small and benefit from simple, high-contrast source images rather than the fine detail and high color depth professional TIFF files capture.

That said, converting a TIFF logo or graphic to ICO is sometimes useful when a design originally created in a print or archival workflow needs to become a usable icon, with the conversion process handling the format change and packaging it into the ICO container Windows expects.

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 TIFF file.
3. Drag your TIFF file or folder into the app window, enabling recursive folder scanning if needed.
4. Set the "From" format to TIFF and the "To" format to ICO.
5. Click Convert. ICO files are written to the output folder, fully offline.
