What is a TIFF (Tagged Image File Format) file?

TIFF is a high-resolution raster image format created by Aldus Corporation under the .tiff extension. While perfect for large-format printing, web browsers and Windows operating systems cannot display TIFF files as shortcut icons or website favicons.

Why convert TIFF to ICO?

Converting a high-resolution TIFF logo into a Windows ICO container extracts the artwork and packages it into standard icon dimensions (including 16x16, 32x32, 48x48, and 256x256 pixels) with clean transparency. This creates ready-to-use desktop shortcuts and browser favicons from your master brand artwork.

Developed by: Aldus Corporation (now Adobe Systems)

Initial Release: Autumn 1986

What is an ICO (Windows Icon) file?

ICO is an icon resource container format developed by Microsoft for Microsoft Windows. Saved with the .ico extension, it encapsulates multiple bitmap images at varying pixel resolutions (such as 16x16, 32x32, 48x48, 64x64, 128x128, and 256x256 pixels) and color depths (including 32-bit RGBA with alpha transparency). It also serves as the international standard for website favicons.

How to open and use an ICO file?

Windows displays ICO files natively as desktop, folder, and application shortcut icons. Web designers place favicon.ico files in the root folder of websites to display tab branding across Google Chrome, Safari, Firefox, and Edge. Image editors like GIMP also provide full ICO reading and editing support.

Our local browser tool allows you to convert and generate ICO icons directly on your computer without uploading files to any external server.
