Convert ICO to GIF — Free Online Converter

ICO (Windows Icon) is a multi-resolution icon container used for Windows application icons and web favicons. GIF (Graphics Interchange Format) is a widely supported web image format with 256-color palette support and binary transparency. Converting ICO to GIF produces a lightweight web image from an icon file, suitable for displaying icon previews in web contexts where GIF is the expected format.

Since ICO icons typically use limited color palettes and small dimensions, GIF's 256-color restriction is often not a limitation. Simple application icons and favicons frequently use fewer than 256 colors, making GIF a natural fit for icon image distribution.

GIF is universally supported in web browsers, email clients, forum software, and legacy CMS platforms. When you need to embed icon images in HTML emails, wiki pages, or forum posts, GIF provides guaranteed display compatibility. Unlike ICO, which only renders properly in browsers as favicons or in Windows shell, GIF displays inline in any web context.

GIF's binary transparency support is sufficient for most icon images, which typically have hard-edged (non-anti-aliased) transparency boundaries. Simple icons with flat colors and hard edges convert to GIF with no visible quality loss.
