HEIC (High Efficiency Image Container) uses lossy or lossless encoding and is best for Apple device photos — iPhone and Mac default format with excellent compression efficiency. ICO (Windows Icon) uses lossless (multiple sizes) encoding and excels at favicons and app icons — standard format for website bookmarks and Windows application icons. Converting between them lets you take advantage of each format's strengths — for example, using a compressed format for sharing and a lossless format for editing. All conversion happens locally in your browser with no file size limits.
The converter generates a multi-resolution ICO containing 16x16, 32x32, 48x48, and 256x256 pixel versions. Windows picks the appropriate size automatically based on where the icon is displayed.
Yes. Rename the output to favicon.ico and place it in your site's root directory. Modern browsers also accept PNG and SVG favicons, but ICO remains the most universally supported format.
ICO is a container format that holds multiple image sizes in one file. Windows requires ICO for desktop icons and taskbar pins because it needs different resolutions for different display contexts.
Yes. The alpha channel from your HEIC source is preserved in the ICO output, so your icon will have clean transparent edges.
The converter scales your image to fit a square canvas. If the aspect ratio does not match, the image is centered with transparent padding on the shorter sides.
