HEIF to ICO Conversion

HEIF (High Efficiency Image File Format) is the standard image format for Apple devices. It offers advanced compression, allowing for high-quality images at roughly half the file size of a JPEG. It supports features like transparency and image sequences.


ICO is a file format specifically designed for computer icons in Microsoft Windows. An ICO file can contain multiple images at different sizes and color depths, allowing the icon to scale appropriately across the interface.

Frequently Asked Questions

HEIF files are high-resolution photos (typically 3000×4000 to 4000×6000 pixels) designed for photography, while ICO format is specifically designed for tiny icons (16×16 to 256×256 pixels) for favicons and Windows application icons. Converting high-resolution HEIF to ICO involves extreme downscaling that discards 99%+ of your image data. Converting HEIF to ICO creates a multi-resolution icon container with embedded sizes drastically downscaled from your photo source. This conversion only makes sense if your HEIF contains logo/icon artwork (unusual - HEIF is for photos, not graphics) that you need to deploy as website favicons or Windows application icons. The extreme resolution reduction (from potentially 4000×3000 HEIF to 256×256 maximum ICO) means virtually all detail is lost. For photographic HEIF content, this conversion is completely inappropriate - ICO is for icons, not photos. Only convert HEIF to ICO in the rare case you photographed logo artwork for icon deployment.
