Complete Guide: ICO to HEIC Converter
Everything you need to know about using this tool effectively
The ICO to HEIC Converter transforms ICO (icon) files into HEIC (High Efficiency Image Container) format. ICO files contain multiple icon sizes packed into a single file, while HEIC is Apple's native image format with excellent compression. The tool renders your ICO to a canvas and exports it as HEIC entirely in the browser, so your image never leaves your device.
This tool reads your ICO file, renders it to a canvas at the largest embedded size, and exports the result as HEIC format. HEIC uses the HEVC codec for efficient compression. This is useful for extracting icon graphics in Apple's native format for use in iOS or macOS applications.

ICO files contain multiple sizes. The tool renders from the largest embedded size for the best output quality.
HEIC is primarily supported on Apple devices. Use PNG or JPG for broader cross-platform compatibility.
ICO files typically have transparent backgrounds. HEIC does not support transparency, so the background will be white.
For creating iOS app icons, consider converting to PNG first, which natively supports transparency.
Which size from the ICO file is used?
The tool renders from the largest size embedded in the ICO file to provide the best possible output quality.
Is my image uploaded to a server?
No. All processing happens in your browser using the Canvas API. The image never leaves your device.
Will the ICO transparency be preserved?
No. HEIC does not support alpha transparency. Transparent areas in your ICO will be filled with a white background.
Can Windows open HEIC files?
Yes, on Windows 10 and later with the HEIF Image Extension from the Microsoft Store. macOS and iOS support HEIC natively.
Can I convert multiple ICO files at once?
Yes. Upload multiple files and the tool converts all of them.
