Why Convert HEIC to ICO?
While HEIC is a modern and efficient image format, ICO is a specialized format primarily used for:
- Favicons: The small icons displayed in browser tabs, bookmarks, and search results. ICO is still widely supported and often preferred for this purpose.
- Desktop Icons: Icons for applications, folders, and files on Windows operating systems.
- Legacy Compatibility: For older systems or specific software that require the ICO format for icons.
Key Features of This Converter
Versatile ICO Creation
- • **Batch Processing:** Convert multiple HEIC files to ICO simultaneously.
- • **Single Size Selection:** Choose one standard ICO size (e.g., 16x16, 32x32, 48x48, 256x256) for the output ICO file.
- • **Transparency Handling:** HEIC transparency is preserved in ICO frames that support it (typically 32-bit PNG-encoded frames within the ICO). For frames that do not, transparent areas are filled with a customizable background color.
User-Friendly Options
- • **Filename Customization:** Add prefixes or suffixes to your output ICO filenames.
- • **Download Options:** Download files individually or as a ZIP archive.
- • **Client-Side Processing:** All processing is done directly in your browser; files are not uploaded.
How to Convert HEIC to ICO
- Upload HEIC Files: Drag and drop your HEIC/HEIF images, or click to select files. The necessary encoders will load dynamically.
- Adjust Settings (Optional):
- **ICO Size:** Select the single resolution you want for your ICO file.
- **Background Color:** Choose a color to fill transparent areas for ICO frames that does not support transparency.
- **Naming:** Add a prefix or suffix for the output filenames.

Frequently Asked Questions
Will transparency from my HEIC file be kept?
Yes, for ICO frames that support it (typically 32-bit PNG-encoded frames within the ICO). For other frames (e.g., 24-bit BMP-encoded frames), transparent areas will be filled with the background color you select.
Will the ICO file be larger than the original HEIC?
Yes, almost certainly. HEIC is a highly compressed format, while ICO files often contain uncompressed or lightly compressed image frames. The ICO file size will increase with the selected size and the complexity of the image.
Can I convert Live Photos or animated HEIC files to ICO?
No. ICO is a static image format and does not support animation. If you upload a Live Photo or animated HEIC, only the static key image (first frame) will be processed and converted into the static ICO file.
Why do the encoders take time to load?
Browsers do not natively support HEIC decoding or ICO encoding. This tool uses client-side libraries (likely WebAssembly modules) to perform these complex tasks. These libraries are loaded on demand to keep the initial page load fast. The loading time depends on your internet speed and the size of the modules.
Are my images uploaded to a server?
No, all image conversions are performed directly in your web browser. Your files are not sent to any external server, ensuring your privacy and security.
