HEIC to ICO Converter

What HEIC to ICO conversion does

Convert a HEIC photo from your iPhone into a Windows ICO icon directly in your browser. Because ICO is a container of icon sizes rather than a single image, you get either one chosen size or the default multi-size package covering 16, 32, 48, 64, 128, and 256 px, all generated from that one photo.

How to convert HEIC to ICO

1. Choose a HEIC file.
2. Pick a single icon size, or leave the default multi-size package selected.
3. Select Convert & download.
4. Save the .ico file from your browser downloads.

Why use this conversion

Windows icons, desktop shortcuts, and favicons need an actual .ico file, which a phone photo saved as HEIC can't provide on its own. Converting turns any HEIC image into a real, multi-resolution icon package ready to install or upload.

Transparency and output quality

Each embedded size keeps the alpha channel from the decoded HEIC image intact — this is a real ICO container (ICONDIR plus one entry per size), with each size stored as genuine PNG-compressed image data, not a renamed bitmap. Each icon entry is PNG-compressed individually, so converting a HEIC photo to a single icon size keeps the file small; picking the default multi-size package is larger since it bundles six separately-encoded images from that same source photo.

Privacy and local processing

• Processing occurs locally in the browser.
• Files are not uploaded to Looty Tools for conversion.
• Converted files remain on your device.

Limits and known issues

• Input: HEIC/HEIF (.heic, .heif) only, up to 25.0 MB and 8,192 px per side.
• Every icon size is produced by resizing your HEIC photo to a square canvas, so a typical non-square iPhone photo will be stretched or cropped to fit — start from an already-square source for a clean icon.
• A multi-image HEIC — a burst or Live Photo — produces one ICO package per captured frame, delivered as a ZIP when there's more than one; every decoded image is kept.
• Metadata is not preserved in the downloaded file.

HEIC to ICO FAQ

Why convert HEIC to ICO?

Windows icons, desktop shortcuts, and favicons need an actual .ico file, which a phone photo saved as HEIC can't provide on its own. Converting turns any HEIC image into a real, multi-resolution icon package ready to install or upload.

Can I generate a multi-size ICO?

Yes. The ICO output defaults to a multi-size package covering 16, 32, 48, 64, 128, and 256 px generated from your HEIC photo, or you can pick a single size from the dropdown.

Is this a real ICO file, or a renamed image?

A real ICO container (ICONDIR plus one entry per size), with each size embedded as genuine PNG-compressed image data decoded from your HEIC photo, not a renamed bitmap.

What happens with a multi-image HEIC file?

Each image inside a multi-image HEIC — a burst or Live Photo — becomes its own ICO package. A single-photo HEIC downloads one .ico file (with every selected size inside); a burst or Live Photo downloads a ZIP with one ICO per captured image.

Are my files uploaded?

No. Conversion runs locally in your browser and does not upload your file to Looty Tools servers.

What is validated before conversion?

The file must actually be a HEIC/HEIF container — the tool checks the ISO-BMFF ftyp brand, not just the filename or extension, before decoding.
