Why would I need ICO instead of HEIC?

ICO is the format Windows expects for application icons, desktop shortcuts, and favicons.

What happens with a multi-image HEIC file?

Every decoded image is kept. A single-image HEIC downloads as one file; a multi-image HEIC (a burst or Live Photo) downloads as a ZIP containing every decoded image, never just the first one.

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.

How to Convert HEIC to ICO in Your Browser

Converting a HEIC or HEIF photo to ICO produces a real Windows ICO icon — a single size, or the default multi-size package covering 16 through 256 px. This guide covers the steps and what to know about transparency and file size.

Step-by-step conversion

Open /tools/heic-to-ico.
Choose a HEIC or HEIF file — the content is validated before conversion, not just the filename or extension.
Select Convert & download.
Save the .ico file from your browser downloads.

Transparency and file size

Each embedded icon size keeps the source’s alpha channel — this is a genuine ICO container (ICONDIR plus one entry per size), with each size embedded as real PNG-compressed image data.

Source-specific behavior

HEIC/HEIF containers can hold more than one image (a burst or a Live Photo). A single-image file downloads as one output file; a multi-image file downloads as a ZIP with every decoded image converted, so nothing is silently dropped.

Privacy

Conversion runs locally in your browser. The file is not uploaded to Looty Tools servers for this workflow.
