Convert HEIC to ICO
HEIC is Apple's high efficiency photo format used by iPhones and iPads. Many apps cannot open it directly. ICO is the container Windows and browsers require for favicons and application icons, so this conversion is about producing that specific file type rather than about quality or size. The conversion runs entirely in your browser: there is no upload, no file size limit and no watermark on the result.
Drop your HEIC files below and download ICO in seconds. Free, unlimited and completely private: the conversion runs inside your browser, so your files never leave your device and are never uploaded to a server.
No upload. Works with your network switched off. Check it yourself, or read what actually happens to your file.
Why convert HEIC to ICO?
Apple made HEIC the default camera format on iPhone because it stores photos at roughly half the size of JPG. Outside the Apple ecosystem support is poor: Windows needs paid extensions and many websites reject HEIC uploads, making it one of the most converted formats on the web.
ICO files bundle one or more icon sizes into a single file that Windows and browsers use for favicons and app icons. Regular image viewers often refuse to open them, and most editors cannot save them, so a converter is the practical way in or out of the format.

What changes when you convert HEIC to ICO
| What happens | |
|---|---|
| Image quality | Depends on the quality setting above, which controls how much detail ICO keeps. |
| Transparency | HEIC has no alpha channel, so there is no transparency to lose. |
| EXIF and GPS | Removed. The conversion goes through a pixel buffer, so camera data and location are not carried into the ICO file. |
| Colour profile | Not carried across. The image is handled in sRGB, which is right for the web and wrong for colour-managed print work. |
| Animation | Not applicable. HEIC files here are single images. |
| File size | Varies with the content of the image. No figure is quoted here, because none has been measured on a documented test set. |
