Why Convert CR2 to ICO?

ICO files are the standard favicon format for websites. Converting a CR2 photo to ICO lets you create a custom favicon from a professional camera shot.

How to Convert CR2 to ICO

1

Upload your CR2 file. The RAW data is decoded at full resolution.

2

KoalaPic scales the image down to standard favicon sizes (16×16 through 256×256).

3

Download the multi-size ICO file, ready to use as a website favicon.

💡

Quality Note

The ICO file contains multiple sizes embedded in one file. For best results, crop your image to a square aspect ratio before converting.

Frequently Asked Questions

A single multi-resolution ICO containing 16×16, 32×32, 48×48 and 256×256 pixel versions. Windows selects whichever fits the context, so the icon stays sharp from a taskbar entry to a large desktop tile.

Only with a decisive crop. At 16×16 pixels there is room for roughly one recognisable shape, so a tight portrait or single high-contrast object reads while a landscape becomes mud. Crop before converting.

The format does — ICO stores 32-bit colour including an alpha channel. A CR2 provides no transparency of its own, so the icon is opaque unless you remove the background before converting.

No. ICO entries are square, so a 3:2 Canon frame is fitted to a square canvas. Crop to 1:1 first if you want to choose what stays in frame rather than leaving it to the conversion.
