What is a CR3 file?
CR3 – Canon RAW photo. CR3 is a RAW photo format from Canon: the data straight from the camera's sensor, before it is turned into a JPG. It keeps more detail to adjust, but needs a RAW converter to be opened.
CR3 Converter →What is an ICO file?
ICO – Windows icon. ICO is the Windows icon format. One file holds the same picture in several sizes, each at most 256 × 256 pixels; browsers also use it for the small icon on a tab (the favicon).

Good to know
- Icons are small: the picture is shrunk to fit 32 × 32 pixels unless you choose another size in Options (up to 256 × 256).
- CR3 files are developed on our server with the camera's own white balance, then saved as ICO. Expect a good-looking picture, not a replacement for your RAW editor.
- Tick Remove metadata in Options to leave out information stored in the picture, such as the camera and the place.
Frequently asked questions
Is converting CR3 to ICO free?
Yes. Everyone gets 25 free credits a day, with no account needed. Conversions on our server use one credit per started minute of work, so most cost a single credit. Credits reset at midnight UTC.

Up to 1 GB per file. This conversion runs on our server, which accepts files up to that size.
Can I change the size or quality of the ICO?
