CR2 to ICNS

Why convert CR2 to ICNS?

The main difference: CR2 is an unprocessed sensor data format, while ICNS is a lossless format. ICNS can have a transparent background, CR2 can't.

Develop RAW into a ready-to-use photo

A CR2 file holds the raw readings from the camera sensor, not a finished picture. Converting it to ICNS applies the camera's colors and gives you a normal photo you can share, print or post right away.

Supports transparent backgrounds

ICNS can hold a transparent background. Convert your image first, then cut out the background or place it on top of other designs.

What is a CR2 (camera RAW) file?

CR2 is the camera RAW format of Canon - EOS DSLRs released between 2004 and 2018. Instead of a finished photo, a RAW file stores the unprocessed data straight from the camera's sensor.

That gives photographers maximum room to adjust exposure, white balance and color afterwards, but RAW files are large (often 20-60 MB) and need special software to view. Converting to JPG produces a normal photo you can share right away.

How to open a CR2 (camera RAW) file

Canon Digital Photo Professional opens CR2 files, and Adobe Lightroom, Photoshop (Camera Raw), Capture One, darktable and RawTherapee support them too. Mac Photos and Preview open most RAW formats; on Windows, the free Raw Image Extension adds support to the Photos app. Without any of these, convert CR2 to JPG online.

Extension: .cr2
Made by: Canon cameras
Contains: Unprocessed sensor data
Best for: Editing straight-from-camera photos

What is an ICNS file?

ICNS is Apple's icon format for macOS apps. Like ICO on Windows, one file bundles the same icon in several sizes - from 16 × 16 up to 1024 × 1024 pixels - so it looks crisp in the Dock, Finder and on Retina displays.

Developers need ICNS when packaging a Mac application. For websites and Windows, use ICO or PNG instead.

How to open an ICNS file

Mac Preview opens ICNS files and shows every size inside. Xcode and icon tools create them. Windows can't open ICNS without extra software - convert it to PNG to view it there.

Extension: .icns
Sizes: 16 to 1024 px in one file
Transparency: Yes
Best for: macOS app icons
