ARW to ICO

Why convert ARW to ICO?

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

Develop RAW into a ready-to-use photo

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

Supports transparent backgrounds

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

Create a favicon or app icon

ICO is the icon format every browser and Windows understands. Convert a square ARW to get a favicon for your site or an icon for a desktop shortcut.

What is an ARW (camera RAW) file?

ARW is the camera RAW format of Sony - Alpha mirrorless and DSLR cameras and Cyber-shot compacts. 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 an ARW (camera RAW) file

Sony Imaging Edge opens ARW 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 ARW to JPG online.

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

What is an ICO file?

ICO is the icon format of Microsoft Windows and the classic format for website favicons - the little image in a browser tab. One ICO file can hold several sizes (16 × 16, 32 × 32, 48 × 48 and more), so the icon looks sharp everywhere.

ICO supports transparency, so icons can have rounded or irregular shapes. Modern sites often add PNG and SVG favicons too, but favicon.ico is still the universal fallback.

How to open an ICO file

Windows shows ICO files in File Explorer and opens them in Photos; Mac Preview opens them too. GIMP and online editors can edit them. To make one, convert a square PNG - or use the Favicon Generator for a complete set.

Extension: .ico
Sizes: Several in one file (16-256 px)
Transparency: Yes
Best for: Favicons, Windows icons
