Convert RAW to ICO
About RAW
A RAW image file is often called a 'digital negative'. It contains the unprocessed, untouched data directly from a digital camera's sensor. Unlike formats like JPEG, which are processed and compressed by the camera, a RAW file gives the photographer complete control over editing aspects like white balance, exposure, and color. This provides the highest possible quality and editing flexibility.
About ICO
The ICO (Icon) file format is used for computer icons in Microsoft Windows. An ICO file contains one or more small images at multiple sizes and color depths, allowing them to be scaled appropriately. The most common use for ICO files on the web is for 'favicons', the small icon displayed in a browser's tab.

Frequently Asked Questions
Can I open a RAW file in any program?
No, RAW files require special software. Each camera manufacturer has its own proprietary RAW format (e.g., .CR2 for Canon, .NEF for Nikon), so you need a program like Adobe Lightroom, Photoshop, or manufacturer-specific software that can read your camera's specific file type.
Why not just shoot in JPEG?
Shooting in JPEG is faster and produces ready-to-use files. However, shooting in RAW provides a much higher quality source file with more latitude for making corrections and creative adjustments during post-processing. For professional work or serious hobbyists, RAW is the preferred format.
Can I use a PNG for a favicon instead of an ICO?
Yes, modern browsers have excellent support for using PNG files as favicons. You can simply link to a .png file in your HTML header. However, the .ico format can still be useful as it can contain multiple icon sizes in a single file, which some browsers and platforms use in different contexts (like bookmarks or desktop shortcuts).
What's the maximum size for an ICO file?
While historically icons were very small (16x16 or 32x32 pixels), the ICO format can technically support icons up to 256x256 pixels. This allows for high-resolution icons on modern displays.
