How do I convert X3F files to ICO using this tool?

Upload your X3F file(s), choose ICO as the output format, optionally select the desired icon size (e.g., 256x256, 64x64), then click Convert. Once processed, download your ICO file(s) directly from the results page.

Why should I convert X3F to ICO?

X3F is a RAW camera format with high dynamic range and fine color detail, but it's not widely supported by applications or operating systems for icon usage. ICO is the standard Windows icon format, allowing you to use your high-resolution images as favicons, application icons, or desktop shortcuts with proper transparency and scalable sizes.

How does the conversion handle X3F raw data when saving to ICO?

The converter decodes the X3F raw data, applying tone mapping and color space conversion to sRGB for realistic rendering. It then resizes the image to your chosen ICO dimensions (up to 256x256) and outputs a 32-bit ICO with 8 bits per channel and an alpha channel for transparency. While the ICO format cannot retain the full 12-14 bit dynamic range of the raw file, the conversion preserves visual appearance and transparency for practical icon use.
