How do I convert an ICNS file to DIB?

Upload your ICNS image and select the exact scale you need (e.g., 512×512). Choose 24-bit or 32-bit DIB with alpha bitfield, then click Convert. The tool reads the selected PNG data from the ICNS container and writes a Device-Independent Bitmap with the corresponding header and pixel array.

Why should I convert ICNS to DIB?

ICNS is a container used by macOS to store multiple icon scales in one file, while DIB is a Windows bitmap format often required by legacy or custom applications, game engines, and embedded systems. Converting lets you reuse Apple’s icon set on Windows without editing every resolution manually, and DIB’s uncompressed nature avoids decode overhead.

What happens to transparency and resolution when converting ICNS to DIB?

You can choose any resolution stored in the ICNS (16, 32, 64, 128, 256, 512, or 1024 px). If you select 32-bit DIB, the alpha channel is preserved as a bitmask (BI_BITFIELDS). The conversion does not upscale unless you explicitly set a custom size; otherwise, the pixel data is copied exactly from the decoded PNG/JPEG2000 tile, so no compression artifacts are introduced beyond the original.
