How do I convert an ICNS file to JPEG using this tool?

Upload your ICNS file, choose JPEG as the output format, select the desired resolution if available, and click Convert. The converter flattens the icon to a raster and outputs a .jpg file. Download it from the result page.

Why should I convert ICNS to JPEG?

ICNS is Apple's icon format, limited to macOS/iOS. JPEG is a universal raster format that opens in any browser, viewer, or editor, making it ideal for websites, documents, and sharing. Conversion also reduces file size via JPEG compression, though transparency is lost.

What happens to transparency and multiple resolutions when converting ICNS to JPEG?

ICNS files often contain multiple icon sizes and an alpha channel for transparency. JPEG does not support transparency, so the alpha is discarded and filled with white (or black if you choose). The converter uses the highest-resolution version from the ICNS and scales it to your selected output size. Other metadata like color profiles are preserved if embedded.
