How do I convert a TIFF file to ICNS?

Upload your TIFF file to our converter, choose the output size (or let the tool auto-select all Apple icon sizes), then click 'Convert'. The tool will resize your image to the required ICNS dimensions (16x16, 32x32, 128x128, 256x256, 512x512) and package them into a single .icns file. Download the result and apply it via Finder's Get Info or Xcode's AppIcon set.

Why should I convert TIFF to ICNS instead of keeping the original?

TIFF is a high-quality raster format designed for photography and print, but it is not natively supported by macOS for application icons. ICNS is Apple's container format that stores multiple PNG-compressed representations of an icon, allowing macOS to display the correct size anywhere from the Dock to the menu bar. Converting to ICNS also reduces file size significantly while preserving transparency and sharp edges.

How does TIFF to ICNS conversion handle layers, color profiles, and transparency?

The converter flattens any TIFF layers and converts the image to a 32-bit RGBA PNG for each required ICNS size. Color profiles (e.g., sRGB or Display P3) are embedded in the PNG metadata, and alpha channel transparency is fully preserved. Original DPI settings are ignored because ICNS sizes are pixel-based; the source is resized with bicubic interpolation for optimal sharpness. Non-square geometries will be padded to fit the square canvas.
