You can't include two different app icons for one app, and the macOS 11 app icon style looks fine on a Mac running Catalina or earlier. Design a beautiful icon that clearly represents your app. Combine an engaging design with an artistic interpretation of your app's purpose that people can instantly understand.

| Type of format |
The Apple Icon Image format is the icon format used in Apple Inc.'s macOS. It supports icons of 16 × 16, 32 × 32, 48 × 48, 128 × 128, 256 × 256, 512 × 512 points at 1x and 2x scale, with both 1- and 8-bitalpha channels and multiple image states (example: open and closed folders). The fixed-size icons can be scaled by the operating system and displayed at any intermediate size.
File structure[edit]
The file format consists of an 8 byte header, followed by any number of icons. Google sheets for mac.
Header[edit]
| Offset | Size | Purpose |
|---|---|---|
| 0 | 4 | Magic literal, must be 'icns' (0x69, 0x63, 0x6e, 0x73) |
| 4 | 4 | Length of file, in bytes, msb first |
Icon data[edit]
| Offset | Size | Purpose |
|---|---|---|
| 0 | 4 | Icon type, see OSType below. |
| 4 | 4 | Length of data, in bytes (including type and length), msb first |
| 8 | Variable | Icon data |
Compression[edit]
| lead value | tail bytes | result uncompressed |
|---|---|---|
| 0…127 | 1…128 | 1…128 bytes |
| 128…255 | 1 byte | 3…130 copies |
Over time the format has been improved and there is support for compression of some parts of the pixel data. The 32-bit ('is32', 'il32', 'ih32','it32') and ARGB ('ic04', 'ic05') pixel data are often compressed (per channel) with a format similar to PackBits.[1]Some sources mentioned that the OS supports both compressed or uncompressed data chunks.
The following pseudocode decompresses the data:
Example: 02 01 02 02 80 03 81 04 82 05 should decompress to 01 02 02 03 03 03 04 04 04 04 05 05 05 05 05

Support[edit]
Various image viewers can load *.icns files, and free and open source converters from or to PNG also exist.[2][3]GTK+ can load *.icns resources since 2007.[4] Other tools supporting the format include the Apple Icon Composer and icns Browser, The Iconfactory, and IconBuilder.
MacOS[clarification needed] offers the built-in iconutil command line tool to pack and unpack *.icns files.

SVG (scalable vector graphics) support allows you to easily convert from SVG files. No more painstakingly exporting each individual icon from Illustrator or Inkscape.
Drag and Drop batch conversion is supported in both the Mac OS X version and the Windows version, for a fast and intuitive workflow, whether you're converting one icon or ten-thousand.
Advanced options make it easy to get the exact icons that you need. Most icon converters only support 32-bit icons - iConvert Icons can read and write 1, 4, and 8-bit icons.
Color calibration is built into iConvert Icons, so you can spend your time focused on designing instead of tinkering with color profiles.
Software developers can use iConvert Icons to quickly create app icons for both iOS and Android. It even gets the naming right so the icon resources can be added right into the project without any changes.
iConvert Icons can convert both ways, images to icons, and icons to images. This is especially useful for bloggers and software reviewers. Just drag an app onto iConvert Icons and save it to a PNG - ready to use in your website or blog!
