Q: What are the limitations of converting images to vector formats?

What is ICNS (Apple Icon Image)?
ICNS (Apple Icon Image) is a file format used by macOS for storing application and document icons, supporting multiple image sizes and resolutions within a single file.
This format allows applications to provide appropriate icon versions for different display contexts, from small menu icons to large high-resolution versions for Retina displays.
ICNS files can contain multiple image representations ranging from 16×16 pixels to 1024×1024 pixels, each optimized for different usage scenarios within the macOS interface.
Modern ICNS files support transparency through alpha channels and can contain both standard and high DPI (Retina) versions of each icon size to ensure sharp display regardless of screen resolution.
How to open ICNS?
ICNS files can be opened natively on macOS using Preview or QuickLook, which can display the various icon sizes contained within the file.
Professional icon design software like IconJar, Axialis IconWorkshop, and Icon Slate can edit ICNS files and the multiple image sizes they contain.
For Windows and Linux users, graphics applications like GIMP and XnView (with plugins) can import ICNS files for viewing and basic editing.
Online icon converters and editors often support the ICNS format, allowing viewing and conversion without specialized desktop software.
ICNS is Developed by: Apple Inc.
ICNS was Released on: Mac OS 8.5 (1998)

How to convert ICNS?
To convert ICNS files to standard image formats like PNG or JPEG, use our online converter that can extract individual icon sizes or the highest resolution version available.
For creating ICNS files from standard images, tools like IconKit, Icon Composer (legacy), and many modern icon design applications can compile multiple image sizes into the ICNS format.
When converting between ICNS and other icon formats (like ICO for Windows), specialized icon conversion utilities ensure that all size variants and transparency information are properly preserved.
For developers, command-line tools like iconutil (built into macOS) can convert between ICNS and a folder of PNG files (iconset), facilitating integration with automated build processes.
