Check our videoThe ICO (Icon File) format is a widely used image file format primarily designed for storing computer icons in Microsoft Windows operating systems. It is supported by various graphic editing tools like Adobe Photoshop, GIMP, and online converters, as well as being natively compatible with Windows for displaying application and system icons. The format can store multiple images of varying sizes and color depths (up to 32-bit RGBA) within a single file, allowing for high-quality, scalable icons with transparency and anti-aliasing support.
JPEG 2000 Core Image File (JP2) is a highly efficient image format designed for high-quality still image compression, offering superior performance compared to traditional JPEG. It is widely supported by applications like Adobe Photoshop, GIMP, and IrfanView, as well as specialized tools such as Kakadu and OpenJPEG for encoding and decoding. The format uses wavelet-based compression, supports lossless and lossy compression, and includes advanced features like progressive decoding, region-of-interest coding, and metadata embedding for enhanced flexibility and scalability.
You can also convert ICO into many other file formats. Please see the complete list below.
