What Is PNG?
PNG is a raster image format that uses lossless compression, meaning it retains all original image data without quality loss. It supports transparency (alpha channel), making it a popular choice for graphics, icons, and images that need to be layered over other content.
- Web graphics with transparency
- Screenshots and interface elements
- Logos and icons
- Images requiring sharp detail
PNG files are typically larger than JPG files for photographic content because lossless compression is less efficient for complex, high-color images.
What Is ICO?
ICO is a file format used for icons in Microsoft Windows. It can contain multiple image sizes and color depths within a single file, allowing the operating system to select the appropriate version for different display contexts.
- Website favicons
- Windows application icons
- Desktop shortcuts
- Browser tab icons
ICO files typically contain versions at 16x16, 32x32, 48x48, and 256x256 pixels. When converting from another format, the image is resized to fit standard icon dimensions.
