AVIF stands for the AV1 Image File Format. It uses the AV1 video codec inside a HEIF (High Efficiency Image File Format) container. AVIF was released in February 2019. This format compresses images better than JPEG and WebP, creating smaller files without losing quality.
AVIF supports high dynamic range (HDR), wide color gamut, transparency, and animation. These features make AVIF good for photos and websites.
How to Open an AVIF File:
- Windows: Use the AVIF Extension for Photos app, or open with IrfanView, GIMP, or XnView MP.
- macOS: Open with GIMP, ImageGlass, or convert files using Squoosh.
- Linux: Use GIMP, ImageMagick, or install custom AVIF plugins.
- Web: Most modern browsers support AVIF, including Chrome, Firefox, Edge, and Opera.

ICO file is a type of computer file used to store icons. Icons are small pictures representing programs, files, folders, or computer functions. ICO files contain multiple icon images in different sizes and with different color details. This allows the icon to display clearly and sharply in different contexts and sizes on your screen.
The ICO format was created by Microsoft. It was first used in Windows 1.0 in 1985. ICO files support transparency. This means that parts of the icon can be seen, so the icon can look good on a different backgrounds. ICO files typically include image sizes ranging from 16×16 pixels to 256×256 pixels, and sometimes larger.
How to Open an ICO File:
- Windows: You can open ICO files with programs like Microsoft Photos, Adobe Photoshop, or GIMP.
- macOS: macOS does not use ICO files for its system icons, but you can open them with GIMP or use online tools to convert them.
- Linux: You can open ICO files with GIMP or other image viewers that support the ICO format.
- Web: Web browsers usually show ICO files as website icons (favicons). To edit them, you might need image editing software or special viewers.
