What is ICO?

ICO is Microsoft's icon file format, used since Windows 1.0 in 1985. An ICO file is a multi-resolution container — it can hold multiple images at different sizes (16x16, 32x32, 48x48, 64x64, 128x128, 256x256) within a single file. The operating system or browser automatically picks the most appropriate size.

ICO files are used for desktop application icons, file type icons, and website favicons. A typical favicon.ico contains 4–6 size variants. Internally, ICO images can be stored as either BMP or PNG data.

What is PNG?

PNG (Portable Network Graphics) is a lossless image format that supports transparency via alpha channels. Converting ICO to PNG extracts a single image at the largest available size, giving you a clean, editable image file.

PNG is widely supported across all devices, browsers, and image editors. It preserves exact pixel data without compression artifacts, making it ideal for icons, logos, and graphics.

Why Convert ICO to PNG?

Extract icon images

ICO files bundle multiple sizes in one container. Converting to PNG extracts the largest image as a standard, editable file you can use in any application.

Edit & modify

Most image editors cannot edit ICO files directly. Converting to PNG lets you open, modify, and resave icons in Photoshop, GIMP, Figma, or any editor.

Web use

Modern browsers support PNG favicons via the <link rel="icon"> tag. Converting ICO to PNG enables use in modern web favicon implementations.

Documentation & design

When documenting UI designs or creating brand assets, PNG icons are more versatile than ICO for presentations, documents, and design tools.
