02 / what you get

What happens to your data

Kept

  • Every pixel and the transparency of the PNG are read exactly as they are
  • One .ico file with six sizes inside: 16, 32, 48, 64, 128 and 256 pixels, as Windows and browsers expect
  • Transparency is kept

Good to know

  • Icons are square. A picture that is not square is fitted inside the square with transparent padding, not cropped.
  • For a sharp result start from a square image of at least 256×256 pixels.

PNG vs ICO

PNG

A PNG file stores images without losing any quality (lossless), and supports transparency. It's the default choice for screenshots, logos, icons, and any graphic that needs a see-through background.

Used in: Screenshots · Logos & icons · Graphics with transparency

ICO

An ICO file bundles one or more small icon images into a single file, traditionally used for Windows application and file-type icons. It's still the required format for website favicons today.

Used in: Website favicons · Windows app icons · Desktop shortcuts
