What is PNG?
PNG (Portable Network Graphics) is a lossless image format widely used for graphics, logos, and images with transparency. PNG is the ideal source for favicon creation because it supports full alpha channel transparency, ensuring your favicon looks clean on any browser theme.
For best favicon results, start with a square PNG image at least 512x512 pixels. The converter will generate all the sizes needed for the ICO container.
What is ICO?
ICO is the Windows icon format and the standard for website favicons. A single ICO file can contain multiple images at different sizes (16x16, 32x32, 48x48, 256x256), allowing browsers and operating systems to display the most appropriate size.
Every website needs a favicon.ico file. It appears in browser tabs, bookmarks, history, desktop shortcuts, and mobile home screen icons. A missing favicon signals an unprofessional website.
