Why PNG to ICO?
ICO (Icon) format is the standard for website favicons—the small icon that appears in browser tabs, bookmarks, and the address bar. Converting PNG to ICO creates a proper favicon file that works across all browsers.
Modern ICO files can contain multiple sizes (16x16, 32x32, 48x48) in a single file, letting browsers pick the best size for their needs. We automatically generate these sizes from your PNG.
For best results, start with a square PNG at least 256x256 pixels. Simple, recognizable designs work best at tiny sizes—detailed images become unrecognizable at 16x16.

Frequently Asked Questions
Start with a square PNG at least 256x256 pixels. We'll generate smaller sizes automatically. Larger source images produce better quality favicons.
While modern browsers support PNG favicons, ICO is still the most universally compatible format. ICO also supports multiple sizes in one file, letting browsers choose the best size.
Place it in your website's root directory. Most browsers automatically look for /favicon.ico. You can also add a <link rel="icon"> tag in your HTML.
ICO doesn't work for iOS home screen icons. You'll need separate PNG files (apple-touch-icon.png) at 180x180 for that. Our PNG output works for Apple devices.
