About this conversion
ICO is the standard format for browser favicons and Windows application icons. When you upload a favicon.ico to your website root, browsers automatically detect and display it in the tab bar, bookmarks, and address bar. Converting your PNG logo or icon to ICO ensures maximum compatibility across all browsers and operating systems. For best results, start with a square PNG at least 256×256 pixels.
Frequently Asked Questions
What size should my PNG be before converting to ICO?
Use a square PNG of at least 256×256 pixels. ICO files can contain multiple sizes — the converter will generate the appropriate favicon size for browser compatibility.
Where do I put the favicon.ico file on my website?
Place it in your website's root directory (e.g., /public/favicon.ico in Next.js). Most browsers automatically look for favicon.ico at the root.
Should I use ICO or PNG for my favicon?
ICO for maximum compatibility, especially for older browsers and Windows desktop shortcuts. Modern browsers also support PNG favicons, but ICO is the safe universal standard.
Is my image processed locally?
Yes. Your PNG is converted to ICO entirely in your browser. Nothing is uploaded to any server.
