How to Convert PNG to ICO (Create a Favicon for Your Website)

Every website needs a favicon.ico. Converting a PNG logo to ICO format takes 3 seconds — no Photoshop or special tools needed. Upload to MegaConvert.io and select ICO — done in seconds, free.

The Problem

You designed your website's logo as a PNG. Now you need a favicon.ico file for the browser tab. ICO is a special format that contains multiple icon sizes in one file — you can't just rename a .png to .ico.

Why Convert?

• Browser tabs — favicon.ico is the classic format every browser recognizes.
• Multi-size — ICO contains 16x16, 32x32, and 48x48 in one file.
• Legacy support — older browsers require ICO format specifically.

How to Convert Online

1. Go to megaconvert.io/png-to-ico.
2. Drag and drop your .png file.
3. Download your .ico.

No account. No watermarks. Files auto-delete after 1 hour.
