PNG to ICO Converter Online — Create Favicons Free

Need a favicon for your website or a Windows icon? The MyPDF PNG to ICO converter transforms PNG images into multi-size ICO files — perfect for browser tabs, desktop shortcuts, and app icons.

How to Convert PNG to ICO

1. Upload your PNG image (ideally square, 256x256 px or larger).
2. Select the icon sizes to include (16x16, 32x32, 48x48, 256x256).
3. Download the ICO file with all selected sizes embedded.

ICO Size Guide

Size	Use Case
16x16	Browser tab favicon
32x32	Windows taskbar
48x48	Windows desktop icon
64x64	High-DPI taskbar
256x256	Windows Explorer large icons

Practical Tips

• Start with a 256x256 or 512x512 PNG — the converter will scale down for smaller sizes. Starting too small produces blurry icons.
• Use simple designs — favicons are tiny, so detailed images become unrecognizable at 16x16.
• Include multiple sizes in one ICO file for the best display across different contexts (browser, desktop, taskbar).

What is the difference between ICO and PNG favicon?

Modern browsers support PNG favicons via , but ICO is universally supported including older Internet Explorer. ICO can also embed multiple sizes in one file.

Can I include transparency in my ICO?

Yes. ICO fully supports transparency from your PNG's alpha channel. Transparent areas will show the background behind the icon.
