Create Windows Favicons From Your PNG Logos
Every website needs a favicon — that tiny icon in the browser tab. Upload your logo as a PNG and we'll generate a multi-resolution ICO file containing 16x16, 32x32, and 48x48 sizes, ready to drop into your site's root directory.

How to Convert PNG to ICO
Upload your logo as PNG
Choose a square PNG logo — ideally at least 256x256 pixels. Transparency is preserved in the ICO output.
Select included icon sizes
We generate 16x16, 32x32, and 48x48 by default. Optionally add 64x64, 128x128, and 256x256 for high-DPI displays and Windows desktop icons.
Download the ICO file
Place the .ico file in your website's root folder as favicon.ico, or reference it in your HTML head. The browser picks the best size automatically.
Frequently Asked Questions
What sizes should I include in my favicon ICO?
expand_more
16x16 and 32x32 are essential — they cover browser tabs and bookmarks. Adding 48x48 improves Windows taskbar display. 256x256 is needed for Windows desktop shortcuts.
Does my source image need to be square?
expand_more
Yes. ICO files require square dimensions. If your logo isn't square, we'll center it on a transparent canvas and pad the edges.
Can I use a transparent background in my favicon?
expand_more
Absolutely. PNG transparency carries over into the ICO file. In browser tabs, the transparent areas show the tab's background color.
Do I still need a separate PNG favicon for modern browsers?
expand_more
Modern browsers support both ICO and PNG favicons. For maximum compatibility, use the ICO as a fallback and add a <link> to a 32x32 PNG for modern browsers.
How do I add the favicon to my website?
expand_more
Place favicon.ico in your root directory. Most browsers find it automatically. Optionally add <link rel="icon" href="/favicon.ico"> in your HTML <head>.
Pro Tips for PNG to ICO Conversion
Start with a 512x512 or 1024x1024 PNG for the best downscaling results — avoid upscaling small images
Test your favicon against both light and dark browser themes to ensure it's visible on both backgrounds
Keep your logo simple for small sizes — fine details disappear at 16x16 pixels, so bold shapes work best
