Why use a PNG to ICO converter
A PNG to ICO converter lets you create a Windows icon or website favicon from a PNG image instantly. PNG is the ideal source format for ICO conversion because PNG supports full transparency — logos and icons with transparent backgrounds convert to ICO perfectly, preserving the transparent areas so the icon blends cleanly with any background color in Windows or in a browser tab.
ICO is the standard format for website favicons and Windows application icons. While modern browsers now also accept PNG favicons directly, ICO remains the most universally supported favicon format and is still required by many web servers, content management systems, and Windows applications.
When you need a PNG to ICO converter
Creating a website favicon — The favicon is the small icon that appears in browser tabs, bookmarks, and browser history next to your website name. Converting your PNG logo to ICO using this PNG to ICO converter produces a favicon.ico file that works with every web server and browser without exception.
WordPress favicon — WordPress websites need a Site Icon, which can be uploaded as PNG or ICO. Many WordPress themes and plugins specifically look for a favicon.ico file in the root directory. A PNG to ICO converter lets you create this file from your existing PNG logo.
Windows application icons — Windows applications, installers, and executable files use ICO format for their icons. Developers use a PNG to ICO converter to turn their app’s PNG logo into the required ICO format for their Windows builds.
Desktop shortcut icons — Windows lets you customise icons for desktop shortcuts and folders using ICO files. A PNG to ICO converter lets you create custom icons from any PNG image for personalised Windows shortcuts.
Browser extension icons — Chrome, Firefox, and Edge extensions require icons in PNG or ICO format. A PNG to ICO converter helps create the required icon files for browser extension development.
PNG vs JPG for ICO conversion
PNG is the better source format for ICO conversion compared to JPG for one key reason — transparency. PNG files support full alpha channel transparency, which means logos and icons with transparent backgrounds convert to ICO perfectly, with the transparent areas preserved. JPG files always have a solid white or colored background, which means converted JPG-to-ICO files will have a white rectangle around the icon instead of a transparent background.
If your logo is available as both PNG and JPG, always use the PNG version when creating an ICO file using this PNG to ICO converter.
How to use this PNG to ICO converter — step by step
Upload your PNG image by clicking the upload button above. For the best favicon result, use a square PNG image with your logo centred — ICO files are always square, so the tool crops or scales your image to fit the selected size. Select your preferred ICO size from the dropdown — 32×32 for standard favicons or 16×16 for very small browser tab icons.
Click Convert PNG to ICO. Your browser resizes the PNG to the selected size and creates an ICO file preserving any transparency. Download your ICO file and upload it to your website root directory or use it as a Windows icon.
Frequently asked questions about PNG to ICO conversion
Will the ICO preserve transparency from my PNG?
Yes. This PNG to ICO converter preserves transparency from your original PNG image in the output ICO file, so logos with transparent backgrounds will look correct on any background color.
What size should I use for a website favicon?
32×32 pixels is the most widely compatible favicon size and works in all browsers. For the smallest browser tab icon, 16×16 is used. Many developers create both sizes — start with 32×32 for the best balance of quality and compatibility.

How do I use the ICO file as my website favicon?
Upload the favicon.ico file to the root directory of your website — the same folder that contains your index.html or WordPress wp-config.php file. Most browsers will automatically detect and use it. You can also add it explicitly in your HTML head section.
