PNG to ICO
Upload your image
Drop in a PNG, JPG or WEBP. A square image with a transparent background makes the cleanest icon, but any picture works, non-square images are fit inside the icon with transparent padding.
Choose the icon sizes
Tick the resolutions to bundle into the .ico. 16, 32 and 48 px cover browser tabs and bookmarks; add larger sizes like 256 px for high-DPI desktops. Every checked size goes into one file.
Download your .ico
Everything runs in your browser, the image is never uploaded. Save the .ico and place it in your site root as favicon.ico, or reference it from your HTML.

What Is a PNG to ICO Converter?
A PNG to ICO Converter turns a PNG, JPG or WebP image into an .ico file that can be used as a website favicon or application icon. The ICO format can contain several resolutions in a single file, allowing browsers and operating systems to select a suitable size for different interfaces.
Favicons help users identify websites in browser tabs, bookmarks and other interface areas. They may also appear next to a website in Google Search results when the favicon and its implementation meet Google’s requirements.
How to Convert an Image to ICO
Upload a PNG, JPG or WebP image to the tool. A square source image with a transparent background usually creates the cleanest icon. Non-square images can still be converted because the tool fits them within the icon area and adds transparent padding where necessary.
Select the resolutions that should be included in the ICO file. Sizes such as 16, 32 and 48 pixels are commonly used for browser tabs and bookmarks, while larger versions such as 256 pixels can provide clearer results on high-resolution desktop interfaces. Every selected size is bundled into one .ico file.
After processing, download the generated file and save it as favicon.ico in the website root or reference its location through a <link rel="icon"> element in the HTML document. Browsers can use the available icon information to select an appropriate resource.
Why Use a Multi-Size ICO File?
A small icon may look sharp in a browser tab but become blurred when enlarged for another interface. Including several resolutions allows the same ICO file to provide a more suitable image for each display size instead of forcing one version to be scaled repeatedly.
For Google Search, the favicon must use a square aspect ratio and be at least 8 × 8 pixels. Google recommends an image larger than 48 × 48 pixels so it remains clear across different surfaces, although meeting the guidelines does not guarantee that the favicon will be displayed.
Private Conversion in Your Browser
The conversion runs locally in the browser, so the selected image is not uploaded to a remote server. This makes it possible to create an ICO file from unpublished logos, client assets or internal application icons while keeping the original image on the device.
