  3. 3Click 'Download ICO' and place the file in your website's root directory

Favicons — the small icons that appear in browser tabs, bookmarks, and browser history — must be in ICO format for maximum browser compatibility. Our PNG to ICO converter creates a proper multi-size .ico file from your PNG, entirely in your browser.

Our converter creates an ICO file containing both 32×32 and 16×16 pixel versions of your image, which are the two sizes most browsers use. Your PNG is resized proportionally to fit these dimensions using the browser's built-in image scaling.

No upload required. The ICO file is generated using a pure JavaScript ICO encoder running in your browser. Your original PNG and the resulting ICO file never leave your device.

For best results: use a square PNG with a simple, recognizable design. Favicons are tiny — detailed images become unrecognizable at 16×16 pixels. Simple logos, letters, or bold symbols work best.

Frequently Asked Questions

Where do I put the .ico file after downloading?
Place favicon.ico in the root directory of your website (e.g., https://yourdomain.com/favicon.ico). Most browsers check this location automatically. You can also reference it explicitly with: <link rel='icon' href='/favicon.ico'>
What size should my PNG be before converting?
For best quality, start with a square PNG at 512×512 or 256×256 pixels. Our converter scales it down to 32×32 and 16×16. Starting larger ensures the downscaled versions are sharp.
Does the ICO file contain both 16×16 and 32×32 versions?
Yes. Our converter packages both sizes into a single .ico file. The browser automatically picks the most appropriate size based on where the favicon is displayed.
Is it really free? Are there any limits?
Yes, completely free with no limits. You can convert as many files as you want, as large as your device's memory allows. We don't have a server to run, so we have no reason to charge or impose limits.
Do you upload my files to your server?
No. All conversions happen locally in your browser using the browser's built-in image APIs. Your files never leave your device. We do not have servers that process files — by design, not by promise.
What is the maximum file size?
There is no hard limit set by us. The only constraint is your device's available memory. Most modern devices handle files up to several hundred megabytes without any issues.
Do I need to create an account?
No account required. We don't have a user system. Open the page, drop your file, download the result — that's it.
