Convert PNG images to ICO favicon format online

PNG to ICO converts your PNG graphic into a proper multi-resolution favicon.ico file that browsers and operating systems expect. PNG is the ideal source format for favicon creation because it supports full alpha transparency and lossless compression — meaning your icon's crisp edges and transparent background carry over perfectly into every embedded ICO frame.

A single ICO file contains 16×16, 32×32, and 48×48 px variants, so your site icon always looks sharp — whether it appears in a browser tab, the address bar, bookmarks, or a Windows desktop shortcut. Non-square images are automatically center-cropped to square before scaling, so you get predictable results regardless of input dimensions.

No design software needed. Upload any PNG, click Convert, and get a standards-compliant favicon.ico ready to drop into your website's root directory. Simply place it alongside your index.html and browsers will detect it automatically. Your file is deleted from our servers immediately after you download it — fully free, no account required.

Tips for PNG to ICO Conversion

  • Start with a square PNG — non-square images are center-cropped to a square before conversion.
  • Use a 256×256 or 512×512 px source for the sharpest 16 and 32 px favicon frames.
  • Keep transparency in your PNG to get a clean favicon on any browser background color.
  • Test your favicon at 16×16 px before publishing — details that look fine at full size can become muddy at tab size.

PNG to ICO FAQ

What is an ICO file?
An ICO file is a special image container used for website favicons and desktop icons. Unlike a regular image file, it can store multiple resolutions inside one file so the operating system or browser can pick the most appropriate size automatically.
Which sizes are included in the converted ICO?
The converter embeds three sizes: 16×16 px (browser tab), 32×32 px (taskbar and bookmark icons), and 48×48 px (Windows desktop shortcut). This covers all common favicon usage scenarios.
Is transparency kept when converting PNG to ICO?
Yes. If your PNG has a transparent background, the alpha channel is preserved in every embedded frame. Your favicon will show the correct transparent areas on any browser background.
What PNG size should I start with?
For best results, upload a square PNG at least 48×48 px. A 256×256 or 512×512 px source image gives the downscaling algorithm the most detail to work with and produces the sharpest favicon frames.
How do I add the favicon.ico to my website?
Place the favicon.ico file in your website's root directory (the same folder as index.html). Modern browsers will find it automatically. You can also declare it explicitly with in your HTML .
Is my uploaded PNG kept private?
Yes. All processing happens on the server and your PNG file is deleted immediately after you download the ICO. We do not store, inspect, or share your images.
