You just finished designing a logo for your website or app. It looks clean. You exported it as a PNG. Now you need to set it as your website’s favicon, that tiny little icon that shows up in browser tabs.

You open your HTML, add <link rel="icon" href="logo.png">, deploy, and… it kind of works. Sometimes. Chrome shows it, Firefox ignores it, and Internet Explorer (yes, people still use it) displays nothing.

The reason? Favicons were originally designed around the ICO format, not PNG. An ICO file can bundle multiple icon sizes (16x16, 32x32, 48x48) into one neat package, which is exactly what browsers and operating systems expect.

If you want a favicon that works flawlessly everywhere, you need a proper .ico file.

The favicon conversion problem

This should be straightforward, but it is surprisingly awkward:

Your image editor probably cannot save ICO files. Photoshop, Figma, and Canva all export PNG, JPG, SVG, but not ICO. You need a separate tool.
Online “favicon generators” are overcomplicated. Most of them want you to create an account, offer 15 different sizes you do not need, and then email you a zip file. All you wanted was one .ico file.
Quality loss is common. Some converters aggressively compress the icon, turning your crisp logo into a blurry pixelated mess in the browser tab.

Convert PNG to ICO instantly in your browser

The GetAnyFile Image Converter handles ICO conversion natively. Since it runs entirely in your browser via WebAssembly, the conversion is instantaneous, no uploads, no waiting, no accounts.

Why this works better than online generators:

Drop in, get out. There is no multi-step wizard. You drop your PNG in, pick ICO as the output, and download. Three clicks.
Crisp quality. The converter preserves the full clarity of your original PNG at proper icon dimensions.
Works with any image format. Starting with a JPG, WebP, or even a HEIC file? Convert any of those straight to ICO in one step.
No account needed. We do not need your email to give you an icon file.

How to create your favicon

Open the PNG to ICO Converter.
Drag your logo image onto the page. (Pro tip: start with a square image. Non-square images will be stretched to fit, and that rarely looks good.)
Set the output format to ICO.
Click Convert.
Download your .ico file.

Using your new favicon

Once you have your ICO file, adding it to your website takes one line of HTML in your <head> tag:

<link rel="icon" type="image/x-icon" href="/favicon.ico">

Place the favicon.ico file in the root directory of your website (the same folder as your index.html), and every browser, old and new, will pick it up automatically.

Quick tips for better favicons:

Start with at least 64x64 pixels. Favicons display at 16x16 in browser tabs, but higher resolution source images give the converter more detail to work with.
Keep it simple. Your logo might look great at full size, but at 16 pixels wide, only bold shapes and strong colors survive. If your logo has fine text or thin lines, consider using a simplified version for the favicon.
Use a transparent background. Export your PNG with transparency before converting to ICO. This way the favicon blends naturally with the browser’s tab bar regardless of whether the user is in light mode or dark mode.

Beyond favicons

ICO files are not just for websites. Windows uses them for:

Desktop shortcuts, Custom icons for application shortcuts
File type associations, Programs that register custom file types need ICO icons
Taskbar pins, The icon shown when a program is pinned to the Windows taskbar

If you are building a Windows application or need custom desktop icons, the same PNG-to-ICO converter handles those use cases just as easily.
