4 Solutions | How to Convert PNG to ICO on Windows and Mac FREE

In an already digitized and ubiquitous world, image formats like ICO and PNG are all over our lives, but you barely notice them. Image formats like PNG are often used to display image details on websites because of their transparency and lossless compression. And ICO images are generally used as different icons of software or applications. Of course, those icons are replaceable. Although there are lots of free ICO images you can download from the Internet, you may prefer using your own pictures to create unique icon images. Therefore, in this post, here are four free solutions for you to solve the problem of converting PNG to ICO on Windows and Mac. I hope you get the help you need.

Something About ICO and PNG

📌 What is ICO?

ICO (Icons)is a file format that contains icon images. This format is usually used on applications, files, and folders of Microsoft Windows. But it doesn’t mean it won’t fit on Mac. There are icons on macOS systems with .icns extensions. Any clickable software and the cover of the document you see are in ICO format. And ICO is not just a single image. In fact, it is a combination of multiple images with the transparency feature.

📌 What is PNG?

PNG (Portable Graphics Format) is a raster image format. Like the JPG format, it’s basically compatible with all browsers, operating systems, and devices because it has been developed for a long time. But unlike the JPG format, it uses lossless compression, thus preserving high-quality images. Another point is that this image format supports transparent backgrounds, making it more suitable for displaying on various websites. But the disadvantage is that due to its lossless compression, this format of the picture will usually be larger, making it a terrible choice for applications icons.

The Comparison between PNG and ICO

In fact, the two image formats are different in nature. Because the PNG image format is more suitable for website images, it has both transparency and lossless compression features. The ICO format itself exists only in the use of icons. So they’re basically tiny in size and need to be higher in quality. But the user has permission to change the style of the icon, so why not customize an icon you like?
Here is a comparison list of PNG and ICO image formats. From it, you will know the fundamental difference between the both of them.

File Extension .png .ico
Image quality Lossless Image Suitable for icons ⭐⭐
File Size Large Small ⭐⭐⭐
Compression Lossless ⭐⭐ Already compressed ⭐⭐
Compatible The vast majority of devices and apps ⭐⭐⭐ Available on Windows and Mac ⭐⭐⭐

Why Convert PNG to ICO

In fact, unlike other image conversions, the reason to convert PNG to ICO is straightforward. Just because PNG is more high-definition and lossless, and because of the transparency of the supported ICO files, PNG is more suitable than other image formats for converting to ICO.

Use MS Paint to Convert PNG to ICO Images

Windows system has a built-in image editing tool to do some basic editing and image conversion. Well, technically, it doesn’t convert image format. It only has the feature to save an image in a different format. So, it doesn’t come with a part for users to make batch conversions. However, it is a free tool that doesn’t need to download. And, of course, creating PNG images become ICO format is feasible. It is well enough for users who only want to try a couple of image conversions.

ms paint save png to ico

Step 1. Open your PNG image with MS Paint.

Step 2. File > Save as and select Other formats;

Step 3. Then, you can click Save to get the ICO file.

I will choose to use this if I only have one or two PNG images to convert. This is absolutely the easiest method to make the conversion. You don’t have to download anything or purchase anything. It is slower than other methods.

How to Convert PNG to ICO on Mac

Unfortunately, WorkinTool Image Converter is currently unavailable on the Mac system. Also, even though it has a Preview app that is similar to MS Paint to view and edit images, it isn’t equipped with the conversion feature nor the ICO format for users to save. So, you only have one way left: to use a third-party application tool. For example, Adobe Photoshop can help. 

Well, I am sure you must know Adobe Photoshop. As the early pioneer in image editing, it changed the whole image market. This tool indeed has the absolute feature of turning images into ICO as well. But compared with other professional image converters, the method in Photoshop can be complex. And the price for this software is also famously high. Thankfully, for new beginners, it will give you a 7-day trial plan to try it out. And that is how we are going to use it to convert PNG to ICO files.

📕 how to transform PNG into ICO via Adobe Photoshop

1. Open the PNG file with Adobe Photoshop.

2. Select the Image option on the header bar and choose Convert to ICO.

3. Customize the resolution and color of the image and the file format. Then it will start to convert this PNG image to an ICO file immediately.


Even though Photoshop is very famous for image editing, it may mean something other than that it is good in every feature. For image conversion, it can do better. Yes, it requires too much. For people like you and me, we only want our image to become a functional ICO file. And this tool will need to alter every parameter to “generator” an ICO file. What if I have a pile of PNG images waiting for me to convert? It will take me forever to do it. Besides that, if you only want to convert images without editing them in detail. We sincerely don’t recommend you use it after the free trial expires. It’s not worth paying a lot of money to convert a format.

Alternative: Online PNG to ICO Converter

You can try online image conversion tools if you want to avoid downloading them or paying extra money for those desktop image converters. They are equally brilliant and better in image conversion output. But you should know that all online converters require you to upload your PNG images to the Internet. So, please only use any one of them if your images are not involved with business privacy or other legal issues. Then from the effect to see, we recommend users try Convertio PNG to ICO.

Convertio is a professional online file format conversion tool. It consistently ranks in the top three on Google’s conversion list. This tool covers all files, including images, for free conversion. You don’t need to download anything or register an account too. The only thing you need to do is to put the PNG image and select ICO for output. It is well-prepared to work.

2: Add your PNG picture(s) and select ICO to export.
