So, you have a PNG image—maybe a logo or a small icon—and you need it as an ICO file. ICO files are the ones Windows uses for program icons and website favicons. Let's walk through how to change your PNG into an ICO.
Why Convert PNG to ICO?
PNG is a great format for pictures on the web because it supports transparency. But if you want to set an icon for a software application on Windows or create a favicon for your website, you'll need an ICO file. The ICO format can store multiple sizes of the same image in one file, which is exactly what Windows needs to show your icon clearly on the desktop, in the start menu, and in the taskbar.
How to Convert Using an Online Tool
The easiest way is to use a free online converter. Here’s a simple process:
- Find a Converter: Go to a website like Convertio or ICOConvert. These are reliable and don't require any software installation.
- Upload Your PNG: Click the upload button and select the PNG file from your computer. Most tools also support drag-and-drop.
- Choose ICO as the Output: Make sure the tool is set to convert to ICO format. Sometimes you need to select it from a dropdown menu.
- Convert: Hit the "Convert" or "Start" button. The tool will process your image.
- Download: Once it's done, a download link will appear. Click it to save the new ICO file to your computer.
That's it! You now have an ICO file ready to use.
Important Things to Keep in Mind
- Transparency: If your PNG has a transparent background, make sure the converter you choose preserves it. Most good ones do.
- Size Matters: ICO files work best with square images. Common sizes are 16x16, 32x32, 48x48, and 256x256 pixels. Some converters let you pick which sizes to include in the final ICO.
- Quality: Converting from PNG to ICO is usually lossless for simple icons, so you don't have to worry about losing quality.
Other Ways to Convert
If you prefer not to upload your files online, you have other options:
- Use GIMP (Free Software): GIMP is a powerful, free image editor. You can open your PNG, export it, and choose the ICO format from the list.
- Command Line Tools (For Developers): If you're comfortable with the command line, tools like ImageMagick can do this conversion quickly. Here's a basic command:

Frequently Asked Questions
Is converting PNG to ICO free?
Yes, most online converters are completely free to use for basic conversions. Some might have limits on file size or number of conversions per day.
Can I convert ICO back to PNG?
Absolutely. The process is very similar. You can use the same online tools, but just select ICO as your input file and PNG as the output format. Our PNG to JPG tool also handles similar conversions.
Why is my ICO file not showing up correctly?
This is often due to the image size. Windows needs specific dimensions. Try creating an ICO file that includes multiple standard sizes (like 16x16, 32x32, and 48x48). A good converter will let you add these sizes.
Do I need special software to create an ICO?
Not necessarily. Online converters are the simplest way. For more control, free software like GIMP works well. For batch conversions or automation, a command-line tool like ImageMagick is great.
