How to Make an ICO File

Need to make an icon in the Windows ICO icon format? If you are designing an application for Windows, a website, or just want to personalize your Windows desktop, you can create ICO files using an image converter website, MS Paint, Mac Preview, or a Photoshop plugin. We'll show you the easiest ways to create Windows icon files on your PC or Mac.

Online File Converter

Open https://www.icoconvert.com in your internet browser.

Icoconvert is a free online image converter that allows you to upload images and convert them to ICO files. It also has options for creating a style for the ICO image as well as allowing you to save the image as multiple sizes in one file. This allows the image to scale to different sizes depending on its use.

  • Other image converter sites that work similarly include ICOConverter (https://www.icoconverter.com) and Online-Convert (https://image.online-convert.com/convert-to-ico).
  • You can use online file converters in all desktop and mobile internet browsers.

Click the Choose File button and select an image.

This button is under the “Step 1: Upload an Image” heading at the top. It will open your file navigator window, and allow you to select your image. Use the navigation window to navigate to the image file you want to select. Then click .

Click Upload.

It’s the large file below the “Choose File” button. This uploads the file to the website. Allow a few minutes for it to complete.

Crop the image (optional).

You will see a preview of the image below the “Step 2. Crop your image” header. Cropping your image allows you to trim the excess areas around the image that you don’t want to use. If you want to crop your image, click and drag a square around the area of the image you want to keep. You will see a dotted line around the area you want to keep.

Select a style (optional).

Icoconvert.com now allows you to select different styles for your ICO images. These styles are different image shapes and borders. To select a style, scroll down and click the styles you want to use below the “Step 3. Apply Styles” header. You can select more than one style.

Select an icon format.

Click one of the radio options below “Step 4. Select the icon format” to select a file format. Your options are as follows:

  • PNG: Select this option if you want to convert the image to a PNG file (not an ICO file).
  • ICO for Windows 7, Windows 8, Vista, and XP: Select this option if you want to convert the image to an ICO file for Windows applications.
  • Favicon for your website: Select this option if you want to convert the image to an ICO file to be used in web browser tabs for a website.
  • Custom sizes: Select this option to create a custom-size ICO image file. ICO files can be multiple sizes that scale to fit their use. If you want to keep the ICO file the same size as the image you uploaded, select “Custom sizes” and then click the radio option next to “Original Size.” If you want to adjust the file size or create a scalable ICO file, click the radio option next to “Multi-size in one icon” and then click the checkbox next to all the sizes you want the ICO file to be able to take.

Click Convert ICO.

It’s the first button below “Steps 5. Convert and Download.” This converts the file you uploaded to the image file that you selected.

  • Alternatively, you can click PNG to ICO to convert a PNG file to an ICO file. Click Resize image to change the image size. Click Compress image to make the image file size smaller, and click PNG to SVG to convert a PNG file to a scalable vector graphic file.
