ICO File Converter working on Windows PC

If you need a clear app icon and want to convert it to an ICO file, here are two free and easy ways to solve the blurry problem:

Method 1: IcoFX （free ICO converter software)

1. Download and install IcoFX: This professional and free tool is especially suitable for ICO file converter.
2. Import your PNG file: Drag the PNG directly into the software.
3. Adjust the icon size: Windows applications generally require 16x16, 32x32, 48x48, 256x256 and other sizes. IcoFX supports adjusting these sizes one by one.
4. Export as an ICO file: Click "Save as", select the .ico format, and you're done!

The good thing about IcoFX is that you can manually adjust each size to avoid generating blurry icons.

Method 2: Use the free online tool ConvertICO

1. Open the ConvertICO website: A simple and practical online ICO converter tool.
2. Upload your PNG file: Drag it in and upload it directly, supporting batch operations on multiple images.
3. Automatically generate a standard ICO file: It will adjust the size according to Windows requirements.
4. Download ICO file: After the conversion is complete, just save the file.

The advantage of ConvertICO is that it is extremely simple to use, but the resolution of the uploaded PNG should be 512x512 or higher to ensure that the final icon is clear.

If the icon is still blurry, you can use a higher resolution PNG file as the source material (at least 512x512 is recommended). In general, IcoFX is the best choice for offline, and ConvertICO is the fastest online ico file converter  tool. I hope these methods can help you, and I wish you a successful launch of the application you develop soon! 🚀
