ICO File Converter working on Windows PC

If you're finding a ICO file converter on Windows PC, one of the best ICO file converter tools I've come across is IrfenView. Now, I've used this tool quite a bit, and let me tell you, it's pretty solid for handling all sorts of image formats, including ICO. Plus, it’s lightweight and doesn't bog down your system.

Free and Lightweight: It’s completely free for personal use and doesn’t take up much space. You won’t need to worry about trial limits or watermarks.
User-Friendly: The interface is straightforward. You just open your ICO file, and you can save it in different formats like PNG, JPG, BMP, etc. 
Batch Conversion: One of the coolest features is batch conversion. If you have a whole bunch of ICO files to convert, you can do it all at once – saves a ton of time!
Plugins: It supports a ton of plugins if you want to expand its capabilities, making it super versatile.

How to Use this ICO file converter

1. Download and Install: Head to the IrfenView website and snag the installer. Follow the prompts to get it set up.
2. Open your ICO File: Launch the program, drag your file in, or use the File menu to open it.
3. Convert: Go to File > Save As and choose the format you want. Just make sure to check the dropdown for different formats.
4. Save it: Pick the destination and hit save. Easy-peasy!

If you’ve got Windows 10 or later, you can also use the built-in Photos app. It doesn't have as many features as IrfenView, but you can open ICO files with it and take screenshots of the images if you're in a pinch. However, for actual file conversion, it's a bit lacking compared to dedicated tools like IrfenView.
