Frequently asked questions

How do I convert ICO to PNG?

Click “Choose Files” or drag your ICO file onto the page, optionally adjust the settings, then hit Convert. Your PNG file downloads straight from your browser. Nothing is uploaded anywhere.

Is this ICO to PNG converter free?

Yes, completely free with no hidden limits, watermarks or signup. Because all processing happens on your own device, there are no server costs to pass on to you.

Are my files uploaded to a server?

No. The conversion engine runs entirely in your web browser using WebAssembly. Your files never leave your device. You can even disconnect from the internet after the page loads and keep converting.

Is there a file size limit?

We impose no fixed limit. The practical ceiling is your device's free memory, since processing happens locally. Most conversions work comfortably with files up to a few hundred megabytes, and image or document conversions handle much more.

Does it work on my phone?

Yes. The converter runs in any modern browser on Windows, macOS, Linux, Android and iOS. No app installation is required.
