Frequently Asked Questions
Use our free PNG to ICO converter. Upload your PNG file, select your desired icon dimensions from the dropdown list (like 32x32), and our tool will instantly generate your ICO file.
Yes! This is the main benefit of using a PNG as your source file. Our tool perfectly retains the alpha channel (transparency) of your original PNG, ensuring your website favicon has no ugly white boxes around it.
The most universally compatible and standard favicon size for desktop web browsers is 32x32 pixels. For maximum compatibility with older browsers, a 16x16 icon is occasionally used, while modern high-resolution screens and desktop shortcuts prefer 64x64 or higher.
No, our converter intelligently handles rectangular images. Rather than squishing or stretching your image, it will scale it proportionately and apply a center-crop so it perfectly fits the square dimensions of an ICO without distortion.
While many modern browsers can display a PNG as a favicon, the `.ico` format is still the only universally supported file type across all environments. Using an ICO guarantees your website's icon will display correctly across all browsers, including legacy versions of Internet Explorer and edge cases.
Absolutely. Your privacy is fully protected. Our converter uses modern HTML5 technology to process your images completely within your own web browser. Your PNG files are never uploaded to any external servers.
