The most universally compatible and standard favicon size for desktop web browsers is 32x32 pixels. For maximum compatibility with older browser versions, a 16x16 icon is occasionally used, while modern high-resolution screens prefer 64x64 or higher.
ICO files must be perfectly square (e.g., 32x32). If you upload a heavily rectangular PNG image, the image may be squeezed or padded to fit the square box. For the very best results, crop your PNG into a perfect square before uploading it to the converter.
The ICO format is a specialized computer graphics file format designed for computer icons in Microsoft Windows. On the internet, ICO files are primarily used as "favicons"—the tiny branding logos that appear next to a website's name in your browser tab.
Yes, it is completely secure. Your files are uploaded via an encrypted connection, processed in a secure temporary folder, and then automatically and permanently wiped from our servers immediately after the conversion.
