Frequently Asked Questions
What is the ICO format used for?
ICO is primarily used for website favicons (the small icon in browser tabs) and Windows application icons. It's the standard format recognized by all browsers and Windows systems.
What size should my favicon be?
The most common favicon sizes are 16x16, 32x32, and 48x48 pixels. For best results, start with a square PNG image at least 48x48 pixels. Many modern sites also include 192x192 for Android and 180x180 for iOS.
Does ICO support transparency?
Yes, ICO fully supports transparency. If your PNG has a transparent background, that transparency will be preserved in the ICO output.
Can I use the ICO file as a favicon?
Yes! Simply name the file favicon.ico and place it in your website's root directory. Most browsers will automatically detect and display it.
Is my data secure during conversion?
