Frequently Asked Questions
Can I make a good favicon from a JPG photo?
Yes, but simple images work best at small icon sizes (16x16, 32x32). Detailed photos may lose clarity when shrunk to favicon dimensions. Consider cropping to a recognizable portion of the image first.
What is the best image size for creating an ICO?
Start with a square image, ideally 256x256 pixels or larger. The converter will resize to standard icon dimensions. Non-square images will be cropped or padded, so square source images produce the best results.
Can I add transparency to my favicon?
JPG does not support transparency, so your ICO will have a solid background. For a favicon with a transparent background, start with a PNG file instead and use the PNG to ICO converter.
