JPG to ICO — FAQ

Can I use a JPG photo as a Windows icon or favicon?+
Not directly — Windows and browsers require ICO format for icons and favicons. Converting your JPG to ICO makes it usable as an app icon or browser favicon.
Will my JPG background become transparent in the ICO?+
No. JPG doesn't support transparency, so the ICO will have a white or solid-colored background. For a transparent icon, start with a PNG source that has a transparent background.
What size should my JPG be for a good ICO?+
Use a square JPG at least 256×256 pixels. The converter will produce the ICO at the appropriate size. Non-square images will be centered on a square canvas.
Is this ICO suitable for use as a favicon?+
Yes. The output ICO works as a standard browser favicon. Add <link rel="icon" href="/favicon.ico"> to your HTML to use it.
What is the best image for a website favicon?+
Use a simple, square image with high contrast that reads clearly at 16×16 pixels. Picovert's ICO output includes 16×16, 32×32, and 48×48 sizes needed by all major browsers. Square JPGs work best — avoid images with fine details that blur at small sizes.
What is the difference between a favicon.ico and a PNG favicon?+
A favicon.ico is a container format that holds multiple sizes (16×16, 32×32, 48×48) in a single file, ideal for browser tab icons and legacy compatibility. PNG favicons work in modern browsers but require separate files per size. Most developers use both: favicon.ico for legacy support and apple-touch-icon.png for iOS.
