Frequently Asked Questions

Which sizes does the ICO generator produce?
16×16, 32×32, 48×48 and 256×256, packaged in a single .ico file covering browser tabs, desktop shortcuts, taskbar and high-DPI displays.
How do I make a favicon for my website?
Upload a square image, generate and download the .ico, place it at your site root as favicon.ico — browsers pick it up automatically; explicit HTML referencing improves compatibility.
ICO vs PNG icons?
ICO is the native multi-size container for Windows and browsers with the best compatibility; PNG is lighter for direct web use but has limited multi-size support.
Does ICO generation lose quality?
Small sizes (16px/32px) resample with square center-crop to keep the core visible; 256px stays sharp. Overall output looks professional.
Is online ICO generation safe?
Safe. Processing runs fully in your browser; images never upload, suitable for unpublished brand logos and project assets.
What is the ICO generator best for?
Website favicons, Windows app icons, folder icons, desktop shortcuts and dev-project branding needing multi-size compatibility.
Are there limits on free use?
No. Free, no registration, unlimited, accepting PNG/JPG/WebP and outputting standard .ico.
Any requirements for the uploaded image?
Use a square image (256×256 or larger) with centered content so the icon stays recognizable at every size.
