? Frequently Asked Questions
What image size should I upload?
Use a square image of at least 512x512px for the sharpest results. Smaller images will be upscaled and may look blurry at larger favicon sizes.
Why do favicons look blurry or cropped?
Favicons are tiny. Use a simple, high-contrast design with generous padding. If your image is not square, the tool will center-crop it to fit.
Which favicon sizes do I need?
Common PNG sizes are 16x16 and 32x32. Including 48x48, 64x64, 128x128, and 256x256 helps with high-DPI displays, shortcuts, and platform-specific icons.
Do I still need a favicon.ico file?
Some legacy browsers still look for favicon.ico. You can keep one for compatibility, but modern browsers accept PNG sizes declared in link tags.
Is my data safe and secure?
Yes, absolutely! This tool runs entirely in your browser. All data processing happens locally on your device - nothing is uploaded to our servers. Your files and data never leave your computer, ensuring complete privacy and security.
