Frequently asked questions
What is an ICO file?
An .ico is a container format that holds one or more small images at different sizes. Browsers and Windows pick the best size automatically, which is why a real .ico beats a single PNG as a favicon.
Are the entries inside really valid?
Yes. The file is built with correct ICONDIR and ICONDIRENTRY headers, and each size is stored as a PNG-compressed entry — the modern standard every browser accepts.
Is my image uploaded anywhere?
No. Everything — rendering each size and packing the binary container — happens in your browser. Your image never leaves this page.
