Frequently asked questions

Which image formats can become an ICO?

The tool accepts JPG, PNG, WebP and static, self-contained SVG sources with declared dimensions, up to 20MB, then renders each selected icon size locally.

What is a multi-resolution ICO?

One ICO file can contain several square sizes, such as 16, 32, 48, 64 and 128 pixels, so a viewer can choose the sharpest match. Non-square sources are fitted inside each square without stretching.

Does ICO creation upload my image?

No. Canvas rendering and ICO packaging happen locally, and your image is not sent to a server or persisted.
