Why PNG Is Best for ICO Conversion

When creating favicon ICO files, PNG is usually the most reliable source format.

Why PNG Works Better

PNG preserves transparent backgrounds cleanly.
Sharp icon edges stay cleaner at small sizes.
No extra compression artifacts before ICO packaging.

Recommended Workflow

Prepare a square PNG image (at least 256x256).
Open NoStressICOConverter.
Export a multi-size ICO for best browser compatibility.
