How does the transparent PNG maker work?

It compares each visible pixel with the selected RGB color. Matching pixels become transparent, and optional smoothing creates semi-transparent boundary pixels.

What does the similar color percentage do?

A higher percentage matches a wider range of shades around the selected color, which helps remove shadows and anti-aliased edges.

When should I use outer pixels only?

Use it when the background color also appears inside the subject. Only matching regions connected to an outer image edge are removed.

Is my PNG uploaded anywhere?

No. Reading, editing, previewing, and exporting happen locally in your browser.

Is the transparent PNG maker free?

Yes. It is completely free, requires no signup, and adds no watermark.
