Quality note

Best results usually come from clear subjects, decent contrast, and desktop-class devices for heavier images.

For humans and agents

A premium browser workflow for people, with a flow simple enough to work well in lightweight agent usage too.

PNGmaker is optimized for humans first, but the structure is intentionally clear: upload, process, compare, download. That makes it easier to operate both manually and from browser-based agent workflows.
