The editor

The website interface, palette controls, packing workflow and payment access are independently developed service features. The MIT license below applies to vendored pixelfx code and its stated upstream contributions, not automatically to the whole website. This is an independent project, not an official patch-gg product.

The separately licensed Patch Pixel gallery font is not included. This site uses Space Grotesk (SIL Open Font License) and system fonts. The upstream code's small bitmap glyphs remain under its source license.

Commercial use & the free export

The watermark and daily limit are policies of this editor’s free export service. Pro removes those service limits; it does not sell exclusive ownership or add restrictions to the upstream MIT effects. Every export ZIP keeps LICENSE.txt and NOTICE.txt.
