How PNG Stores Print Resolution
PNG files do not use EXIF tags by default. Instead, PNG uses a dedicated chunk named "pHYs" (Physical Pixel Dimensions) that specifies pixels per meter. PrintReady parses this chunk directly to provide exact DPI.
Frequently Asked Questions
PNG uses lossless DEFLATE compression, which preserves crisp transparent backgrounds, sharp typography, and solid line art without blurry JPEG artifacts.
