The biggest kit in the network. Compress, resize, crop and watermark; convert PNG to JPG, WebP, AVIF, PDF, ICO, BMP, TIFF or SVG and back; hit an exact file size in KB; build a favicon set or an OG image; read the raw chunks of a file that will not open. Every tool takes a batch, and the pixels never leave the tab.
What this kit does that a general converter doesn't.
Batch by default, and it goes deeper than the pixels — chunk viewer, PNG validator, perceptual-hash duplicate finder, real pHYs DPI writing.
