At its core, a PNG (Portable Network Graphics) file is a container for a lossless raster image. Unlike JPEG, which discards color information to save space, the PNG retains every single bit of data. However, "lossless" does not mean "optimal." When a graphic designer exports a PNG from software like Photoshop or GIMP, the resulting file is often bloated with metadata, unnecessary color profiles, or inefficient compression chunks. A PNG-to-PNG conversion, using tools like pngquant , OptiPNG , or TinyPNG , re-encodes that same image data more intelligently. It might reduce the color palette from 16.7 million colors to 256 if the image is a simple logo, or it might use a better deflate compression algorithm. The result is a smaller file that is, pixel-for-pixel, identical to the original.
