Editing PNG files on your Mac is a breeze with the right tools. Whether you need to make simple adjustments or perform complex manipulations, this guide will walk you through the best methods and software options available. We'll cover everything from basic cropping and resizing to advanced techniques like removing backgrounds and adding effects.

PNG (Portable Network Graphics) is a lossless image format, meaning it preserves image quality even after multiple edits. This is a key advantage over formats like JPEG, making PNGs ideal for graphics with sharp lines, text, and logos where preserving detail is crucial.
