What is a PNG file

PNG, or Portable Networks Graphics, is a well-liked raster-based graphics format that's primarily employed for editing photos. PNG is a non-patented picture format that uses lossless compression to preserve the overall quality of images.

A pixel-to-pixel compression supported by PNG preserves the original image quality instead of compressing the entire image at once. PNG's provision for transparency is its main benefit. This means that PNG images' backgrounds can be translucent, allowing us to easily overlay them on any other image.
