    What is a PNG file?

    PNG (Portable Network Graphics) was created in 1996 as a patent-free replacement for GIF. It compresses losslessly with DEFLATE after per-row prediction filters, and supports full 8-bit alpha transparency and up to 16 bits per channel.

    PNG is the right choice for screenshots, logos, interface graphics and editing masters. It is the wrong choice for large photos on the web, where JPG, WebP or AVIF are many times smaller.
