How to Shrink PNG Files Without Visible Quality Loss Using WebP or JPG

PNG is a lossless image format that preserves every pixel exactly, which often results in unnecessarily large file sizes for everyday use. The most effective way to reduce a PNG's size is to re-encode it into a format that supports quality trade-offs, such as WebP or JPG. WebP is the preferred option because it retains transparency support while typically achieving 60–90% smaller file sizes at around 90% quality with no noticeable visual difference. JPG serves as a fallback for platforms that do not accept WebP, though it cannot preserve transparent backgrounds. For best results, always compress from the original PNG rather than a previously compressed copy.
