WebP vs PNG — Which Should You Use?
Both support transparency and lossless quality — but they differ sharply on file size. Here is how to choose.
PNG has been the go-to lossless format for logos, screenshots and graphics for decades. WebP is Google's modern format that offers the same lossless option plus a lossy mode, usually at a much smaller file size.
For the web, WebP almost always wins on performance. PNG remains a safe universal choice for editing and maximum compatibility with older software.
