PNG vs WebP

PNG and WebP can both be used for web graphics, but they have different strengths. PNG is a familiar lossless format with strong support for transparency. WebP can support both lossy and lossless encoding and is widely supported by modern browsers.

Choose PNG for graphics and predictable editing

PNG is often a good fit for screenshots, interface graphics, diagrams, logos, and images where crisp edges or transparent backgrounds matter. Its lossless nature can preserve small text and sharp boundaries without the typical block artifacts of aggressive JPG compression.

Choose WebP for modern web delivery

WebP can be a useful choice when the image is primarily being delivered through a modern website. It can provide smaller files for many photographic and graphic images while still supporting transparency and lossless workflows when needed.

Watch the actual file size

Neither extension guarantees a small file. A very large PNG can remain large, and a poorly chosen WebP quality setting can still produce a file that is bigger than necessary. Compare dimensions, quality, and final bytes together.

Converting between them

If a destination requires JPG rather than PNG or WebP, use PNG to JPG for compatible photographic output. If you need a WebP copy from a JPG source, use JPG to WebP.
