What is this?
WebP is Google’s web-targeted image format from 2010, designed to replace both JPEG and PNG for web delivery. At a quality setting that looks the same to the human eye, a WebP file is typically 25–35% smaller than the equivalent JPEG and meaningfully smaller than the equivalent PNG — the difference between a 2 MB hero image and a 1.3 MB one, which is the difference between snappy and sluggish on a phone connection.
This tool re-encodes a PNG or JPG you drop in as WebP using the browser’s built-in encoder, with a quality slider that re-encodes live so you can find the smallest file that still looks right. The before/after byte readout shows exactly what you saved.
Reach for it when you’re shrinking a screenshot before pasting it into an issue, prepping a blog hero image, or trying to cut the size of a 6 MB DSLR JPG to email without your provider auto-compressing it for you.
