How to convert an image to WebP for web delivery
Reduce transfer size without confusing format, dimensions and quality, and retain a suitable source for future edits.
Convert to WebP re-encodes a compatible image as WebP with a quality setting from 1 to 100. It does not intentionally change dimensions. WebP supports efficient compression and transparency, so it can replace JPG or PNG in many modern web uses.
Conversion does not guarantee a smaller file. An already optimised source, a tiny icon or a high quality setting may produce a similar or larger result. Compare bytes and appearance instead of assuming an improvement from the extension alone.
What result to expect
You will download a .webp image with the same geometry and the selected quality.
