Test of Webp file format 01
Test of Webp file format 01

Zoomed in to 50%, and viewed with IrfanView after installing the webp codec from Google here: developers.google.com/speed/webp/download

JPG saved at 70% on the left, and Webp at 70% on the right.

Initial impression is that the two are nearly identical. The original file was 5.22 MB and was shot with a D300 from a ferry using a 70-300 VR lens at F11 and ISO 200.

Deeper inspection shows a clear reduction in detail on the Webp file - you can see in the JPG that there's a loss in most of the details along the wooden shingles and in a few other places. On the flip side, the sky is much smoother with no jpg artifacts munging up the blue gradient.

The Webp file is 332KB and the JPG file is 847KB at a full 4288 x 2848 size. That's a 60% savings in size for Webp.
