Hello! I have seen that mapproxy seem to make the image sizes smaller. When requesting an image directly to the WMS and the same image to Mapproxy, its 2/3 of the WMS image in size.<br>
Is there som builtd in mechanism in MP that compress the image?<br>
Both requested images are png by the way.<br>

What you are likely seeing is PNG-8 <span class="post_prose">color quantization:</span>

I couldn't find it in the MapProxy change log, but I think PNG-8 became default in MapProxy 0.9.0 (the blog post is about version 0.8.x).<br>
