Weppy 1.0.3 (October 13, 2010)

Copyright 2010 Nick Zitzmann. "WebP" is Copyright 2010 Google Inc.

Weppy is a browser plugin set for Mac OS X Web browsers that allows them to display inline images that are in the WebP file format, a new image format from Google. WebP is similar to the well-known JPEG file format, except that WebP images are smaller than JPEG images, and in some cases have better quality.

Here's an example. I took this photo in downtown Vancouver, one of my favorite cities in the world, the last time I was there:

Now, here is the same photo in WebP format (and if this doesn't appear, then you'll need to install Weppy & come back):

As you can see, the images look about the same, but the WebP image is only 65 KB in size (really!) whereas the JPEG is 350 KB, making the JPEG a little over 5.3 times larger. That is a typical result, and that means that using WebP instead of JPEG can save you a lot of bandwidth if you're a webmaster.

Weppy is compatible with all Mac OS X Web browsers that do not use QuickDraw for drawing images. This includes Safari, Firefox, Chrome, OmniWeb, Opera, Camino, and probably others as well. It comes with separate plugins for WebKit-based browsers (such as Safari and OmniWeb) and browsers that only support Netscape plugins (such as Firefox, Chrome, and Camino). Both support hardware-accelerated image rendering in browsers that support CoreAnimation. Both are universal binaries (PowerPC and Intel 32), and the WebKit plugin also supports Intel 64. Both require Mac OS X 10.5 or later.
