The WebP Image Format

Posted in Editorial with tags , , , , , , , on April 25, 2013 by Art of Photography

Did you know there is a new image format in the digital world? Google released *.webp in November of last year as a way to store images in a smaller file size. While the format is more efficient than JPEG (25% to 34% smaller), it has the same abilities as PNG and GIF (Lossless & lossy compression, alpha channels, and animation support). So far this new format is only intended for the web. It is supported (meaning you can see pictures formatted this way) in Chrome and Opera. Facebook recently switched to this format which caused some users concern for images that suddenly didn’t render (looks like they have switched back).

Can you see this (a webP formatted image)?

Google provides a plug in for Internet Explorer, and Android (Ice Cream Sandwich) via their Frame plug-in. They also offer a WebP converter (free download) for Windows, Linux, and Mac OS X. Other software that can convert these files includes Picasa, Pixelmator, ImageMagick, Konvertor, ReaConverter, XnView, and of course my favorite, IrfanView! There are also free plug-ins for Photoshop and GIMP too (if history is any example, expect Photoshop to soon have a Camera Raw update for this).

It will take time but I think this format is going to catch on. Google does not restrict its use and it will make web pages load much faster (think phones). In the example above (that you may or may not see) the original jpg version was 443 KB jpg while the webp version in the link is only 213 KB.
