Use the script to send an image from Photoshop to compress-or-die.
Copy it to the Photoshop Scripts folder. Overwrite what’s there if you’re asked.
Windows: C:\Program Files\Adobe\Photoshop CS...\Presets\Scripts
Mac OS X: Applications/Photoshop CS.../Presets/Scripts
Allowed file formats: JPEG, PNG, GIF, WebP, SVG (max. 8 MiB)
Developed by Google and long touted as a JPEG successor, the WebP format offers lossless compression in addition to slightly superior lossy compression to JPEG. Additionally, it adds the ability to create images with transparency that JPEG lacks.
Compress-Or-Die allows to set the compression strength of the transparency independently from the rest of the quality and to sharpen the color edges, which counteracts the 1x1 color subsampling that the WebP format lacks. All settings made can of course be previewed in the browser before the graphic is finally downloaded.
There are a lot of articles about online image compression tools in the net, most of them are very superficial. Usually they end with a simple: "It generates smaller pictures, so it's got to be better."
Learn why such statements are most of the time meaningless, understand the technical background, and find out which tool you should use as of today.
