Our artificial intelligence compression algorithms compare each and every optimized image with the original and make sure that they are looking good for a human visitor. Moreover, we have three sets of algorithms for three different user cases: Lossy for most of the sites, Glossy for photographers, and Lossless for those rare situations when you cannot lose a pixel.
If you are used with offline tools like Adobe Photoshop, you could expect to find similar settings in our plugin menu. Or in our online image optimization tool for that matter. That’s why we are asked from time to time if there is a way to set the compression ratio.
ShortPixel’s Resize Images feature can reduce your hosting storage by changing the sizes of your uploaded pictures. Each time you add an image WordPress automatically generates a number of thumbnails which are deployed on your webpages. Your original pictures are rarely shown to your visitors, but they take a lot of your hosting space.
Guetzli is the new JPEG encoder developed and released as open source by Google. It is designed to produce ~35% smaller files, without compromising the picture quality. We, at ShortPixel, had recently our own update: ShortPixel Glossy optimization, the lossy new algorithm for photographers.
Testing Guetzli algorithm was mandatory for us. When you are in the image compression business, you need to get your hands on any brand new innovation and see what it can do.
How does Guetzli compare with ShortPixel’s new Glossy image optimization algorithm in terms of quality and performance? Can we use it alongside our algorithms? Does it have practical value for our users?
ShortPixel introduces a new image optimization option called Glossy. The new feature is a lossy optimization algorithm calibrated for the photographer’s needs. We still recommend Lossy for the most user cases, because it has the best balance between image optimization and picture quality.
Immediately after setting up your free ShortPixel account, you are given 100 ShortPixel credits. Each credit allows the automatic processing of one image or thumbnail (or PDF) from your WordPress web site (or sites as you will learn below). Each and every month, regardless of whether you purchased a stack of credits from the “one-time payment” section (below the monthly and yearly plans in the ShortPixel.com Control Panel), you are given an extra 100 credits to use for free. In addition, you can get an extra 100 credits per month for every person that you refer.
