Chances are, if you’re reading this, you know enough about image compression to know it’s worth researching, but not enough to answer the big question every beginner has: what’s the difference between lossy and lossless image compression? Well, to put your mind at ease, here’s the short answer:
Smooth. Sleek. Efficient. It’s a great feeling to trim the fat, whether you’re outlining your work schedule or simply cleaning your home. But when it comes to your site, removing excess isn’t just for your benefit, it’s best for your visitors and customers as well. Digital image compression, and data compression in general, makes your site run faster with less data to load. That means trimming the fat is better for business.
We now know website speed directly affects both the site’s quality and the user experience (UX), but did you know the Google algorithm also factors in speed when ranking search page results? The significance of site speed only increases as modern users come to expect faster and faster sites, but luckily tech breakthroughs are keeping pace to meet those expectations, namely image compression.
Short answer: Because you really don’t need to.
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 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 in your webpages. Your original pictures are rarely shown to your visitors, but they take a lot of your hosting space.
Here is how our Resize Image function works. Continue reading How to resize large images with ShortPixel
Is there anything more annoying that waiting for a website to load? For website visitors, it can be very very irritating and for sure the longer they wait, the higher the percentage of lost potential customers. If it’s the fault of images on your website, you will not remove them; you will not leave the content itself. Every Internet user knows that images are an indispensable part of the website because they explain much more than words, they are much easier to receive and can be very useful for social media shares. Besides, that images are playing a key role in driving traffic to your website. So now it’s time to ask a question – what role do the pictures on your website have? Are they useful or rather disturbing?
PNG or JPEG? Some bloggers know the answer to this question, and some don’t. The former are not necessarily better than the later, but knowing how to choose the correct image format gives you a competitive advantage.
This article could have been one sentence long: PNG is for text, JPEG is for the rest, but let’s get into some details.
On user came to us and asked why he needs an image optimization plugin. He used to compress his images with an image editor, and he was genuinely interested to find what advantages an automated solution has. To be more precise, he asked “why my way to compress images isn’t the best option?”
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.
Hopefully most of you already optimize the images of your website for better performance. But do you a make the same effort to polish your images for best performance in emails?
You should! Since large images might cause some frustration and disappointment for your email subscribers especially when they open your email on their mobile while they are using slower mobile internet connections.
