Hongkiat: Minify & Optimize JPG Images Online with Jpeg.io. “The free tool Jpeg.io lets anyone convert their existing images into optimized JPEG files without any software. You simply upload your images and the website does everything for you on the backend.” Decent overview of how it works.
How-To Geek: Why Your Facebook Photos Look So Bad (And What You Can Do About It). “In the image above, you can see a side-by-side close up of the original photo and the version that’s on Facebook. The difference is noticeable. And Facebook is going to make some changes to pretty much any photo you upload in order to compress them so they load faster. There’s nothing you can do to totally stop this—if you want a high quality photo sharing site, check out something like 500px—but you can at least minimize the drop in quality when you upload pictures. Let’s look at how.”
Digital Trends: JPEG vs. PNG: Which image-saving format is the better one to use?. “In the world of digital imaging, there are two image formats that prevail above all else: JPEG (or JPG) and PNG. At first glance, a single image shown in both formats might seem identical, but if you look close enough, and dig into the data, there is quite a difference between the two images. Further, each format is designed to be used in specific ways to make the most of its strengths and weaknesses. To help you better understand the differences, we created this guide on JPEG vs. PNG to help you know when to use which format.” Good overview.
Quartz: How do we make the internet faster? Let algorithms bicker over what we send. “The internet has become a visual place—with companies like Snapchat, Facebook, and Google reinventing their services around your phone’s camera. As a result, the need to relay visual information with less data is becoming increasingly important. Artificial intelligence may solve that problem.”
Barbara Feldman: 3 Easy Ways to Compress Images that are Too Big to Upload to WordPress. “In order to control site loading times, disk space used, and as a security measure, WordPress limits the file size of any image uploaded to the Media Library. The default maximum size is 2MB. You can change this limit (in php.ini, .htaccess, or wp-config.php) if you wish, but that’s a lesson for another day. Here are three free online tools for optimizing images that are too big to upload.”
CNET: Google works to make JPEG graphics smaller but not sucky. “Google thinks it’s found a better way to compress JPEG. In research published Thursday, it details technology called Guetzli that cuts JPEG file sizes by 35 percent in its testing. The idea isn’t to replace JPEG, but tweak its settings to minimize the likelihood we’ll notice problems when files are squeezed.”
Twitter is having trouble on all kinds of fronts put apparently it’s getting really good at compressing images. “Twitter has long been interested in compression—more than 300 million tweets are sent each day, many of them with attachments. In June, Twitter acquired Magic Pony Technology, an artificial-intelligence startup focused on making pictures look better at smaller file sizes, to jumpstart its machine-learning team. That team, now known as Twitter Cortex, earlier this month announced one of its first major successes: a machine-learning algorithm that can compress a photo more efficiently than JPEG2000 (an industry standard more modern but less common than just JPEG). Put plainly, that means sharper pictures that take up less space.”
