At a high level, JPEG is a lossy image compression technique. What you may not realize is that achieving this required a fascinating blend of human perception, ...

Today, we’re going to talk about lossless compression. So last episode we talked about some basic file formats, but what we didn’t talk about is compression. Often files are way too large to ...

Beyond RGB: A new image file format efficiently stores invisible light data New Spectral JPEG XL compression reduces file sizes, making spectral imaging more practical.

Learn about how text, images and sound are represented in binary with Bitesize KS3 Computer Science.

Not every compression method works for every file, and you can increase efficiency by changing the file type, codec, or program used.

The Guetzli project shows there's room to improve the venerable compression tech. Too bad Google's software is slow and not so practical for most sites right now.

Add image compression to the list of nifty applications for metamaterials. Metamaterials guide light waves to create “invisibility cloaks” and bend sound waves to make theoretical noise ...

In image compression, a large file that could be cumbersome to store or share loses a small amount of visual information. This "lossiness" largely preserves the image while vastly reducing its ...
