Learn how to compress images and JPEG files to reduce file size, speed up your website and maintain image quality.

Figure 1. JPEG 2000 applications. Click here to see an enlarged diagram. The JPEG 2000 standard, finalized in 2001, defines a new image-coding scheme using compression techniques based on wavelet ...

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. Stephen Shankland worked at CNET from ...

Yes, I understand why the initial compression of a bitmap (not necessarily a .BMP) to a JPEG is lossy, via the quantization step after DCT. But if I decompress a JPEG back to a new bitmap, and then re ...

Image compression, once the domain of the PC, is becoming pervasive in embedded environments. This trend is largely a result of the increased processing power and multimedia capabilities of new DSPs.

Mozilla has released an updated version of its JPEG compression tool that shaves down file sizes by 5 percent, a small figure but one that is significant for image-intensive Web services such as ...
