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 ...

TinyPNG is probably the most useful and easy-to-use online image size reducer that can compress up to 20 images at a time. However, the maximum file size is 5 MB. Talking about the image format, you ...

JPG was developed to compress photos with lossy compression, which greatly reduced file sizes–a decisive advantage in the early days of the Internet when storage space and bandwidth were still scarce ...

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 ...

The JPEG format is one of the most widely supported ways to create, edit and save images. JPEG files have relatively small file sizes due to the way the format compresses the data that makes up the ...

In this post, we will cover some of the best ways to compress images without losing quality, either a single image or in bulk, online, or using free Windows software. At times, you might need to ...

A group of researchers at Google appear to have taken a leaf out of HBO comedy Silicon Valley’s book for its latest project. The team has developed a way to use neural networks that mimic the workings ...

Last week, Swiss software engineer Matthias Bühlmann discovered that the popular image synthesis model Stable Diffusion could compress existing bitmapped images with fewer visual artifacts than JPEG ...
