Using WebP on Your Website or Native Apps

JPEG and PNG are the predominant formats used for image delivery on the web. According to a W3Techs survey, 74 percent of the websites worldwide use these formats, and for good reason: They are supported across all browsers. Still, there are newer image formats with better performance and a leading example is the WebP format. Here we'll show how to easily implement WebP in order to reduce your images weight by approx. 30 percent and improve your website and native apps image load time.

The Great JPEG 2000 Debate

JPEG 2000 is an image encoding system that was created by the Joint Photographic Experts Group in 2000 with the intention of superseding the original JPEG standard. JPEG 2000 uses the state-of-the-art compression techniques based on a discrete wavelength transformation, enabling users to implement lossless compressions.

Three different ways to do progressive JPEG encoding

There are two different kinds of JPEG images: progressive JPEGs and non-progressive JPEGs. These categories have nothing to do with the JPEGs’ political beliefs. They’re all about the order in which they’ve been encoded.

Compressing a single-color image in various formats

In part one (One pixel is worth three thousand words) of this turned-to-be-two-part blog post, I discussed one-pixel images and how well different image formats “compress” these images. I was surprised how much there is to be said about the matter. This was supposed to be a short blog post, describing one-pixel images and how they compress, and instead it became a glorious monster (and also a two part blog post…).

How various image formats compress one-pixel images

A couple of months ago while taking a break from implementing cool new features like q_auto and g_auto, I was joking in our team chat about how well various image formats “compress” one-pixel images. In response, Orly — who runs the blog — asked me if I’d write a post about single-pixel images. I said: "Sure, why not. But it will be a very short blog post. After all, there’s not much you can say about a single pixel."

Why JPEG is like a photocopier (generation loss)

If you make a copy of a copy of a copy, the quality will deteriorate with every ‘generation’. This problem is called ‘generation loss’. It is not difficult to understand why this happens with actual copier machines. Scanning and printing are not perfect, being based on noisy sensors and physical paper and ink, and the resulting noise will tend to accumulate.
