Learn how to choose the best image format for your use case
JPEGs, PNGs, and GIFs — oh my! Most web developers only learn which format to use through trial, error, and long experience, and not necessarily by fully understanding how these formats actually work.
 
In this article, we’ll take a high-level look at each formats’ compression algorithms, in order to understand how their differing strategies make them more or less appropriate for different kinds of images. Then, we’ll tour a few next-generation image formats (like WebP and JPEG-XR) and see how we can use smart servers to take advantage of these powerful (but not yet universally-supported) formats, today.

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."

How to optimize animated GIFs with lossy compression

Animated GIFs keep getting more and more popular, but they are generally very big files with slow loading times and high bandwidth costs, while the format itself is quite old and not optimized for modern video clips. As developers, you need to allow users to upload their animated GIF files, but you also need to deliver them optimized, which can be a complex, time consuming process.
