Why should I use this WebP compressor?

Developed by Google and long touted as a JPEG successor, the WebP format offers lossless compression in addition to slightly superior lossy compression to JPEG. Additionally, it adds the ability to create images with transparency that JPEG lacks.

Compress-Or-Die allows to set the compression strength of the transparency independently from the rest of the quality and to sharpen the color edges, which counteracts the 4:4:4 chroma subsampling that the WebP format lacks. All settings made can of course be previewed in the browser before the graphic is finally downloaded.

There are a lot of articles about online image compression tools in the net, most of them are very superficial. Usually they end with a simple: "It generates smaller pictures, so it's got to be better."

Learn why such statements are most of the time meaningless, understand the technical background, and find out which tool you should use as of today.

Image compression with AI
2023-06-25

Wow! Google researchers have now proposed a new method that combines a standard autoencoder with a diffusion process to recover and add fine details discarded by the autoencoder. Interesting to see the possibilities AI opens up when compressing images.

How Should We Store AI Images? Google Researchers Propose an Image Compression Method Using Score-based Generative Models - MarkTechPost
MarkTechPostA year ago, generating realistic images with AI was a dream. We were impressed by seeing generated faces that resemble real ones, despite the majority of outputs having three eyes, two noses, etc. However, things changed quite rapidly with the release of diffusion models. Nowadays, it is difficult to distinguish an AI-generated image from a […]
