O_O it performs better than xz

A new alternative to tar.

En résumé: 7-zip avec le format d'archive 7z :)

Dernière modif à la lecture de la page: mars 2023.

Pour vos photos:

• limitez les dimensions, un maximum de 2 000 x 2 000 pixels est largement suffisant;
• utilisez le format JPEG (ou AVIF si vous voulez promouvoir le format du futur);
• réglez la qualité à 75 ou moins (35 dans le cas du format AVIF).

Pour des images non-photoréalistes:

• en général vous pouvez réduire encore plus les dimensions que pour les photos;
• utilisez le format PNG.

Je vais jeter un coup d'oeil au format AVIF :)

Le post décrit ensuite certaines définitions, et comment compresser manuellemenet

The files can be put in a directory (automatically created) with the -e option. So we don't need specific commands (tar, zip, 7z, ...) anymore?

An image compression library in javascript based on the Squoosh tool

Optimizes .mp4, .web and .gif

100% client-side

It reduces the size of SVG, PNG, JPEG, WebP, GIF, and AVIF while also giving you the option to convert to WebP or AVIF.

It optimizes PNG, JPEG, and WebP images
It works with URL too.
Only one image at a time

It optimizes JPEG files by stripping out unnecessary data. But only a single image is uploaded at a time.

It includes about a dozen different settings that let you customize the image quality, size, mime type, and more.

But does not work for images in bulk

Privacy-friendly jpeg optimizer

Convert hundreds of WebP images to JPG/JPEG/PNG/ICO, or any other image formats to WebP in just one click!

Wow

A great PDF compressor that looks OK after reading the Terms and privacy (https://pdfcompressor.com/terms)

Do not compress the data directly but creates a program that can reproduce the data 💥

As an example: Aaprogram able to calculate the Fibonacci sequence is a "compressed" representation of the Fibonacci sequence. We replace the data by code, code capable of reconstructing the data.
They already manage to gain 20% on APKs (Android applications) with Superpack compared to the usual zip compression of APKs.
