YOGA Image Optimizer v1.1.0 Released: Improved JPEG Optimizations, Resize, Multiselection, Settings,...

Main Changes

Improved JPEG Optimizations

In the v1.0.0, YOGA relied only on Guetzli to optimize JPEGs. Now it also uses some optimization from MozJPEG to improve the compression. Thanks to this, JPEGs are now from 2.4 % to 7.3 % smaller, without additional quality loss.

YOGA v1.0.0 vs v1.1.0 on JPEG optimization

This version also adds support for JPEG orientation metadata to avoid having the image wrongly rotated after being processed by YOGA.

Image Resize

YOGA Image Optimizer now allows to resize images. Please note that it can only reduce images' sizes, and that it will always preserve the ratio.

Multiselection / Batch Edition

The multiselection was a highly asked feature, so it is now possible to select multiple images and change their property at the same time.

Settings

YOGA Image Optimizer is now configurable. You can now

• set how many threads to use for optimizations,
• select your favorite GTK theme (mostly useful on Windows),
• and choose the default name of output files.
