Another advantage: Optimus generates progressive JPEGs and WebP images. Even images exported with the 'Save for Web' function in Photoshop can be reduced by several percent using Optimus. That metadata is not however necessary to display the graphics in a browser.Įliminating superfluous information allows for generous file size reductions: depending on the structure and size of the initial images, reductions of up to 70% are possible – while maintaining similar quality. This includes EXIF and IPTC data that are saved in image files by image processing programs.

Instead of only altering the quality of the photos, the plugin goes even further by removing unnecessary metadata from JPEG or PNG files. Optimus compresses all preview images as well (=thumbnails).įind out more: what makes Optimus one of a kind An important difference to desktop and online optimization tools: Photoshop, ImageOptim, JPEGmin and TinyPNG only treat the original images, since thumbnails are only generated when that image is uploaded to WordPress. The plugin slims down the original image and all preview images of an uploaded image.

In plain terms: the visual appearance of treated images does not change in any way. Optimus targets a lossless compression of PNG images and a slightly lossy compression of JPEG images of media uploaded to WordPress - while focusing on protecting your data.
