If you have hundreds or even thousands of existing images on your website, the Bulk Optimisation option lets you edit and compress as many images as you need together. You can also set-up Auto-Optimise, where the plugin will automatically compress your images as and when they are uploaded.
If you’re running into timeout issues in the process of sending large images to be processed, you can use the “’UPDRAFT_TASKS_LOCK_TIMEOUT’” constant of WP-O Image Optimisation to adjust the timeout period for optimisation API requests.
define(‘UPDRAFT_TASKS_LOCK_TIMEOUT’, 60);
Since WP-O only employs lossless image optimization by default, the optimization value depends on the amount of (unnecessary) metadata saved in the image and the composition of the image itself. The more metadata can be removed from an image, the higher the reduction that can be achieved through optimization.
Should you wish to uninstall the plugin, you can rest easy in the knowledge that all the images you compressed will be unaffected and will remain on your site. WP-O optimizes and replaces the images but does not host them, allowing you to maintain full control over your content.
We know that everyone has their favourite kid of images to work with, which is why WP-O allows you to optimise NG, JPG, GIF, BMP and TIF pictures up to 5MB in size. We use the latest cutting edge technology to compress your images, including PNGQuant (to strip unneeded chunks from PNGs), JPEGOptim (to provide lossless optimization) and OptiPNG (as a PNG reducer).
