How to change compression of WordPress uploads including original image

We are currently using this to change the compression used on jpgs when uploaded to the WP media library: add_filter(‘jpeg_quality’, function($arg){return 75;}); However, this does not compress the original image.

Autogenerated Thumbnail compression depending on size

Theme compression/ minifying or W3 Total Cache – which should I use?

I run a WP3.x Multisite setup. One of the themes I use on a site has options for minifying, using Gzip compression and using data URIs for images (not sure what the latter function is or does). In the past, I have used W3 Total Cache, in combination with Cloudflare. What is the best practise […]

How to keep WP from recompressing Full Size images

I have noticed that WP does have the bad habit of recompressing Full Size images during uploads. I mean, it does make sense creating several smaller versions of each uploaded image, applying a default 90% JPEG quality setting, but why compressing twice also the Full Size images, as they are fine just as they are?
