How should I use ShortPixel Image Optimizer and Resize Image After Upload?
Resize Image After Upload (RIAU) is a plugin owned by ShortPixel that does only one but very useful function: resize your images after being uploaded. Say you got a 4000x3000 image: with this plugin you'll be able to upload it and automatically resize it to the size you want, 1920x1920 for instance.
The plugin also allows to convert any uploaded PNG file to a JPG file, which results in a smaller file. In addition, you can choose the JPEG compression level, overriding WordPress'.
ShortPixel Image Optimizer (SPIO) is ShortPixel's main plugin, which optimizes your images, new or existing. It has lots of features, and among them, you can also resize the images, just as RIAU does: Can ShortPixel automatically resize new image uploads?
- If you are using SPIO, you do not need to use RIAU, as you will not get any benefit from it.
- If, for some reason, you want to use both, to avoid any over-compression you will have to set SPIO's compression level to Glossy or Lossless.
