Optimising Images For Web
We recommended you use software such as Adobe Photoshop to optimise your images for the web, making them as small as possible.
- In Photoshop go to
File > Export > Save For Web (Legacy)…
- Proceed to lower the Quality setting if possible, maintaining an acceptable level of quality (larger images can usually handle a higher level of compression than smaller images). Also, keep an eye on the output file size in the bottom left of the Save For Web window (the lower the quality setting the smaller the file size)

- You may want to experiment with
Convert to sRGB- sometimes the image can look washed-out with this unticked.

Once you have saved the image in Photoshop we also highly recommend you use software such as ImageOptim (free Mac OS X app) or Kraken (free online tool) to compress the file further. These tools work by tweaking the compression parameters of the image and removing any unnecessary embedded comments, colour profiles and metadata.
JPEGmini is another good tool for optimising images, but it's not free.
