  Tip: Optimise images

  We estimate potential to save at least 1.5MB* by optimising images:

  1. _rcmjdoboe.jpg is 1.1MB and could be 757kB smaller
  2. _rcmjdviolin.jpg is 388kB and could be 101kB smaller
  3. Discover%20thumbnail... is 354kB and could be 229kB smaller
  4. International%20Stud... is 263kB and could be 64kB smaller
  5. Christmas%20Card%20h... is 246kB and could be 172kB smaller
  6. _twopeopleinmuseum.jpg is 192kB and could be 65kB smaller
  7. _museummusic5.jpg is 170kB and could be 11kB smaller
  8. Strings%20Double%20B... is 168kB and could be 43kB smaller
  9. QAA_Quality_black.jpeg is 50kB and could be 19kB smaller

  First, check that images are appropriately sized - you most likely don't need a 6000x4000 pixel image straight from a digital camera. In Windows, the Photos software will let you quickly shrink huge images and will give you an improvement.

  Next you could try using tinyjpg.com (JPG image) or tinypng.com (PNG image) to further optimise your image. This will strip out metadata that may be taking up lots of space.

  *This is an estimate from Google PageSpeed and you may get much better results than this in practice.

  Tip: Large files

  Aside from images, here are the biggest resources:

  1. jqueryui.js is 539kB
  2. collected.css is 134kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Civic uses 96kB
  2. Google Tag Manager uses 86kB

  Third-party code can significantly impact load performance. Limit the number of redundant third-party providers and try to load third-party code after your page has primarily finished loading.
