  Tip: Optimise images

  We estimate potential to save at least 3.6MB* by optimising images:

  1. 53218281282_0ba95c16... is 3.0MB and could be 2.4MB smaller
  2. 52169322768_4eddba5e... is 738kB and could be 578kB smaller
  3. 52153168963_f0ed3001... is 291kB and could be 143kB smaller
  4. 52152154112_02ec5d56... is 287kB and could be 157kB smaller
  5. 52153161721_23f407b0... is 256kB
  6. 52153659840_c0181ec1... is 249kB and could be 127kB smaller
  7. 52153168938_9131dffb... is 247kB and could be 43kB smaller
  8. 52152154087_9a7f36a3... is 241kB and could be 43kB smaller
  9. 52152154062_a892fa53... is 219kB and could be 64kB 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. player.js is 226kB

  Tip: Limit third-party code

  Here are the largest sources of third-party code:

  1. Vimeo uses 2.1MB
  2. Flickr uses 8.9MB
  3. Google Tag Manager uses 146kB
  4. Google Fonts uses 84kB
  5. Cloudflare CDN uses 73kB
  6. New Relic uses 60kB
  7. jQuery CDN uses 31kB

  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.
