    Tip: Optimise images

    We estimate potential to save at least 976kB* by optimising images:

    1. books.x459cc892.png is 766kB
    2. homepage-clearing-ba... is 337kB and could be 30kB smaller
    3. pope-francis-1.xefaf... is 323kB and could be 208kB smaller
    4. primary-teacher-trai... is 318kB and could be 75kB smaller
    5. pope-francis-2.xa581... is 312kB and could be 206kB smaller
    6. law-moot.x73d0db22.png is 295kB
    7. nationalsaturdayclub... is 267kB and could be 186kB smaller
    8. sportsjournalismburs... is 212kB and could be 135kB smaller
    9. charlottepurdue2023.... is 196kB and could be 134kB 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. Page is 293kB
    2. widget_v2.334.js is 249kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Google Tag Manager uses 204kB
    2. geckochat.io uses 406kB
    3. TikTok uses 149kB
    4. Facebook uses 174kB
    5. ZenDesk uses 257kB
    6. Optanon uses 239kB
    7. geckoform.com uses 93kB
    8. Recite Me uses 73kB
    9. Hotjar uses 63kB
    10. Google CDN uses 56kB

    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.
