    Tip: Optimise images

    We estimate potential to save at least 161kB* by optimising images:

    1. 399-military.jpg is 99kB and could be 65kB smaller
    2. discover-sessions-ba... is 88kB
    3. 600x300_HomepageStri... is 85kB
    4. YorkTalks%20840x560%... is 84kB
    5. 600x300_60th_banner_... is 78kB
    6. UoY_Equal-Access-Stu... is 76kB
    7. V-P-CO-E-01927-399.jpg is 64kB and could be 49kB smaller
    8. 399-cold-person.jpg is 59kB and could be 39kB smaller
    9. jen-study-abroad-399... is 45kB and could be 9.9kB 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. gtm.js?id=GTM-WXLX54 is 118kB
    2. main.MTdjYzNiZDU2MA.js is 109kB
    3. js?id=G-0E2CPWLEXN&l=dataLayer... is 92kB
    4. fontawesome-webfont.woff2?v=4.... is 78kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Google Tag Manager uses 210kB
    2. TikTok uses 148kB
    3. Facebook uses 131kB
    4. Adobe TypeKit uses 97kB
    5. Crazy Egg uses 38kB

    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.
