    Tip: Optimise images

    We estimate potential to save at least 508kB* by optimising images:

    1. untitled.png is 7.9MB
    2. founders-building-1.... is 694kB and could be 508kB smaller
    3. founders-south-quad.... is 498kB
    4. founders-clock-tower... is 450kB
    5. new-coursefinder-ima... is 409kB
    6. arrivals-weekend.jpg is 270kB
    7. microscope-tinted.jpg is 191kB
    8. foundersdaffodils-we... is 183kB

    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. OpenSans-Italic-VariableFont_w... is 580kB
    2. OpenSans-VariableFont_wdth,wgh... is 529kB

    The page uses 2 fonts which require 1.1MB. Could system fonts be used instead? There are 2 TTF/OTF fonts on the page - WOFF2 versions of these fonts may be smaller.

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Google Tag Manager uses 287kB
    2. seersco.com uses 253kB
    3. Other Google APIs/SDKs uses 181kB
    4. Facebook uses 134kB

    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.
