    Tip: Optimise images

    We estimate potential to save at least 14kB* by optimising images:

    1. maternity-ward-case-... is 302kB and could be 14kB smaller
    2. breakpoint-max.jpg is 221kB
    3. breakpoint-max.jpg is 189kB
    4. 251583093_1311527682... is 185kB
    5. breakpoint-max.jpg is 182kB

    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. city.mp4 is 10.3MB
    2. base.js is 525kB ×2
    3. fa-light-300.woff2 is 190kB
    4. fa-duotone-900.woff2 is 187kB

    There is 1 duplicate resource included on the page.

    The page uses 2 fonts which require 377kB. Could system fonts be used instead?
