    Tip: Optimise images

    We estimate potential to save at least 25kB* by optimising images:

    1. housing-news.png is 1.0MB
    2. newland-dale-pr.png is 837kB
    3. gas-appliances.png is 742kB
    4. 1940s-market-2024-ca... is 265kB
    5. jobs-fair-730x300px-... is 222kB
    6. 730x300px-website-yc... is 102kB
    7. recruitment-event-1.... is 67kB and could be 10kB smaller
    8. cbc-climate-action-n... is 25kB and could be 14kB 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. widget_iframe.2f70fb173b9000da... is 106kB
    2. modules.20f98d7498a59035a762.js is 96kB
    3. m=el_main is 74kB

    Tip: Limit third-party code

    Here are the largest sources of third-party code:

    1. Twitter uses 296kB
    2. Other Google APIs/SDKs uses 107kB
    3. Google CDN uses 40kB

    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.

    If you use the Twitter widget to load a timeline it may be loading as many as 100 of your recent tweets which may contain lots of images. Try setting 'data-tweet-limit' to the most recent 3.
