Setting image size in GROQ query for Sanity.io

Hey friends- Is there a way to set the image size in a GROQ query? Looked all over the dos and only see image sizing with the URL builder after the asset is fetched. I have a thumbnail component and would love to only grab a small version. Thanks in advance for any help!

You fetch the reference and not the asset, then you can build the url with the wanted size and load the asset

You're only really fetching the image information from groq not a specific size, the url parameters on the image src specify what size image is fetched from Sanity's cdn. (eg.

?w=100

for 100px wide image)
Granted if you wanted to use a url directly from your query result you could do something like this (would need to change based on your schema), I probably wouldn't do this though:

Thank you both for the quick response! I will transform with my url builder- didn't realize that was achieving what I wanted, thought it was just doing a CSS resize
