When one of my clients posts images on his website, does Webflow downgrade the file so that it doesn’t take up so much space (or to lower file resolution)? My client does not have photoshop and cannot save to web format. But someone has told me that Webflow makes it automatic (just like Wordpress) so that the images don’t take up so much space (so if a client posts images where the weight is 2 MB, Webflow makes it so that they will take up no more than 300 up 500 kb when they are saved on Webflow’s servers - (or Webflow websites) - Is this correct??
Thank you so much for anwer me this question 
While Webflow does optimize static images to be responsive (see article), it does not optimize images uploaded in the Collections Manager (or CMS).
If you client uploads a large file, it’ll still be large. But you can restrict them from doing this. (See article)
You can always ask your clients to optimize their images using tinypng.com first before uploading it to Webflow.
Hope this helps 
Thank you so much @PixelGeek
But it is not true when it is regarding the multi image.
There I can’t set min/max guidelines for the height & width of an image in a CMS collection!
My client have to use a lot of “Multi image”
Why isn’t it the same, regarding the “Multi image”
Please let me know. I have to tell her…
