How do I clear 14.8 GB of Safari storage consumed by file transfer websites on iPhone 13?

I use to use websites like “Sharedrop”, “Snapdrop.io” for file transfer between my iphone and windows computer, but now i see my safari is using 14.8 GB of storage, i have no option to delete whatever is taking up the space. Cleared data and cache still it’s the same. My device “IPhone 13” and IOS version “17.7 (21H16)”. Please Help need urgent Assistance.
