How to create a vector conversion web application?

I am wondering if there is a way to create a web application that allows the user to attach a raster image file such as a jpg or jpeg and download a vector image with ImageGraphics. I have figured out everything except how to let the user download the output of ImageGraphics to their computer. I have searched "Download" in the documentation center and I wondering if there is a way to create a button that will download the output file if they click on the button, similar to the function ClickToCopy. I do know that I can create a separate cloud expression link and then that will have a download button for make my own copy but I am wondering if there is a way for something such as ClickToDownload without redirecting.

I have made some changes but this code fails with the automatic download. Sometimes when I deploy the code to the cloud I have a white screen and there is no app. CloudDeploy[ FormFunction[{"x" -> Interpreter[Restricted["UploadedFile", "Image"]]}, ImageGraphics@Import[#x] &, "PNG"], FileNameJoin[{$CloudRootDirectory, "vector image.svg"}], Permissions -> "Public"]

CloudDeploy[

Interpreter[Restricted["UploadedFile", "Image"]]}, 
ImageGraphics@Import[#x] &, "PNG"], 
FileNameJoin[{$CloudRootDirectory, "vector image.svg"}], 
Permissions -> "Public"]
