Convert PDF file into Bytes[], pass Bytes[] to request

Hi, I have a PDF file in my local machine. I need to convert PDF into Bytes and pass these Bytes to one of the fields in my JSON request body. Can someone please tell me how can I do this with the postman, please?


"Bytes" :"File Bytes",

“Name”: “DamagePackBlobName”,

“Size” :“fileBytes.Length”,

“PackName” : “Constants.DamagePack”,

“FileType” : “fileType”
