Amazon S3 direct file upload from client browser - private key disclosure
...
I think what you want is Browser-Based Uploads Using POST.
Basically, you do need server-side code, but all it does is generate signed policies. Once the client-side code has the signed policy, it can upload using POST directly to S3 without the data going through your server.

Explicitly calling a default method in Java

What's the difference between String(value) vs value.toString()
