How do I edit an AWS S3 Bucket Object?

I'd imagine this is a really dumb question considering I cannot find a single thing about it

I followed Amazon's instructions for hosting a static webpage: http://ift.tt/1hhcmMb

Now I want to update that static webpage, what is the easiest way to do that?

• Is there a sync client?


• Can I open the files on AWS somehow?


• Do I need to download the file, edit it, and re-upload it? That seems really slow
