How do I create a upload button on SharePoint online

Question

I would like to know how I can create an upload button on a SharePoint page so a user is able to click on the upload button and upload a document. Like this one:

Answer 1

The upload form for a particular library can be accessed from

http://site/_layouts/Upload.aspx?List={ID to the library}

You can get the ID by e.g. going to the Document Library Settings, and the URL should end with List=<ID>. Note, that if the URL starts with %7B and ends with %7D, those are decoded to { and } respectively, meaning you don't have to add the braces to the URL.

When you have your upload URL, you can link it to your desired element such as an image or a text for an upload.

Answer 2

If you are using SharePoint Online, remember to add "15" to the URL prior to Upload. Example: //site/15/Upload=
