Upload File to AWS S3 Easily

Whether you’re a beginner or an advanced user, uploading files to Amazon S3 shouldn’t be a challenging task. In this article, we have described one of the easiest methods you can use to upload any type of file, be it images, audios, or videos to the AWS S3.

Uploading Files to Amazon S3 Using Native Methods

Amazon S3 is an object storage platform, which stores your file as an “object.” It contains the file’s data and its metadata and is stored in a “bucket,” a container that is capable of holding an unlimited number of objects. There are two ways to upload a file to Amazon S3:

  1. S3 Console – The S3 console is usually the default method to upload files to S3 for many people. You can create folders in the console and then store objects in those folders. The name of the folder appears as a prefix in the object’s name.
  2. AWS Command Line Interface (CLI) – The AWS CLI provides more control and flexibility when uploading files to S3. For example, you can upload a file that’s larger than 160 GB (which is normally the limit imposed on an individual file). To upload a file to S3 without console access, you have to use the “put-object” command.
