Select “Any” for the object name as well.
Click “Add” in the “Add ARN(s)” dialog.

Open the S3 Management Console.
Click on “Create bucket”.
Open  S3 Management Console
Enter the desired bucket name. Click here for more info.

Tip: You can use this website to check ping of regions: cloudping.info
If you want your uploaded files to be accessible via URL, ensure that the “Block all public access” option is unchecked.
Click on “Create bucket”.

[Optional] Configure DNS for custom domain

you’re utilizing your own domain, you’ll need to configure DNS. Here’s an example using Cloudflare:

Type:            CNAME
Name:          i
Target: i.example.com.s3.eu-central-1.amazonaws.com

cloudflare

The target should follow the format {bucketname}.{endpoint}. You can locate a list of region endpoints from ShareX’s main window -> Destinations -> Destination settings -> Amazon S3 tab -> Endpoints.

Ensure to check here for further information.

Configure ShareX Amazon S3 settings

• Open ShareX and navigate to Destinations -> Destination settings.
  Select the “Amazon S3” tab.
• Enter the access key ID and secret access key that you previously noted down.
• In the endpoints section, choose the region you selected when creating the bucket.
• Enter the bucket name exactly as you created it.
• For the upload path, it’s recommended to use %y/%mo, which creates sub-folders such as 2020/04.
• If you’re using your own domain, check “Use custom domain” and enter your domain in the text box
• Close the destination settings window.
• In the main ShareX window, ensure Amazon S3 is selected as the destination for image uploader, text uploader, and file uploader.

Now you are ready to use  Amazon S3 in ShareX!
