Public File Sharing via URLs

This guide guides you through creating public links for your files stored on Impossible Cloud, allowing you to share them with anyone, even if they don't have an Impossible Cloud account. A public link, or a pre-signed URL, is a secure way to provide access to a specific file in your bucket for a limited time. You generate this link directly from the Impossible Cloud interface, and it can be used by anyone to download the file until the link expires. This is an effective way to distribute files without altering your bucket's overall privacy settings or sharing your access credentials.


  • You have logged in to your Impossible Cloud account.

  • You have files uploaded to your bucket that you wish to share.

Step-by-Step Guide

  1. Navigate to Your Bucket

    • Access the 'Buckets' section on your Impossible Cloud dashboard.

    • Select the desired bucket that contains the file you want to share.

  2. Locate the File to Share

    • Scroll or search for the file in your bucket's object list.

    • Once you have located the file, you’ll notice a 'share' icon to the right of the file name.

  3. Initiate the Sharing Process

    • Click on the 'share' icon.

    • A dialog titled 'Share object with a pre-signed URL' will appear, displaying the name of the object you are sharing.

  4. Set the Expiration Interval

    • In the dialog, you will see an option to set the 'Expiration interval'.

    • You can specify how long the pre-signed URL will be valid, choosing between 1 minute and 12 hours. The time can be set in minute or hour increments.

  5. Generate the Pre-Signed URL

    • After setting the expiration time, click the 'Share' button.

    • A notification will confirm that a pre-signed URL has been generated and copied to your clipboard.

  6. Save and Distribute the Pre-Signed URL

    • Since the link can only be generated once, immediately paste and save it in a secure location.

    • Share the pre-signed URL with your intended recipients. They will be able to access the file until the expiration time is reached.
