Unattach is a Chrome extension developed by 42nd Universe Ltd that optimizes your Gmail storage by efficiently removing unnecessary attachments while preserving your emails' integrity. With a simple red crossed-over paperclip button added to Gmail's web UI, you can easily access actions like "Remove All Attachments From This Email." This feature removes both inline and non-inline attachments by creating a copy of the email without attachments and moving the original to your Gmail Bin, ensuring all metadata remains intact.

To use Unattach, sign in and grant necessary permissions to your Gmail account. The extension operates on individual emails, displaying the Unattach button in email threads for streamlined attachment management. Remember to refresh existing Gmail tabs after installation for seamless functionality.
