I wanted a simple way to see my attachments in one place, download the files I wanted to keep, and remove emails with attachments I no longer needed. Gmail search can find emails with attachments, but it doesn’t provide a convenient file-based view.
So I built a browser extension called Mail Attachment Lens. It lets me search and filter attachments, download files, and move the source emails to Bin. It also helped me uncover quite a few attachments I had completely forgotten about.
I decided to publish it in case anyone else finds it useful.
It’s free and open source. There’s no backend, so mailbox data stays between the extension and Google.
