FAQ

Questions, answered.

How do I convert Gmail Takeout to PST?

Download your Takeout, unzip it, and drop the .mbox file (or the Mail folder) above. Takeout puts all your mail in one .mbox file, which becomes one folder in the PST.

Does it work with Apple Mail?

Yes. In Apple Mail use Mailbox › Export Mailbox, then drop the exported folder here.

Is my file uploaded?

No. The engine runs inside your browser tab and reads the file from your disk. Results are written to your browser's private storage until you save them. Nothing is sent to a server.
