From export to new mailbox in one go

Most mail programs can save mail in a format we read. Gmail exports mbox through Google Takeout (upload the .zip or .tgz as it is), Apple Mail has Export Mailbox, and Thunderbird already stores every folder as an mbox file in your profile. Classic Outlook for Windows exports a .pst through File → Open & Export → Import/Export, and legacy Outlook for Mac exports an .olm through Tools → Export. EML files, Apple Mail's EMLX library and Maildir folders work too.

Step-by-step instructions: Gmail, Thunderbird, Apple Mail, Outlook for Mac, Outlook for Windows.

Sign in and start a new conversion. Choose what you want back: a PST for Outlook, MBOX for Thunderbird and Apple Mail, EML files, PDFs or a CSV. Then drag in your files, whole export folders or zip and tar archives. We walk the folders for you and skip index and metadata files such as Thunderbird's .msf or Apple Mail's Info.plist. You can combine several mailboxes into one conversion.

Name the result (Outlook shows a PST's name in the folder pane) and choose how folders are built. The total size and the matching price update as you add files. The price tiers are the same whichever format you choose.

Your browser uploads each file directly to private, encrypted cloud storage over HTTPS. Large files are split into parts that upload several at a time, and a part that fails is retried automatically. Keep the tab open until the upload finishes. You can see progress for each file and for the whole upload.

When the upload is complete you're sent to Stripe's secure checkout for the one-time price. Free tiers skip this step. As soon as Stripe confirms the payment, your conversion is queued.

A dedicated, isolated worker downloads your files, reads every message and writes the format you chose. The job page shows messages converted, percentage and an estimate of the time left. You can close the tab and come back later. When it finishes you get a summary: messages, attachments, folders, any messages that needed special handling, and any non-mail items (contacts, calendar events, tasks) that were skipped. PDFs are made without loading remote images.

Download the result from your dashboard: one .pst file, a .zip of MBOX, EML or PDF files, or a .csv. It stays available for 7 days, and you can download it as many times as you need in that time. After that it is deleted automatically. You can also delete it yourself straight away.

In Outlook for Windows use File → Open & Export → Open Outlook Data File or Import/Export. Outlook for Mac imports PST files through File → Import. See the Outlook import guide for every version, including the new Outlook.

MBOX files import into Apple Mail with File → Import Mailboxes, and into Thunderbird with the ImportExportTools NG add-on. EML and PDF files open with a double-click, and the CSV opens in Excel.
