Filter by dates, select results, or Shift-click checkboxes to select a range. Original-file changes require managed local files in Chrome/Edge. Deleting attachments edits their source email; separately saved files are unaffected.

A little room for your archive.

Open .eml, .msg, .mbox, or Outlook .pst exports, or a folder to get started. Read emails and save their attachments without an account or internet connection.

Drag and drop files here.
