Drop in a mix of .eml, .msg, .pst, .ost, and .mbox files, pick PDF, HTML, or TXT, and run the batch locally.

For mixed mail archives

When a legal, HR, or IT handoff arrives as a pile of different mail formats and you need readable PDFs without juggling four separate tools.

How to use it

Add your mail files

Drag-drop or use Add Files for any mix of .eml, .msg, .pst, .ost, and .mbox - folders work too.

Pick output format and mode

Choose PDF, HTML, or TXT, set one file per message or a merged document, and toggle inline images.

Run the batch and verify

Start the queue - containers expand automatically. Open a few files to confirm headers and formatting before you archive the lot.

FAQ

We have a mix of .eml, .msg and one big .pst - can one tool handle all of them in a single run? +

Yes. That is the point of this build - it sorts each file by extension, converts single messages one to one, and auto-expands PST, OST, and MBOX containers into the queue.

Do I need Outlook or Thunderbird installed for the PST and MBOX files to convert? +

No. The app reads the archives directly from disk, so it runs on a clean Windows PC with no mail client installed.

Can I get one merged PDF, or only a separate file per message? +

You can export one file per message or a single merged document, and choose PDF, HTML, or TXT. Confirm the layout on a sample in the trial before running a full archive.
