What PST to PDF Converter Software does.

What PST to PDF Converter Software does

Easy to use PST Viewer.

  • Works without Outlook. PST to PDF Converter Software uses it own engine to read and analyse .PST and .OST files.
  • Keeps the HTML layout. It renders each email keeping original HTML formatting, fonts, and inline images.
  • Built for many GB archives. A mailbox with tens of thousands of messages opens and exports in a single batch.
  • PDF by default. You may also save into HTML for publishing or into TXT for editing or summarizing by LLM.

Online PST to PDF converters often ha input file size imits like 200 Mb. It is not an easy to fine one that will support 1Gb database. In most cases they have limited folder preview and email filtering, searching and selection capabilities that do not allow you to extract only emails you really need.

Who reaches for it

Legal and eDiscovery

Counsel and review teams turn a custodian's archive into court-ready PDFs on a clean review box. Folder selection keeps the export inside the matter's scope, not the whole mailbox.

IT and HR

Open the .pst a departed employee left behind, export the folders that matter, and hand back readable PDFs. It needs no mailbox login or Exchange connection.

Personal archives

Keep an old Outlook backup you can still read a decade from now. A PDF opens on any phone or laptop, while a raw .pst needs Outlook or a dedicated viewer.

🙋 Frequently Asked Questions

No. The libpff engine reads the saved .PST or .OST on its own, so the converter works on a machine that never had Outlook. You only need the archive file.

Short answer: inline images embed into the PDF when you turn that option on. Long answer: separate file attachments depend on how each message exports and are not guaranteed inside the PDF, so treat attachment embedding as best-effort, not a hard promise.

No. Everything happens on your computer, and nothing is sent to a server. For HR or legal mail, that is usually the deciding reason to pick a desktop tool over an online one.

Yes. The tree has checkboxes, so you can grab just Inbox and Sent, one subfolder, or a filtered set of messages instead of the entire archive.

It saves to PDF, HTML, and TXT. PDF suits sharing and archiving, HTML preserves the original formatting for the web, and TXT gives you plain text for search or other tools.

No. It works on one archive per session, and opening a new file replaces the current one. For separate .EML or .MSG files, SoftOrbits makes dedicated EML to PDF and MSG to PDF converters.

Yes. An orphaned .OST offline-cache file, the kind left over when a mailbox is gone, opens the same way as a .PST.

Short answer: it needs no Outlook and converts whole folders at once. Long answer: the Acrobat plug-in and Microsoft Print to PDF both need Outlook open and handle one message at a time, so a few thousand emails turns into a few thousand clicks.

If the archive is locked and the engine cannot open it, you get a clear error rather than a silent failure. Standard, unprotected .PST and .OST files convert normally.
