- ✗ No Microsoft Outlook required.
- ✗ No upload to any server.
- ✗ No file size limit.
What Is a PST File? And Why Can't You Open It?
PST stands for Personal Storage Table.It's the file Microsoft Outlook creates on your computer to store everything - your emails, contacts, calendar events, attachments, and tasks. Every time you used Outlook, everything went into this file.
It works fine - until something goes wrong.
Until Outlook stops opening it. Until the file gets too big and starts corrupting. Until you get a new laptop and can't find Outlook anymore. Until you leave a company and need your emails before your account gets deleted. Until you just want your data in a format the rest of the world can read.
Built for Exactly These MomentsDT PST Converter opens the file, reads everything inside, and converts it to whatever format you need - even if Outlook itself can't open the file anymore.
Works on Your PST File
Whatever Condition It's In
Healthy PST File
Your PST file opens fine, but you need the data in a different format or want to move away from Outlook.
Add the file, pick your output format, hit convert. Clean result, full folder structure preserved, every attachment included.
Corrupted PST File
Outlook throws an error. The file won't open. You haven't lost your data - not yet.
DT PST Converter's built-in recovery engine automatically scans and repairs damaged PST file headers before extracting your data. Most partially corrupted PST files can still be fully recovered and converted.
No separate repair tool needed. One tool handles both.
What Format Do You Need Your Emails In?
Not sure which one to pick? The one-line description under each format tells you exactly when to use it.
PST → MBOX
Use this for:
Moving to Thunderbird, Apple Mail, Gmail (local), or any email app that isn't Outlook.
MBOX is the universal email format almost every non-Microsoft client understands.
PST → PDF
Use this for:
Legal records, court submissions, compliance archiving.
Any situation where you need emails to be permanent, uneditable documents that anyone can open.
PST → EML
Use this for:
Individual email files. One EML file = one email.
Works with Thunderbird, Windows Mail, Outlook Express, and nearly every email client on any platform.
PST → MSG
Use this for:
Staying in the Microsoft world but need emails stored outside your mailbox.
MSG is Outlook's native single-email format.
PST → CSV
Use this for:
Contacts and calendar data.
Import directly into Google Contacts, any CRM system, or Excel for reporting.
PST → VCF
Use this for:
Moving your Outlook contacts to a new phone, Gmail, or any modern address book.
VCF is the standard contact card format every device reads.
Four Steps. Done in Minutes.
No account. No cloud. No waiting.
Install on Your Windows PC
Download and install DT PST Converter. No internet needed after installation. No account creation, no sign-up required.
Add Your PST File
Drag in a single PST file or load an entire folder of PST files at once. The tool reads them instantly — regardless of size or condition.
Preview Before You Convert
See all your folders, emails, contacts, and attachments before anything moves. Select only what you need — filter by date range, folder, or item type.
Convert and Download Your Report
Pick your output format. Hit convert. When it's done, download a full report of every item converted, skipped, or flagged.
This Runs on Your Machine.
Think about what's inside a PST file. Years of emails. Client conversations. Personal messages. Legal documents. Financial records. Attachments you forgot existed.
Every online PST tool asks you to upload that file to their server. We don't. We can't - because DT PST Converter runs entirely on your own device. Your data goes from your PST file to your chosen output format - on your machine, under your control, without touching any server that isn't yours.
100% Local Processing
Everything happens on your device. No upload. No cloud. No exceptions.
No Internet Required After Install
Convert offline, anytime, without a live connection.
Auto-Resume on Interruption
Power cut or system restart mid-conversion? It picks up exactly where it left off.
Full Conversion Report
Every item logged - converted, skipped, or flagged. Export it as CSV for your records.
The Situations Other Tools Give Up On
Built for the hard cases nobody else handles.
PST file over 500+GB?
No size limit. Multi-threaded engine processes large files completely - no crashes, no throttling, no splitting required first.
Converting multiple PST files?
Use batch mode. Load an entire folder of PST files and convert them all in one session.
Only need specific emails - not everything?
Filter by date range, folder, sender, or item type. Convert exactly what you need - nothing more.
File partially corrupted?
Built-in recovery mode automatically attempts to repair file structure before extracting. Most partially damaged PST files can still be fully converted.
ANSI or Unicode PST?
Both supported. Old Outlook versions, new ones - doesn't matter.
People Use This for All Kinds of Reasons
Not Just IT Teams
Moving from Outlook to Gmail or Thunderbird
You want your entire email history in your new inbox. Convert PST to MBOX and import it directly — folders intact, attachments included.
Keeping emails after leaving a job
Your company email access ends Friday. Export everything to PDF or EML before it's gone — a permanent record that needs no email client to open.
Old PST file that Outlook refuses to open
The file is too large. Or corrupted. Or you don't have Outlook installed anymore. The converter reads it anyway — even in recovery mode.
Archiving emails for legal or compliance reasons
Convert specific date ranges to PDF. Every email becomes a timestamped, unalterable document — ready for e-discovery, audits, or court submissions.
IT teams doing company-wide migrations
Convert hundreds of PST files in batch mode. Full audit log for every item processed. No manual work per mailbox.
Developers and forensic teams
Need raw access to PST data in structured formats? EML and MSG exports give you clean, individual files for review, analysis, or processing.
