Email Converter For Every Mailbox
PCDOTS Email Converter is a complete email conversion tool for Windows that moves your data between 250+ file formats, desktop clients, mail servers and cloud accounts without losing a single attachment, header or folder. Trusted by IT teams since 2005, with a 99.5% conversion success rate across 25,000+ tested mailbox samples.
Most email converter software fails on the cases that actually matter: a corrupt PST file, a Unicode subject line in Cyrillic or Mandarin, malformed RFC headers, a mailbox with thirty levels of nested folders. PCDOTS Email Converter was built around these conditions, not in spite of them, because they are the exact situations that bring a routine conversion job to a halt.
Lossless Conversion Engine
The folder hierarchy, attachments, embedded images, message headers (compliant with IETF RFC 5322), custom flags, read and unread state, sent timestamps and Unicode characters all carry through to the output exactly as they appeared in the source. Every release is regression tested against more than 25,000 real mailbox samples that span every supported format.
Preserves nested folder structure to any depth
Maintains original message timestamps and time zones
Carries attachments without re-encoding the bytes
Granular Selection & Filtering
Convert exactly what you need, nothing more. Select individual folders with a checkbox, filter by date range or sender, exclude attachments above a size threshold, skip system folders entirely. The result is a clean output with no post-conversion cleanup required.
Multi-folder selection with a checkbox interface
Date range, sender, recipient and subject filters
Attachment size and file type exclusion rules
Complete Pre-Conversion Preview
See every email exactly as it appeared in the source client before you start the conversion. Headers, body, inline media and attachments render in a clean preview pane (the same engine powers our standalone PST File Viewer). Trial users can export 10 items per folder to verify accuracy on real data before paying for the full edition.
Full headers and body rendering
Attachment list with size, type and filename
Hex view for byte-level message inspection
Batch Conversion
Queue dozens of source files or accounts in one job. The email converter tool processes them sequentially with a single click and a unified progress bar.
Find any email across thousands of folders by sender, subject, body, date, attachment name or any combination. Results appear in fractions of a second.
Field-Level Extraction
Pull email addresses, attachments and phone numbers separately into TXT or PDF files. Useful for compliance audits, contact list extraction and discovery work.
Direct IMAP & Cloud Export
Skip the local file step entirely. Push converted emails straight into Gmail, Office 365, Yahoo, iCloud or any IMAP server. Folder structure is preserved on the destination side.
Runs Standalone on Windows
No Outlook installation required, no Office license, no Exchange dependency. Works on a bare Windows PC including Windows 11, 10, 8, 7 and every Server release back to 2003.

More Than a Mail Converter, It is a Full Inspection Tool
Beyond simple format conversion, PCDOTS Email Converter doubles as a deep inspection reader, search tool and field-level extractor for any administrator who needs to look closely before they act.
The same engine that runs the email conversion also reads the data underneath. Open any source (file, client or server) and inspect every email in content mode, hex mode or raw mode. Spot deleted or edited content, verify message headers and confirm integrity before you do anything destructive to the original mailbox. For pure inspection work without conversion, see our Email Forensics Investigation tool.
Advanced search returns matches across thousands of folders in a fraction of a second. Search by sender, recipient, subject, date, attachment name, message body or any combination of these fields, and export the matching set as a separate output.

Problems You're Facing
Cannot open a PST file without Outlook installedOutlook is heavy, paid and not always available on the machine where you need to read the data.
Lost attachments or broken folder structure after conversionFree online converters silently strip metadata, drop attachments and flatten your folder hierarchy.
Thunderbird emails stuck in MBOX, no way to reach GmailMBOX is supported by very few cloud destinations directly. Most tools fail mid-transfer or corrupt messages.
Need to convert 50,000+ emails without doing it one at a timeManual conversion is impossible at scale. You need batch processing with proper filters.
Migrating from a legacy server, emails sit in an unusual formatCommunigate, MDaemon, Kerio and Zimbra files are rarely supported by mainstream tools.

FAQs
Common Questions About Email Conversion
Quick answers to the questions IT teams ask most often before downloading the email converter tool.
What is the best email converter for Windows?
The best email converter for Windows is one that supports the widest range of formats, runs locally without uploading data, preserves folder hierarchy and attachments, and works across all Windows versions (11, 10, 8, 7). PCDOTS Email Converter handles 25+ input formats including PST, OLM, MBOX, EML and MSG, has a 99.5% conversion success rate across 25,000+ tested mailboxes, and is rated 4.6 / 5 by 1,408 verified users on G2, Capterra and Trustpilot.
Is there a free email converter that works on Windows?
Yes. PCDOTS Email Converter offers a free trial that converts up to 10 emails per folder across every supported format. The trial is fully functional with no time limit, no credit card and no signup. Free online converters exist but most strip attachments, flatten folder structure and require uploading sensitive email data to a third-party server, which is unsafe for business mail. The PCDOTS trial runs entirely on your PC and lets you verify accuracy before paying for the $49 lifetime license.
Can I convert emails without having Outlook installed?
Yes. PCDOTS Email Converter reads PST, OST, OLM, MBOX and every other supported format directly, with no Outlook installation, no Microsoft 365 license and no Exchange dependency. The converter parses email files at the byte level and renders messages, attachments and headers in a built-in preview pane. This is critical for IT teams that need to read or migrate Outlook data on a machine that does not have Office installed.
How do I convert PST to MBOX format?
Download and launch PCDOTS Email Converter on your Windows PC.
Click Open and select your PST file from the file picker.
Preview folders and emails in the left panel to confirm the data loaded correctly.
Click Save / Export and choose MBOX from the output format list.
Pick a destination folder and click Convert.
The MBOX output preserves your full folder hierarchy, all attachments and every message header. Output is compatible with Mozilla Thunderbird, Apple Mail, Postbox and any other MBOX-reading client. See our dedicated PST Converter page for advanced options.
What file formats can an email converter handle?
A complete email converter should handle three categories of source: file formats (PST, OST, MBOX, EML, MSG, OLM, OFT, DBX), desktop clients (Outlook, Thunderbird, Apple Mail, eM Client, Mailbird, Postbox, Mailspring, Windows Live Mail, Eudora) and mail servers and cloud services (Gmail, Office 365, Yahoo, iCloud, Zimbra, MDaemon, Kerio, Communigate, IMAP). For output, it should write to email files (PST, MBOX, EML, MSG), document formats (PDF, HTML, TXT, CSV, vCard, ICS) and direct cloud services. PCDOTS supports all of the above in a single tool.
How do I export email data in multiple formats?
Install PCDOTS Email Converter.
Upload your email files in the software interface.
Click Export and choose a saving format.
Browse to a destination path and click Save.
The emails are exported in the selected file extension.
Can I save emails to cloud-based email services?
Yes. The email converter writes directly to Gmail (using Google's IMAP protocol), Office 365, Yahoo, iCloud and any IMAP-compatible service. You will be prompted for credentials and the converter handles authentication, throttling and retries on its own.
Does the software allow you to print email messages?
Yes. Convert emails to Adobe PDF, then print from any PDF reader. PDF preserves formatting, headers and inline attachments cleanly, and the output is portable.
Can I extract phone numbers from email files?
Yes. The email converter has a dedicated phone number extraction feature that scans message bodies and signatures, then writes a deduplicated TXT list ready for import into a CRM or contact list.
How many emails can I export with the free version?
The freeware edition exports up to 10 emails per folder in the file format you choose. That is enough to verify accuracy and folder structure before paying for the full edition.
Can I install your software on Windows 10 or Windows 11?
Yes. The email converter for Windows runs on every release from XP and Vista through Windows 11, including all Server editions back to Server 2003. Both 32-bit and 64-bit builds are supported.
Can I convert raw email files using this email converter?
Yes. The tool reads raw RFC 2822 email files, MIME-encoded archives and orphaned mailbox formats, then converts them to any standard extension you select. This functionality is also marketed as the Raw Email Converter.
How long does email conversion take for a large mailbox?
Conversion speed depends on mailbox size and the output format you pick. For typical PST files, 10,000 emails convert in roughly 8 to 12 minutes on a standard PC with an SSD. The converter processes folders in parallel and shows real-time progress with an estimated time remaining. Larger mailboxes (100,000+ emails) typically finish inside 60 to 90 minutes.
Is my email data sent to your servers during conversion?
No. PCDOTS Email Converter processes all data locally on your computer. No emails, attachments or credentials are uploaded to our servers. The software is fully GDPR-compliant (see official GDPR regulation text) and suitable for handling sensitive corporate, legal or healthcare data. Network access is only used when you explicitly pick a cloud destination like Gmail or Office 365, and even then, the data goes directly from your PC to that service, never through us.
What is the difference between the trial and full version?
The free trial converts up to 10 emails per folder, lets you preview the entire mailbox structure and supports every output format. The full version ($49 lifetime license) removes the 10-email limit, enables batch processing of unlimited mailboxes, includes priority email support and ships lifetime updates. See the complete comparison table above for a feature-by-feature breakdown.
Can I run PCDOTS Email Converter on Mac or Linux?
PCDOTS Email Converter is a native Windows application. Mac and Linux users can run it through virtualization software like Parallels Desktop, VMware Fusion or the free VirtualBox running a Windows guest. We have tested the software on Windows 11 ARM virtualization on Apple Silicon Macs (M1, M2, M3) and confirmed full compatibility.
How do I convert encrypted or password-protected emails?
For password-protected PST and OST files (refer to Microsoft's official PST file documentation for format details), simply enter the password when prompted during file loading. For S/MIME or PGP-encrypted email content, decrypt the messages first in your client (Outlook, Thunderbird, etc.), then convert. The email converter preserves digital signatures and certificates in the output where the target format allows it. PDF/A and EML retain certificate data, while plain TXT and CSV exports strip cryptographic metadata.

"It saved our team three full days of manual work."
PCDOTS Email Converter is one of the most ideal products I have used in 12 years of IT consulting. When I needed a way to convert thousands of message files from a legacy email server into PST files for archiving, this tool ran the entire job in under two hours and kept the folder hierarchy exactly as it was on the source. The client confirmed every single email was readable.
