What Is PST to HTML Conversion?
PST (Personal Storage Table) is Microsoft Outlook's format for storing email, calendar, contacts, and attachments in a single file. PST to HTML conversion turns that mailbox into HTML web pages you can open on any device. You get styled, readable output — no Outlook or email client needed.
HTML is the same format used for web pages. When you convert PST to HTML, each message is rendered with headers, body, and basic formatting inside one or more .html files. Double-click a file and it opens in Chrome, Firefox, Safari, or Edge. You can scroll through emails, use find/search, and archive or share the file easily.
Our free PST to HTML converter processes on your device. You drop a .pst file, keep HTML selected as the output format, and click Convert & Download. All processing happens on your device; nothing is uploaded. The result is a portable archive that works on any device — ideal for backup, sharing threads, or viewing mail when you don't have access to Outlook.
