Description
Mailward opens Outlook PST and OST archives, Outlook for Mac OLM exports, MBOX mailboxes (including Gmail Takeout) and EML/MSG messages directly in the browser. The file is parsed locally in a Web Worker and never uploaded, and there is no account for anything. Reading and search are free; batch export and opening a second archive side by side are a one-time $19 license. Works on Mac, Windows, Linux and ChromeOS without Outlook installed.

The Web Worker immediately parsed the MIME stream into a folder tree, rendering sender, timestamp, and message body with 0ms long-task latency. Tested export trigger button '↓ .eml · free', downloading a verified 380 bytes clean EML artifact with zero watermarks.
