Email & Calendar Tools

Free browser-based tools to open, analyse and extract from EML, MSG, MBOX, PST, ICS calendar and vCard contact files — your mail never leaves your computer.

Email File Viewer

Open EML and Outlook MSG files in your browser — headers, rendered body, MIME structure and attachments, with no mail client installed.

Email Archive Viewer

Browse an MBOX archive in your browser: search the message list, read any message and save it, without importing anything.

Email Header Analyzer

Decode an email's Received chain, delivery delays and SPF, DKIM and DMARC results — pasted or from a file, entirely in your browser.

Email Attachment Extractor

Pull every attachment out of EML, MBOX and Outlook MSG files at once and save them as a ZIP.

MBOX to EML Extractor

Split an MBOX archive into individual EML files, named the way you want, and download them as a ZIP.

EML to PDF Batch Converter

Turn saved emails into archival PDFs — one per message or one merged file, with real selectable text.

PST / OST Inspector

Open an Outlook PST or OST archive and see its folder tree, message index and file header — in your browser.

Email Thread Reconstructor

Group exported EML, MSG and MBOX messages into conversation threads using References and In-Reply-To.

ICS Calendar Inspector

Open an .ics file and inspect its events, recurrence rules, time zones, alarms and attendees.

Recurring Event Expander

Expand an iCalendar RRULE into the dates it actually produces, with EXDATE, RDATE and time zones honoured.

VCF Contact Viewer

Open a vCard file and read every field in it, photos included, without importing it into an address book.

VCF Contact Merger

Merge several vCard files into one, with scored duplicate detection you control and resolve card by card.
