Stop opening emails one at a time and printing to PDF. Mail Attachment Downloader PRO bulk-converts .eml and .msg emails and their attachments into PDF, merges each email with its attachments into a single document, and archives everything unattended — no Outlook, no manual clicking, no per-email limits.
Every email, plus every Word, Excel, or image attachment that came with it, folded into a single, searchable PDF — automatically, in bulk.
Works directly against IMAP, POP3, Gmail, Outlook.com, Yahoo, and Exchange — independent of any installed email client, and just as capable running on a server.
Instead of scattered files, produce a single document where the email is the cover pages and every attachment follows as rendered PDF pages.
PDF is the default target, but PRO Server opens up conversions across dozens of document, spreadsheet, presentation, and image formats.
Once emails are in PDF, PRO gives you real document-management power over them.
Configure a rule in the wizard, test it, and let it run — no scripting required.
IMAP, POP3, Gmail, Outlook, or Exchange — client-independent
Pick the From type and the To type — PDF, TIFF, DOCX, or 50+ others
Combine the email and its attachments into one PDF, oldest to newest
As a Windows Service, 24/7, in the cloud or on‑prem
Most tools convert one email at a time, or lock you into a single mail provider. PRO does bulk, unattended, multi-format conversion out of the box.
