Features
Built for One Thing. Done Right.
OpenMSG is purpose-built to open MSG files on Windows — fast and with zero bloat. Here's everything it can do.
DownloadFast File Opening
Millisecond load times, even for large MSG files
OpenMSG uses optimised native parsing to open MSG files instantly. No loading spinners, no progress bars — just immediate access to your email content, regardless of file size or complexity.

Complete Email Rendering
See every email exactly as it was sent
Full HTML email rendering with embedded images, formatting, and rich content. OpenMSG faithfully reproduces the original email layout so you never miss a detail.

Attachment Visibility
See every attachment at a glance
All attachments are clearly listed with file names, sizes, and types — so you always know exactly what was included in the original email.

Attachment Saving
Save individual attachments directly from the email
Any attachment inside an MSG file can be saved directly to your device. No need to forward the email or open Outlook — just open, find, and save.

Privacy & Security
Your MSG files are processed locally on your device
OpenMSG parses and renders MSG files on your machine. Email content is never uploaded to any server.
