Convert an Outlook .ost file to RTF by extracting each message’s body with its original formatting. The tool creates a separate bare RTF file for every message and bundles all files into a single downloadable zip archive. ⚠️ The conversion covers only message bodies; headers and attachments are not included.

Body‑only RTF extraction

The converter scans the uploaded Outlook .ost file, finds each stored message, and creates a separate RTF document for it. Every RTF file contains only the message body but keeps all original rich‑text styling—bold, italic, underline, font families, sizes, and paragraph layout—so the visual appearance of the email text stays the same.

Headers and attachments omitted

During conversion the tool intentionally leaves out all message metadata (From, To, Cc, Subject, Date) and any attached files. This produces lightweight RTF files that focus on readable content while preserving full text formatting. If you need headers or attachments, another export option on the site retains those elements.

Multiple messages bundled as ZIP

When the source .ost archive holds several emails, the converter generates an individual RTF file for each message and then automatically packages all files into a single ZIP archive. This bundled download lets you retrieve the entire converted set in one step, avoiding the need to handle each file separately.

Limits and scope

One .ost file per upload: Upload a single Outlook .ost archive per conversion; all messages inside are extracted together.
24‑hour retention: Source files and the resulting ZIP are stored for 24 hours before automatic deletion.
