RTF to MSG

Convert an RTF document to a native Outlook .msg file, preserving the exact rich‑text body, formatting and any inline images. The output is a ready‑to‑edit Outlook message where you can add recipients and a subject before sending. Works for single or multiple RTF files; when multiple files are uploaded, the resulting MSG files are packaged together in a zip archive.

Exact rich‑text formatting retained

The converter embeds the original .rtf body directly into the Outlook message as the rich‑text body, preserving bold, italic, underline, font families, sizes, colours, paragraph alignment, and list structures. No re‑flow or normalization occurs, so the layout you designed appears exactly the same when the .msg file is opened in Outlook, giving a faithful visual copy of the source document.

Because the .rtf file is taken verbatim, any complex layout you created – such as nested tables, multicolumn sections, or custom indents – is reproduced unchanged in the Outlook message. This ensures that the visual hierarchy and design intent remain intact, making the converted .msg ready for review or further editing without losing any formatting details.

Inline images stay inline

Images stored inside the .rtf travel with the message body as inline graphics, keeping logos, diagrams, or photos exactly where you placed them in the original document. The converter does not extract them as separate attachments, so the visual flow of text and pictures remains consistent within the Outlook message.

If you later need those graphics as separate attachment files, you can add them manually after opening the converted .msg in Outlook. This approach covers the common scenario of a formatted note or report that relies on embedded visuals, while still allowing you to detach images later if required.

Unicode support for all scripts

The generated .msg file is saved in Unicode, which means accented characters, Cyrillic, Chinese, Arabic, and other non‑Latin scripts are preserved exactly as they appear in the source .rtf. This ensures that multilingual documents remain readable, searchable, and display correctly in Outlook without character corruption.

Unicode storage also guarantees that special symbols such as mathematical operators, currency signs, or emoji survive the conversion unchanged. As a result, documents created in any language or script retain their full textual fidelity when transformed into an Outlook message, supporting global collaboration workflows.

One Outlook message per source file

Each uploaded .rtf produces a single native Outlook .msg file. When multiple .rtf files are submitted together, the tool bundles the corresponding .msg files into one zip archive, providing a convenient single download while keeping each source document isolated in its own message file.

The output messages contain only the formatted body – no sender, recipients, or subject – so you can add those details in Outlook before sending. This design creates a clean, ready‑to‑edit message for each document, streamlining the transition from a written draft to an email-ready format.

Limits and scope

File size

Supports RTF files up to the size limit of your Aspose account tier; larger documents require a higher‑tier subscription.

Batch size

Converts multiple RTF files in one request and returns a single ZIP archive; the number of files is limited by the overall upload size limit.

Retention

Source files and generated MSG files are kept on the server for 24 hours after conversion.
