Converting Ami Pro .SAM to RTF for Maximum Compatibility

Why RTF still matters in 2026

RTF looks like a relic and behaves like infrastructure. Microsoft published it in the late 1980s as a cross-application interchange format, and its reach is extraordinary: Word, WordPad, LibreOffice, Pages, Google Docs, Apple TextEdit, virtually every document management system, and a long tail of in-house applications written between 1995 and 2015 all read it.

That reach is the entire argument. DOCX is better in most technical respects, but DOCX support depends on a component being recent enough. RTF support depends on almost nothing. When you are handing documents to a system you did not build and cannot inspect, the format with the fewest requirements wins.

There is a second, quieter reason. RTF is plain text markup, not a ZIP archive of XML. You can open it in an editor, grep it, diff two versions, and script transformations on it with nothing but standard tools — which matters a lot during a large migration when you need to audit what happened.

When RTF beats DOCX

What survives an Ami Pro to RTF conversion

RTF is a formatted-text format, so the substance of an Ami Pro document comes across intact rather than being flattened. This is not a plain-text extraction with a different extension.

• Paragraph styles derived from the .STY style sheet, so headings remain visually distinct
• Tables as real table structures with cell borders and content preserved
• Character formatting — bold, italic, underline, superscript, subscript, and font changes
• Bulleted and numbered lists as list structures rather than typed characters
• Images: recovered WMF/EMF diagrams and rendered equations embedded directly in the file
• Text encoding normalised so accented characters from legacy code pages survive

The trade-offs to be aware of

RTF files are larger than DOCX for the same content, because DOCX compresses its XML and RTF does not. With embedded images the difference is noticeable — a document with several recovered diagrams can be several times the size of the equivalent DOCX. For an archive of thousands of files, check your storage budget before standardising on RTF everywhere.

RTF also lacks the modern collaboration features people now expect. There is no equivalent of Word’s comment threading or robust track-changes model, so if the document is heading into a review cycle, DOCX is the better target and RTF is the fallback.

Finally, RTF implementations vary. The format is old and widely implemented, which means widely implemented slightly differently. Complex nested tables are the usual place where two applications disagree. If your destination is a specific system, test one representative document there before running the batch.

A practical dual-output workflow

The most efficient approach is to stop choosing. Ami Pro Converter emits multiple formats in a single pass, so select RTF and DOCX together and let one run produce both. Conversion time barely changes because parsing the source is the expensive part, not writing the output.

Then route by destination rather than by preference: DOCX for internal editing and review, RTF for anything crossing an organisational boundary or entering an older system. Keep both in your output tree and the decision becomes a copy operation instead of a re-conversion.

If you also need a fixed record for retention, add PDF to the same run. Three outputs, one parse, no repeated work — and a single conversion log covering all of them.

Verifying RTF output

Test in the destination application, not in Word. Word opens almost anything; the point of RTF is compatibility with the system that will actually receive it, so that is where the test belongs.

Focus on the two areas where RTF implementations diverge. Open a document with a complex table and confirm columns and merged cells survived. Open a document with embedded diagrams and confirm the images render rather than appearing as blank frames or unresolved objects.

Also confirm character encoding with a deliberately awkward document — accented names, currency symbols, dashes. RTF encodes non-ASCII characters with escape sequences, and this is the one place where a sloppy conversion shows up as mojibake in a way that is easy to catch early and painful to catch late.
