Free online WMA to RTF converter

WMA files contain recorded audio, while RTF files contain formatted characters, so this task is a speech-transcription workflow rather than a direct format conversion. It is useful when a recording must be edited, searched, shared, or opened in a word processor that requires .rtf.

What the WMA format is

WMA (Windows Media Audio) is an audio format developed by Microsoft. It stores spoken recordings and music using the Windows Media Audio codec; some WMA files are lossy and others use Windows Media Audio Lossless. You may encounter it in recordings made with older Windows software, digital voice recorders, media libraries, and files exported by Windows Media Player or related applications.

A WMA file does not contain document characters or formatting. Its speech must be recognized by transcription software before an RTF document can be created.

What the RTF format is

RTF (Rich Text Format) is a text-document format supported by Microsoft Word, WordPad, LibreOffice Writer, and many other word processors. It can preserve basic formatting such as paragraphs, bold and italic text, headings, and simple document metadata without depending on a proprietary word-processing format.

RTF is appropriate when you need an editable transcript with broad desktop compatibility. It cannot preserve the original audio, speaker tone, background sound, or timing unless the transcription tool adds that information as text.

How to actually convert WMA to RTF

Use the built-in online converter

1. Open the WMA-to-RTF converter on 101convert.com; the service can be used for free without installing software.
2. Upload the .wma recording and choose RTF as the output format.
3. Start the conversion. Because RTF cannot store audio, the service must transcribe the spoken content with speech recognition before producing the document.
4. Download the resulting .rtf file and open it in Word, WordPad, or LibreOffice Writer.
5. Check names, numbers, punctuation, and speaker changes against the recording before distributing the transcript.

Use desktop tools

For a local workflow, first decode the WMA file to a speech-friendly WAV file with FFmpeg:

ffmpeg -i recording.wma -ar 16000 -ac 1 speech.wav

Transcribe speech.wav with a speech-recognition tool such as Whisper, then open the resulting plain-text transcript in LibreOffice Writer and choose File → Save As, select Rich Text Format (.rtf), and save it. This approach keeps the audio and transcript processing local, but it requires installing and configuring FFmpeg, a speech-recognition model, and a word processor.

Quality, compatibility, and limitations

• WMA compression can reduce recognition accuracy through codec artifacts, especially in quiet speech, telephone recordings, or files repeatedly re-encoded.
• Clear speech, a low noise level, and separate speakers generally produce better transcripts than music mixed with speech or overlapping conversation.
• Transcription accuracy depends on the recognition model, language selection, accents, specialist vocabulary, and recording quality; an RTF file does not guarantee an accurate transcript.
• Directly renaming .wma to .rtf does not work because the formats have different binary structures and contain different kinds of data.
• RTF has broad compatibility but limited layout features. Use DOCX or another specialized format if you need complex tables, advanced styling, embedded media, or precise time-coded transcripts.
