Free online RTF to OGG converter

An RTF document contains formatted text, not audio, so converting it to OGG means synthesizing its words as speech. This is useful when a player or device accepts audio files but cannot open the original document.

What the RTF format is

RTF (Rich Text Format) stores text and basic formatting such as fonts, boldface, and paragraph alignment. Word processors including Microsoft Word and LibreOffice Writer can create RTF files; they are also common as exported documents and email attachments.

What the OGG format is

OGG is a multimedia container commonly used for audio encoded with the lossy Vorbis codec. OGG Vorbis can provide smaller files than uncompressed audio, but support varies across devices and players. Here, the document’s readable text is turned into spoken audio and saved in an OGG file.

How to convert RTF to OGG

Online on 101convert.com

1. Open the RTF-to-OGG converter page and upload the RTF file. The page allows batch conversion and shows the per-file size limit.
2. Before converting, choose the voice language and reading speed.
3. Start the conversion, then download the resulting OGG file or files.

Offline with desktop software

LibreOffice, eSpeak NG, and FFmpeg provide a free, open-source workflow on Windows, macOS, and Linux. First use LibreOffice to extract the document text, then synthesize speech and encode it as OGG Vorbis. With input.rtf in the current folder, run:

1. libreoffice --headless --convert-to txt --outdir . input.rtf
2. espeak-ng -f input.txt -w speech.wav
3. ffmpeg -i speech.wav -c:a libvorbis -q:a 5 output.ogg

Install the three programs first; the commands assume their executables are available in the system path. The FFmpeg quality value 5 sets a moderate Vorbis quality level; a higher value generally increases audio quality and file size.

Balabolka is a Windows desktop option. Open the RTF file, choose a voice, then use File → Save audio file and select OGG as the output format if it is available in the format list. Available audio formats can depend on installed system components.

Quality and compatibility

Speech synthesis does not preserve page layout, images, or visual formatting; it reads the document’s text. Check the selected voice language and reading speed, especially for abbreviations or names. OGG Vorbis is lossy, and some hardware players do not support it; confirm the target device can play OGG before converting.
