Free online WEBM to TXT converter

Source format: WebM

WebM is a modern video container format designed for web delivery. It is commonly used by browsers, streaming platforms, screen recorders, and video-sharing tools because it supports efficient compression with codecs such as VP8, VP9, and AV1, often with Opus or Vorbis audio. A WebM file usually contains audio and video, so it is not a text document and cannot be converted to TXT in a literal format-preserving way.

Target format: TXT

TXT is a plain text format that stores only readable characters, with no video, audio, styling, or layout. It is widely used for notes, logs, subtitles, transcripts, captions, and extracted speech text. The main advantage of TXT is its simplicity and compatibility: almost every device and editor can open it. For a WebM file, converting to TXT usually means extracting text from the media, such as subtitles, captions, metadata, or a speech transcript.

How to perform the conversion

The best method depends on what kind of text you want from the WebM file:

1. If the WebM already contains subtitles or captions, extract them with a media tool such as FFmpeg. First inspect the streams with ffprobe input.webm. If a subtitle stream exists, you can extract it with a command such as ffmpeg -i input.webm -map 0:s:0 subtitles.srt. Then open the subtitle file in a text editor and save or convert it to .txt if needed.
2. If you need a transcript of spoken audio, use speech-to-text software. A practical desktop option is Whisper or another transcription tool that accepts video files. Typical workflow: open the WebM in the transcription app, run speech recognition, then export the result as .txt. Many tools also let you copy the transcript directly into a plain text editor.
3. If you only need metadata, use ffprobe or a media inspector to dump technical details into a text file. For example, ffprobe -v quiet -show_format -show_streams input.webm > info.txt creates a TXT report containing codec, duration, bitrate, and stream information.
4. If you want to do it online, you can convert the file on 101convert.com for free without installing any software.

For manual cleanup, open the resulting text in a plain text editor such as Notepad, TextEdit in plain-text mode, or VS Code, then save it as .txt.

Notes on quality and limitations

WebM to TXT is not a direct media conversion like changing one video codec to another. The result depends on what text can be extracted from the file. If the WebM has no subtitles, captions, or speech, there may be nothing meaningful to convert into TXT. Speech recognition can introduce errors, especially with background noise, accents, multiple speakers, or low-quality audio. Subtitle extraction is usually more accurate than transcription, but it only works when subtitle tracks are actually present. Also, TXT cannot preserve timing, styling, or speaker labels unless those are written into the text manually.
