extract audio from screen recording
Screen recordings — tutorials, demo walkthroughs, narrated presentations — are saved as video by default, but the narration itself is often the part worth keeping separately: for transcription, for reuse in another project, or just to free up space once the video's visual content is no longer needed.

Screen recording tools save output in a range of formats depending on the software and platform — MP4 and WEBM are common from browser-based and OS-native recorders, MKV and MOV show up from various desktop tools. This extractor accepts all of these through the same upload box, so the specific recorder you used doesn't matter.
The narration audio is preserved at LAME VBR quality level 2 (roughly 190kbps), which is more than sufficient for spoken narration — voice content doesn't need anywhere near the bitrate that music does to sound clear, so this setting comfortably keeps speech intelligible and natural.
A common next step after extraction is transcription — turning narration into text for captions, show notes, or a written tutorial. If that's your goal, ToolerWork's Speech to Text tool can take the extracted MP3 and produce a transcript, keeping the whole workflow browser-based and free.
Keep in mind this only extracts what was already recorded — if your screen recording has no audio track (a silent screen capture with narration added separately, for instance), there's nothing to extract, and the output will be empty or silent. This tool works with recordings that already have a narration or system-audio track baked in.

FAQ
Does this work with any screen recording software's output?
Yes, it accepts common formats like MP4, WEBM, MKV, and MOV, which cover most browser-based, OS-native, and third-party screen recorders.
What can I do with the extracted narration audio?
Use it for transcription, reuse in another project, or simply keep the audio and discard the larger video file once you no longer need the visual content.
Can this transcribe the narration into text?
Not directly, but ToolerWork's Speech to Text tool can take the extracted MP3 and generate a transcript as a separate step.
What if my screen recording has no audio track?
There's nothing to extract in that case — this tool pulls out whatever audio track already exists in the file, it doesn't generate narration.
Is my screen recording uploaded to a server?
No. Extraction runs entirely in your browser using FFmpeg WebAssembly, which matters if the recording contains sensitive on-screen content.
