Free online voice recorder

The audio file is an MP3, which plays on almost any phone or computer. The page makes it from your recording as soon as you stop. The file the browser recorded is there too: WebM in most browsers, M4A in some older versions of Safari. Recordings over 15 minutes come only in that format. File names carry the date and time, so a week of recordings sorts itself.

The text is a raw transcript of what the browser heard, written down as you speak. Expect little punctuation, no paragraphs and the odd misheard word, especially names. It is good for notes and for finding a moment in the recording. It is not finished writing. Copy it, or download it as a text file.

Download before you close the tab. The recording lives only in this page. Reloading or closing it deletes the recording, and the browser warns you if you try while recording.

The recorder uses MediaRecorder, the recording feature built into current browsers. The audio is held in the memory of this tab and is never sent to AudioPen or anywhere else. The MP3 is made in the same tab with LAME, a free MP3 encoder, and the downloads come from that same copy.

The live text uses the browser's own speech recognition, called the Web Speech API. In Chrome, the browser sends your audio to Google's speech service to turn it into text. Safari uses Apple's speech recognition. Firefox does not offer the feature, so there you get the recording without live text. Either way, AudioPen never receives the audio or the text.

Two limits follow from that. The live text works only while you record, so it cannot transcribe a file you already have. And its accuracy is the browser's, which is best with one clear voice close to the microphone. Browser support was checked on MDN and Can I Use on October 2, 2026.
