Questions

Is the video uploaded?

No. The MP4 is read and converted by your browser, on your device. That is also why it works offline once the page has loaded.

Is it really free?

Yes. No account, no watermark and no limit on the number of files. Files up to 200 MB and 60 minutes work best; longer ones can run out of browser memory.

Which formats can I convert?

Anything your browser can play: MP3, M4A, AAC, WAV, OGG, OPUS, WEBM, FLAC, and the audio of MP4, MOV and WEBM videos. Chrome and Edge read the most formats.

Can I turn the recording into text?

Yes. Press "Transcribe this file" after converting and AllNote Transcribe turns the speech into text with speaker names, in 100+ languages. The first 5 minutes are free.
