This section covers browser-based tools that change audio and video files: converting between formats, extracting audio from video, and turning speech into text. Every service listed here works in your browser, requires no account or payment card, and is free to use for the tasks described. You will find a ranked list of the most useful options, what each one does, and what the free version actually includes.

How to choose between them
If you need to convert an audio or video file to another format, start with EchoWave or VidShift. EchoWave has no file-size limit and no watermark; VidShift processes everything locally on your device. For turning audio into text, use Whisper Web if you want the transcription to stay entirely on your device, or VocaScript if you prefer a guest-accessible browser tool. HappyScribe and VEED are more limited alternatives: HappyScribe works for basic audio conversion and audio-to-video, and VEED offers a free audio-to-video converter plus a short free trial for transcription. None of these services are sources for downloading media from third-party sites; they convert or transcribe files you already have or upload yourself.
