Drop a video file onto the page or click Select Video. MP4, MOV, MKV, WebM and other formats are accepted.
Pick an output format - MP3, AAC, WAV, FLAC or OGG. Then select audio quality: Match Source attempts to copy the original audio without re-encoding when the output format is compatible with the source codec, or choose 320, 192 or 128 kbps for a specific bitrate.
Click Extract Audio. Processing runs entirely in your browser with no upload. When it finishes, download your audio file.
MP3 is the most widely compatible audio format and works on virtually every device and player - ideal for music, podcasts and general sharing. AAC offers better quality than MP3 at the same bitrate and is the default format on Apple devices. WAV is uncompressed and lossless, making it the best choice for professional editing where quality cannot be compromised, though files are much larger. FLAC provides lossless compression - the same quality as WAV in roughly half the file size - and is popular for archiving music collections. OGG (Vorbis) is an open-source format with quality comparable to AAC, commonly used in games and web applications.
Pulling the audio out of a video is one of the most common requests on the web, and the reasons go far beyond saving space. Podcasters routinely use a video to audio converter to turn recorded interviews, livestreams or Zoom calls into MP3 episodes ready for upload to Spotify, Apple Podcasts or a private RSS feed. Musicians and DJs extract audio from concert recordings, music videos and live sessions so they can listen on the move, sample sections in a DAW, or build a personal playlist that works in a car stereo that does not play video. Voice actors and content creators capture voiceover takes from screen recordings, then re-use the clean audio in a different edit without re-recording. Students and researchers strip audio from lectures, webinars and conference talks so they can listen at the gym, on a commute, or transcribe later with a speech-to-text tool. Language learners do the same with foreign-language films and YouTube downloads, dropping the audio onto an iPod or smart speaker for repeated listening. Anyone who values storage and battery life will also notice that an extracted MP3 is typically 5 to 20 times smaller than the original video, so a two-hour talk that fills 1.5 GB as MP4 fits in under 100 MB as audio.
The name is MP4 to MP3, but the converter is much broader than that. On the input side it accepts MP4, MOV, MKV, WebM, OGV, M4V, MPEG, MPG, MPEG-TS, AVI-style streams and the audio-only formats MP3, AAC, M4A, WAV, FLAC and OGG. That means you can drop in a screen recording from a Mac (.mov), a clip downloaded from a Telegram chat (.mp4), a Twitch VOD (.mkv or .ts), a phone recording (.mp4 or .m4v), a GoPro export, or even an existing audio file you simply want to re-encode into a different format. On the output side you can choose MP3, AAC, WAV, FLAC or OGG, so this single page covers MP4 to MP3, MP4 to WAV, MOV to MP3, MKV to FLAC, WebM to OGG and every other common pairing in one place.
Most online converters force a re-encode, which is slow and quietly degrades audio quality every time you process the file. VidShift takes a smarter approach. The default "Match source" mode performs a stream copy whenever the source audio codec is compatible with your chosen output container - the original encoded audio is repackaged byte-for-byte with no re-encoding, no quality loss, and processing that finishes in seconds even on long videos. If you do need a specific bitrate, the 320, 192 and 128 kbps presets give you predictable file sizes for music, podcasts or voice notes. WAV and FLAC outputs always preserve the full dynamic range, making them ideal when the audio is going into Audition, Logic, Audacity or Reaper for further editing.
If you need to extract audio from a folder of videos rather than a single clip, switch over to the dedicated batch video converter. It accepts the same set of input formats, queues every file with a single chosen output, and processes them sequentially in your browser with no upload step. This is the fastest way to convert a whole season of recorded meetings, a lecture series, or a music video collection into MP3 or AAC in one go - and because everything runs locally there are no per-file caps, no daily limits and no watermarks.
Almost every other "free MP4 to MP3 converter online" works the same way: you upload your video to a remote server, it processes the file, and you download the result. That model is convenient but it means a copy of your media now sits on someone else's hardware, often retained for hours or days, sometimes used to train models or surface ads, and almost always exposed to the operator's staff and any future security incident. VidShift is different. Conversion runs entirely inside your browser using WebAssembly and the WebCodecs API, so the bytes of your video never leave your device. There is no media upload, no server-side copy of your file, and no account to create or delete. That makes this tool safe for confidential interviews, internal meeting recordings, unreleased music, medical or legal recordings, and anything else you would not happily hand to a stranger. As a side effect, the conversion is also faster for large files because nothing has to upload, and the page even works offline once it has loaded once.
Drop or select your video file on this page. Choose your output format and quality, then click Extract Audio. The conversion runs entirely in your browser - no upload, no signup, no cost. When it finishes, click Download to save your audio file.
Yes. Despite the page name, this tool accepts all common video formats including MP4, MOV, MKV, WebM, OGV, and MPEG-TS. The audio track will be extracted regardless of the video container format.
It depends on your settings. If you select "Match source" and the source audio codec matches your chosen output format, the audio is copied directly with no quality loss. Otherwise, the audio is re-encoded at your chosen bitrate. Higher bitrates like 320 kbps preserve more detail.
This tool runs entirely in your web browser - no software installation needed. Open this page in Chrome or Edge, drop your video file, and click Extract Audio. The processing happens on your device using WebAssembly and WebCodecs technology.
MP3 is the most widely compatible compressed audio format - great for music and podcasts. AAC offers better quality at the same bitrate and is used by Apple devices. WAV is uncompressed lossless audio - perfect quality but much larger files. FLAC is compressed but lossless, offering a good balance of quality and size.
Speed depends on your device and file size. If the source audio matches your chosen format and you select "Match source" quality, the extraction is near-instant since no re-encoding is needed. Full transcodes typically process faster than real-time on modern devices.
There is no hard limit. The practical limit depends on your device's available memory. Since only the audio track is extracted, even large video files produce relatively small audio outputs. Most modern devices handle files up to several gigabytes without issues.
Yes. Your files never leave your device. VidShift has no backend servers that receive or store your media. All processing runs locally in your browser using WebAssembly, ensuring complete privacy. The tool even works offline after your first visit.
Yes - while this page is named MP4 to MP3, it works as a full audio extractor for any video format including MOV, MKV, WebM, AVI and more. Simply drop your video file and choose your preferred audio output format from the selector.
Absolutely. Use the format selector to choose WAV (lossless, large file), FLAC (lossless, compressed), AAC (smaller than MP3, great quality), or OGG. MP3 is selected by default as it is the most universally compatible.
AAC generally produces better audio quality than MP3 at the same file size, and is the default format on iPhones and Apple devices. MP3 is more universally supported across all devices and players. For most uses, either is fine - choose MP3 for maximum compatibility or AAC for slightly better quality.
It is a fully online video to audio converter that runs in your browser. There is nothing to install, no extension to add and no account to create. Open the page in Chrome, Edge, Firefox or Safari, drop a video, pick an output format and download the audio. Because the conversion happens locally rather than on a remote server, the page also continues to work offline after your first visit.
Yes. This page is optimised for converting one video at a time, but VidShift also has a dedicated batch converter that accepts a queue of files and extracts audio from every one of them with a single chosen output format. It is ideal for podcast back catalogues, recorded meetings or music video collections, and like this page it runs entirely in your browser with no uploads.
VidShift does not download videos from YouTube or any other streaming platform - it only works with files already saved on your device. If you have legitimate access to the source video (your own upload, a permitted download, a screen recording, or a clip licensed for reuse), drop the file here and the audio will be extracted locally in your browser.
Yes. The tool runs in any modern mobile or desktop browser that supports WebAssembly and WebCodecs, which includes recent versions of Chrome, Edge, Safari and Firefox on iOS, Android, macOS, Windows, Linux and ChromeOS. On phones, processing speed depends on the device, but extracting audio is far less demanding than transcoding video so even older handsets handle most files comfortably.
