MP4 to MP3

Converter App allows you to strip audio from videos completely free of charge. There are no hidden fees, no paywalls, and no account registration required. You can convert as many files as you like, regardless of whether it is a short clip or a long movie, with no limits on daily usage.

Extracting audio usually requires complex video editing software. Our tool simplifies this by working directly in your browser. No installation, ffmpeg codecs, or obscure plugins are needed. Your files are processed securely in the cloud, allowing you to download a ready-to-use MP3 in seconds on any smartphone, tablet, or computer.

We strictly adhere to a "Process & Purge" policy. Your files are transferred via enterprise-grade SSL encryption and processed in secure isolation. We do not view, copy, or mine your content. Once the audio extraction is complete, an automated system permanently deletes your files from our servers after 2 hours.

MP4 is the standard for watching, but it is inefficient for listening. Video files drain your battery by forcing screen playback and waste massive amounts of storage. Converting to MP3 liberates the audio track, reducing file size by roughly 90%. This makes your content perfect for background listening on smartphones, car stereos, and workout playlists where video isn't needed.

We don't just rename the file extension. Our engine technically detects and decodes the AAC audio stream typically found inside MP4 containers. It then re-encodes the signal using the industry-standard LAME MP3 encoder. This process ensures high fidelity and gives you full control: choose 320kbps for rich music quality or lower bitrates to save space for voice memos.

Video files are heavy, often exceeding the 100MB limits of standard online converters. Converter App is engineered for heavy lifting. We support uploads larger than 1GB, making us the ideal tool for extracting audio from full-length movies, long concerts, or webinar recordings. Our server-side stream processing ensures the audio is extracted efficiently without browser timeouts.
