Converting…
Sound Booster’s Audio Converter is a free browser tool that turns an audio file from one format into another — for example MP3 to WAV, M4A to MP3, or a video soundtrack into a clean audio export. Different apps and devices still disagree about which formats they open cleanly. A voice memo from a phone, a DAW bounce, or a clip from the web may need a different container before it plays, uploads, or imports the way you expect.
Instead of installing a desktop suite, you load the file here, choose the output type, convert, and download. Processing is designed to run on your device so everyday files do not need to sit on a remote server for this step. That makes the tool useful for quick compatibility fixes, preparing tracks for editors, sharing lighter files, or extracting sound from a video when you only need the audio.
Supported outputs include common choices such as MP3, WAV, AAC, M4A, OGG, FLAC, WEBM, and OPUS. What you can decode as input depends on your browser; Chrome and Edge usually cover the widest set of everyday files. For long or high-resolution masters, a shorter clip or a WAV intermediate is sometimes more reliable than a single heavy pass.
Many online converters send your track to a remote server first. Here the conversion is designed to stay on your device, so everyday files do not need to leave your computer for this step. That reduces friction when you are working with voice notes, podcast takes, or music demos you would rather not upload to an unknown host.
Typical web tools restrict uploads to a fixed megabyte limit. With a browser-based flow, practical size depends mainly on available memory on your device rather than a fixed server quota. Short clips finish quickly; larger projects may need more RAM, but you are not blocked by an arbitrary “max 50 MB” label on someone else’s form.
Switch between common formats such as MP3, WAV, AAC, M4A, OGG, FLAC, WEBM, and OPUS, or pull sound from a video file when you only need the audio. Pair conversion with Volume Booster, Trimmer, and other tools on Sound Booster so a file can move from format fix to loudness fix without leaving the site.
You can convert without creating a profile, and the page does not add a watermark to the file you download. Open the tool, choose a format, and save the result — useful when you only need one clean file for a deadline, a client drop, or a quick share.
Converting audio online with Sound Booster is a short, linear flow. You stay on this page until encoding finishes, then save the result to your device or to Your Library for later tools on the site.
Drag an audio file (or a video with a soundtrack) onto the upload area, use Choose a file, or open something already stored in Your Library. Keep the tab open while the browser reads the file.
Pick MP3, WAV, AAC, M4A, OGG, FLAC, WEBM, or OPUS based on where the file will go next — players, editors, courses, or sharing. The same format as your source is hidden so you always convert to something different.
Click Convert and wait for progress to finish in the browser. Download the new file, or save it to Your Library if you want to trim, boost, or edit it with other Sound Booster tools.
If a format fails to encode on your browser, try WAV first — it is the most predictable path — then convert that result to a compressed format if you still need a smaller file.
Output options include MP3, WAV, AAC, M4A, OGG, FLAC, WEBM, and OPUS. What you can decode as input depends on your browser (Chrome and Edge usually handle the widest set). Large files take more memory — if conversion fails, try a shorter clip or convert to WAV first.
No. Conversion is designed to run locally in the browser. Your file is not uploaded to Sound Booster servers for this step.
Lossless targets like WAV or FLAC keep the decoded samples. Compressed formats such as MP3 or AAC are lossy by design, so a small amount of detail can be discarded compared with a lossless master — that is a property of the format, not a separate “extra” reduction by the page. For music, podcasts, and voice, everyday results usually sound very close to the source.
Yes. You can convert without creating an account or paying for a plan on this page. Browser limits still apply for very large files and for codecs your browser cannot decode or encode.
No desktop installer is required for the core flow. The page runs in a modern browser. Some advanced formats use an in-browser encoder that may download once on first use, then run locally.
You can target MP3, WAV, AAC, M4A, OGG, FLAC, WEBM, and OPUS. Input support depends on what your browser can decode — MP3 and WAV are the most widely accepted starting points; many browsers also handle AAC/M4A and common video containers when you only need the audio track.
If the browser can decode the video’s audio stream, you can load the video file and export an audio format. Silent videos will not produce a useful audio file.
There is no account-based quota on this page. Practical limits come from your device memory, tab stability, and file size — very large or long files may need to be split or converted in a lighter format such as WAV in stages.
Some codecs are missing in certain browsers, and heavy files can run out of memory. Try Chrome or Edge, a smaller file, or WAV output first. Keep the tab in the foreground until encoding completes.
