Reverse Audio Online — Free, Private, No Upload
Runs entirely in your browser. Your audio never leaves your device.
This free tool reverses audio directly in your browser. Press record or drop an MP3, WAV, M4A, OGG, or WebM file, press Reverse, and hear the result backwards in about a second. Processing runs on your device with the Web Audio API — no upload, no account, no watermark. Download the reversed clip as a WAV, free.

Look for the mic prompt near your address bar. Nothing records until you allow it.
Decoding on your device — nothing is uploaded.
Your browser is blocking the mic for this site. Re-enable microphone access in site settings, then reload.
The Web Audio API isn't available here, so in-browser reversing won't work. The Reverse Audio PRO app reverses without limits — see how to reverse audio on iPhone or on Android.
How do I reverse audio online?
Three steps, no software to install. The whole flip happens inside your browser tab, so it works the same on a laptop, a phone, or a locked-down work machine.
- 01 Record with the mic button, or drop any MP3, WAV, M4A, OGG, or WebM file onto the card above.
- 02 Tap Reverse. The flip happens on your device in under a second — nothing is uploaded.
- 03 A/B between original and reversed, then download the result as a WAV — free, no sign-up.
How does this free tool compare to the app?
The browser tool is a complete reverser: record, load a file, flip it, compare, download — private and free. The Reverse Audio PRO app is the full studio around it: speed, pitch, ten effects, longer recordings, and more export formats.

Questions about the free audio reverser
Is my audio uploaded anywhere?
No. The tool decodes and reverses audio with the Web Audio API inside your browser tab. No file leaves your device, no server receives a byte, and nothing is stored after you close the page. You can load the page, go offline, and reversing still works.
What file formats can I reverse?
MP3, WAV, M4A, OGG, and WebM, up to 10 minutes or 25 MB. Drop an .mp4 video and the tool tries to pull the audio track out before giving up. For anything else, export the audio as MP3 or WAV first, then drop it again.
Is there a length limit?
Yes. Browser recordings cap at 5 minutes and files at 10 minutes or 25 MB, because everything is held in your tab's memory. The Reverse Audio PRO app records and loads full-length audio with no cap on iPhone and Android.
Is the tool really free?
Yes. Recording, reversing, A/B playback, and WAV download are free — no sign-up, no watermark, no usage limit. It is a working sample of the Reverse Audio PRO app, which adds speed, pitch, ten effects, and MP3/M4A export, with a one-time $4.99 Pro unlock.
Can I use my reversed recordings commercially?
Yes, if you own the rights to the source audio. The tool adds no license of its own — your recording stays yours. Reversing copyrighted music you do not own does not create a new right to use it, so clear samples the same way you normally would.
