FAQ

How much does it slow the song by default?
To 0.85×. You can make it slower or faster, and set the amount of reverb separately.
Is my song uploaded to your server?
No. Slowing and reverb both run in your browser; the file never leaves your device.
Can I post the result on TikTok or YouTube?
The tool only processes a file you provide; it doesn’t download songs or handle copyright. Make sure you have the rights to use the song before posting — each platform’s rules apply.
Is it free? Do I need an account?
Free, no account, no usage limits, and no watermark on the export.
