Know Exactly Who Leaked
Your Unreleased Music
Embed invisible watermarks into your tracks before sharing. If a song leaks, instantly identify which copy was shared and who received it.
Sharing Unreleased Music Is a Gamble
You send a demo to a label. Share stems with a collaborator. Give a journalist an early listen. Then your unreleased track appears on a leak site or gets posted to social media. Who shared it? Without proof, you'll never know.
How LeakGuard Protects Your Music
Three simple steps to trace any leak back to its source
Upload Your Track
Drop your WAV file into LeakGuard. Processing happens entirely in your browser — your music is never uploaded anywhere.
Create Unique Copies
Enter a name or ID for each recipient. Download a uniquely watermarked version for "Alex", "Jordan", "Label A&R", etc.
Trace Any Leak
If your track leaks, upload the leaked file. LeakGuard extracts the watermark and tells you exactly which copy was shared.
Built for Real-World Music Distribution

Inaudible Watermarks
Your music sounds exactly the same. The watermark is embedded in frequencies human ears cannot detect.

Frequently Asked Questions
Will the watermark affect my audio quality?
No. The watermark is embedded in frequencies and patterns that are imperceptible to human hearing. Your music will sound identical to the original. We use spread-spectrum technology that distributes the watermark across the audio, making it both inaudible and resilient.
What audio formats are supported?
LeakGuard works with WAV files. For best results, watermark your high-quality master and then convert to other formats (MP3, AAC, etc.) for distribution. The watermark survives these conversions.
What can remove the watermark?
Casual sharing and format conversion won't remove it. Only extreme processing like significant pitch shifting, time stretching, re-recording through speakers/analog gear, or uploading to streaming platforms (YouTube, SoundCloud, Spotify) will destroy the watermark.
Is this DRM or copy protection?
No. LeakGuard is a forensic watermarking tool for leak tracing, not copy protection. It doesn't prevent anyone from playing or copying your files. It simply lets you identify the source if a leak occurs.
Do you store my files or watermarks?
No. Everything happens locally in your browser. Your audio files are never uploaded to any server. We have no way to access your music or watermark data. Your privacy is absolute.
