Privacy Policy

We value your privacy. Understand how our tools work and how your data is protected.

Last updated: October 2026

1. In-Browser Processing & Zero File Uploads

MPEG to MP3 is engineered with a privacy-first architecture. All audio and video processing occurs locally in your web browser via WebAssembly technology.

  • No File Uploads: Your media files are never uploaded, transmitted, or saved to our servers or any third-party storage.
  • Memory Isolation: File reading, demuxing, audio track extraction, and MP3 encoding operate exclusively within your browser's local sandbox memory.
  • Instant Cleanup: As soon as you navigate away, refresh the page, or clear a file from the converter, the temporary memory allocation is immediately released by your browser.

2. Information We Collect

Because all file conversion takes place on your device, we do not collect personal media files or account information. We only handle the following minimal data:

  • Local Storage: We use your browser's local storage to save user preferences, such as your theme choice (Dark or Light mode) and audio quality options. This data stays entirely on your device.
  • Server Log Data: Like most websites, our web hosting servers automatically record standard connection logs, including IP address, browser type, operating system, referring URL, and access timestamps. This data is used solely for server security, performance monitoring, and DDOS protection.

3. Cookies and Advertising Disclosures

We use cookies and similar technologies to improve website functionality, analyze site performance, and deliver relevant advertisements.

  • Essential Cookies: Required for core site navigation, language selection, and theme settings.
  • Google AdSense & Third-Party Advertising: Third-party vendors, including Google, use cookies (such as the DoubleClick cookie) to serve ads based on your prior visits to this website and other websites on the internet.
  • Ad Personalization Opt-Out: You can opt out of personalized advertising by visiting Google Ads Settings or through the Digital Advertising Alliance (AboutAds.info).
  • Cookie Management: You can update your cookie preferences at any time using our on-site cookie banner or through your browser's privacy settings.

4. Analytics and Performance Metrics

We may use privacy-compliant web analytics to gather aggregated, non-personally identifiable metrics (such as page visit counts, device categories, and error rates). This information helps us optimize audio conversion performance and maintain cross-browser compatibility across Chrome, Safari, Firefox, and Edge.

5. External Links

Our website and educational articles may contain links to external third-party software, specifications, or tools (such as VLC, Audacity, and HandBrake). We do not control and are not responsible for the content or privacy practices of third-party websites.

6. Your Privacy Rights

Under data protection laws such as the General Data Protection Regulation (GDPR) and the California Consumer Privacy Act (CCPA), users have rights regarding their personal data, including the right to opt out of non-essential cookies. Because we do not store personal profiles, email databases, or uploaded files, no identifiable user media records exist on our servers.
