SimpleCompressor

Privacy Policy

Last updated: January 2025

The Short Version

SimpleCompressor is built on a privacy-by-design principle. We never see, receive, store, or process your files. All compression and conversion happens entirely within your web browser using WebAssembly technology. Your files never leave your device.

What We Do NOT Collect

  • Your files (images, videos, audio, PDFs, documents)
  • File names or metadata
  • Compressed output files
  • Personal health, financial, or legal information contained in your files

What We May Collect

We may collect minimal, anonymized data to improve the service:

  • Page views and tool usage (anonymized, no personal identifiers)
  • Browser type and operating system (for compatibility)
  • Country-level location (no IP addresses stored)
  • Error reports (to fix bugs)

How Your Files Are Processed

When you use any compression tool on SimpleCompressor, the following happens exclusively in your browser:

  1. Your file is read into browser memory using the File API
  2. A WebAssembly module (FFmpeg, Canvas API, or JSZip) processes the file
  3. The compressed result is returned as a Blob in browser memory
  4. You download the result directly from browser memory to your disk

At no point is any network request made with your file data.

Cookies

We use no advertising cookies, tracking pixels, or fingerprinting. We may use a minimal session cookie for preferences (dark mode, etc.) that contains no personal information.

Third-Party Services

Our site may use the following third-party services, none of which receive your files:

  • Vercel (hosting) — serves the website, does not process files
  • Google Fonts — self-hosted via Next.js (no Google requests at runtime)
  • unpkg.com — CDN for FFmpeg WebAssembly binary (no file data transmitted)

Children's Privacy

SimpleCompressor does not knowingly collect any information from children under 13 years of age.
