I built FileMock to solve a common testing problem - needing specific file types and sizes for QA work. It generates video, audio, PDF, and image files with precise size control, all running client-side in your browser.
Key features:
- No server uploads (everything stays local)
- Generated files are fully functional (videos play, PDFs have text, etc.)
- Instant generation for fast dev cycles
- Multiple formats supported
- Completely free
Perfect for CI/CD pipelines, QA testing, and development workflows where you need reliable test data quickly.
Built this after getting frustrated with downloading random files or creating empty placeholders that don't behave like real files.

Would love feedback from the HN community!
