Meet Felix Zhu: Building a Privacy-First Digital Product Matrix

If you've ever worried about uploading your personal documents to a cloud server just to compress a PDF, or if you've spent hours looking for free, safe browser games without intrusive ads — Felix Zhu is the creator building exactly what you need.

Felix is an independent digital creator who operates a unique product matrix — a family of websites and publications designed around one core philosophy: your data should stay on your device, and useful tools should be free.

PrivacyPDF.org — Free, 100% Local PDF Compression

The flagship product. PrivacyPDF.org compresses your PDF files directly in your browser using WebAssembly — no uploads, no servers, no tracking. Your documents never leave your device.

• Three compression modes: Light, Balanced, and Extreme
• Batch processing: compress up to 3 files simultaneously
• Works on any device — desktop, tablet, or phone
• Supports files up to 100MB
• GDPR & HIPAA friendly by design (zero data collection)

For users who need unlimited batch processing and advanced compression, PrivacyPDF Pro offers a $4.99/month plan — still 100% local, zero data upload.

Bite-Arcade.com — 483 Free Browser Games

Bite-Arcade.com hosts 483 free browser games — no downloads, no installations, no account required. Just click and play. Categories include action, puzzle, racing, sports, and more. Perfect for a quick break during your workday.

What makes Bite-Arcade different? Zero intrusive advertising and a privacy-first approach — the same philosophy that powers PrivacyPDF.

Tiny-Arcade.com — Retro Pixel Gaming Nostalgia

Tiny-Arcade.com is the retro companion — 257+ classic pixel-style games that bring back the 8-bit and 16-bit era. Whether you grew up with arcade cabinets or just love that vintage aesthetic, Tiny-Arcade delivers authentic retro gaming directly in your browser.

KDP Books on Amazon — Practical Guides for Real Life

Felix is also a published author on Amazon Kindle. His books follow the same practical, no-fluff philosophy:

• The Practical AI Guide for Seniors — A jargon-free introduction to AI tools for older adults who want to stay connected and independent.
• The Teen Money Playbook — Financial literacy for teens: budgeting, saving, and understanding money before adulthood hits.
• The Practical Digital Detox Playbook — Step-by-step strategies to break screen addiction and reclaim focus — without going off the grid.
• The Practical Decluttering Playbook — A systematic approach to clearing your space and your mind.
• Chair Yoga for Seniors Over 60 — 10-minute seated routines to relieve stiffness, improve balance, and prevent falls.
• The 2-Hour Meal Prep System — A beginner's guide to planning, cooking, and storing a full week of healthy meals.

All books are available on Amazon Kindle and enrolled in Kindle Unlimited (KU), so KU subscribers can read them for free.

Why This Product Matrix Matters

Most online tools either upload your data to unknown servers or bombard you with ads. Felix's approach is different:

• Privacy by architecture — PrivacyPDF processes everything locally using WebAssembly. No server ever sees your file.
• Free access — Every tool and game is free to use. Pro upgrades exist but never restrict core functionality.
• Zero maintenance burden — Built once, works forever. Browser games don't need updates. PDF compression runs on client-side code.
• Cross-promotion synergy — Each site naturally introduces users to the others. Someone compressing a PDF discovers free games. A gamer finds a practical book on Amazon.
