🧠 AzPix Pro – Turn Any File into a Rainbow PNG

💡 Inspiration

AzPix Pro was inspired by the concept of steganography and the growing need for creative, secure file storage. I wanted to build a tool that could disguise any file or folder as a beautiful, innocent-looking image — while keeping the original data safe and retrievable.

It’s not just about hiding data — it’s about transforming it into something visually appealing and technically protected.

🔨 How I Built It

• The application was developed in C# using Windows Forms (.NET Framework)
• File and folder inputs are compressed using the LZMA (7-Zip SDK) algorithm
• The binary data is embedded into a visually generated PNG using the System.Drawing library
• Rainbow-colored patterns are dynamically generated for each file
• The app has a simple, user-friendly interface fully localized in Uzbek

🧠 What I Learned

• Deep understanding of PNG file structure and data chunking
• Working with streams, memory buffers, and binary data
• Fine-tuning compression with LZMA for performance vs. size
• Designing UI/UX in a multilingual, non-English environment
• Implementing data recovery from non-standard file containers

🚧 Challenges Faced

• Ensuring that generated PNGs are viewable and not corrupted after embedding large files
• Handling multi-file input and recursive folders efficiently
• Avoiding false positives from antivirus programs due to archive-like behavior
• Maintaining data integrity even after sharing via messengers or social media

Despite these hurdles, AzPix Pro now reliably turns files into colorful art — and back again.
