⚙️ ISO/IEC 18004 2D Matrix Encoding & Reed-Solomon Error Correction
Quick Response (QR) codes encode up to 4,296 alphanumeric characters across a two-dimensional grid equipped with three corner Finder Patterns, alternating Timing Strips, and perspective Alignment Markers.
Unlike predatory 'free' QR websites that trap your links behind expiring redirect URLs, DH Tools encodes your payload directly into the static ISO/IEC 18004 bitstream using Reed-Solomon polynomial error correction—delivering permanent, zero-latency codes in PNG and vector SVG.
