Overview
Generic QR generators solve encoding but not presentation. This utility combines QR generation with controlled brand treatment and export, without requiring uploaded assets to leave the browser.
ChallengeCreate usable QR assets that still look intentional and on-brand.
SolutionCompose QR modules, color, sizing, and an optional center logo directly in browser canvas.
ResultA private, repeatable workflow that produces downloadable branded PNG files.

Engineering decision
Local image processing reduces privacy friction and keeps the tool deployable as a static page. The interface exposes the meaningful controls without turning a small production task into a design application.
What this project demonstrates
- Translating a brand requirement into a focused production utility.
- Handling local file input and canvas composition without transmitting customer assets.
- Balancing visual customization with QR readability and error correction.
- Delivering a useful export workflow in a lightweight static application.
