Bulk QR Code Generator

Tool Description

Bulk QR Code Generator (BQ) is a two-column, color-calculator–styled utility that converts a list of URLs (pasted or from CSV) into downloadable QR codes. It supports size, error-correction level, and foreground/background color controls, generates individual PNGs, and bundles all codes into a ZIP. A built-in light/dark theme toggle persists your preference.

What it does
