Free QR code tools
Small, focused utilities we needed while building Qreator. Each one runs entirely in your browser — no signup, no upload, no watermark.
QR code reader
Upload a QR image or use your webcam to see exactly what a code contains before you trust it.
Bulk QR code generator
Paste or upload a CSV and download a ZIP of print-ready PNG or SVG files, one per row.
UTM builder + QR
Build a correctly tagged campaign URL and get the matching QR code in the same step.
Google review QR code
Turn your Place ID into the direct write-a-review link, with a QR code and policy-safe sign wording.
Scannability checker
Test colours, logo size and error correction against print reality before you commit to a run.
WhatsApp QR code
Build a click-to-chat code with a pre-filled first message, so you know which sign the contact came from.
QR code size calculator
Enter the reading distance and your link: get the printed width in millimetres that actually scans.
