QR Code Tools Directory

Every free QR code tool on QR Studio, organised by category. From single-type generators to bulk CSV importers, industry suites, print calculators, safety checkers, and advanced optical engineering tools — all run in your browser with no sign-up required.

QR Code Generators

Create free QR codes for URLs, WiFi networks, contact cards, payments, events, and 30+ more data types. Every generator runs in the browser — no data leaves your device.

Bulk QR Generators

Generate hundreds of QR codes from a CSV file in a single batch. Download as a ZIP of PNGs or as a printable PDF sheet. Perfect for events, inventory, and team onboarding.

Industry QR Suites

Pre-configured QR tool bundles for specific industries. Each suite includes ready-to-print QR codes, payload templates, and best-practice guidance tailored to the business type.

Print & Size Tools

Calculate the minimum QR code size for any print medium — business cards, banners, packaging, billboards, and labels. Ensure every printed QR code is scannable at its intended distance.

Safety & Security Tools

Inspect, verify, and audit QR code payloads before scanning. Detect phishing URLs, typosquatting, redirect chains, and brand impersonation in QR codes from unknown sources.

Design & Output Tools

Customise, brand, and export QR codes in any format. Add logos, frames, gradients, and call-to-action text. Export to SVG, PNG, PDF, or ZIP bundles for print-ready production.

Analytics & Campaign Tools

Plan, measure, and optimise QR code campaigns. Estimate scan rates, model ROI, run A/B tests, and audit UTM parameters — all without sending data to third-party servers.

Technical & Advanced Tools

Advanced optical engineering tools for QR code analysis, error correction simulation, version estimation, and offline file transfer. Ideal for developers and print engineers.

Business, ID Cards & Store Tools

Free document and design tools for businesses, schools and shops: invoices, quotes, receipts, ID cards, certificates, price tags, sale posters and print-ready photos. Everything runs in your browser — your data never leaves your device.
