About This Tool

The tool accepts multiple data types and encodes them into QR codes that conform to the ISO/IEC 18004 standard. It supports URL, text, wifi credentials, contact data, calendar events, and email/phone payloads. Conceptually, the system maps the input to a suitable encoding mode, selects an appropriate QR version, applies error correction, and renders a scannable symbol. Beneficiaries include product teams needing labeling, marketers generating campaign codes, and developers automating code generation in deployment pipelines. Unique value lies in offline generation, strict validation, and a clean SVG export that integrates with documents and apps without external dependencies. Core features include data_type selection, size and margin configuration, error-correction level, and a deterministic SVG output suitable for printing and digital use. Typical use cases include adding a URL to packaging, embedding contact details in a flyer, or provisioning Wi‑Fi access via a scanned code.

How to Use

Frequently Asked Questions

Find Quick Answers

What data types are supported?
Supported data types include url, text, wifi, vcard (contact), mailto, phone, sms, calendar, and simple data payloads. Each type follows its encoding rules to maximize capacity within the chosen size and error correction level.
Can I export SVG and ensure portability?
Yes. The tool outputs a standards-compliant SVG that scales without loss of detail. SVG export ensures crisp rendering on print media and screens, with no embedded fonts or external assets.
How should I choose size and error correction?
Larger sizes accommodate more data or higher error correction. If data length is near capacity, increase size_px or lower the error correction level to M. Higher error correction improves scannability on damaged surfaces.
Does the tool generate real, scannable codes?
Yes. The encoding follows QR Code standards with appropriate versioning, masking, and error correction. The resulting SVG represents a valid QR symbol that scanners can read when data fits the chosen configuration.
