About This Tool

rqrcode generator converts a payload into a QR code image that can be scanned across devices. It supports input types such as text, URLs, vCards, and wifi payloads, with options for version auto or fixed, and adjustable size.
Conceptually, the tool encodes the payload into a QR matrix following standard specifications, placing finder patterns and timing modules, then renders a scalable SVG for crisp printing and web use.
Who benefits includes marketers, developers, event organizers, and product teams needing quick, portable data encoding and easy asset distribution. Use cases span website links, contact cards, wifi credentials, tickets, and coupons across print and digital media.
Unique value lies in deterministic vector output, robust input validation, and configurable error correction, producing a portable asset suitable for diverse workflows. Core features include payload-type support, versioning options, color and margin controls, and an SVG export that maintains sharpness at any size.

How to Use

Provide inputs: enter data_to_encode (text, URL, vCard, or wifi payload).
Choose method: select payload_type and error_correction level.
Set options: adjust size_px and margin_px; pick foreground/background colors.
Run generation: trigger the QR code rendering.
Retrieve outputs: copy the SVG, download PNG if available, and validate scannability.

Frequently Asked Questions

Find Quick Answers

What types of data can I encode?

The tool supports plain text, URLs, vCard contacts, and simple wifi credentials. For non-text payloads, data is encoded in byte mode using UTF-8 to maximize compatibility across scanners and devices.

How does error correction affect QR size?

Higher error correction (H) increases data overhead, which may raise required version or reduce payload length. Lower levels (L) allow more data but reduce resilience to damage or distortion in printing or scanning.

Is the SVG scalable and scannable?

The output is a scalable vector graphic that preserves sharpness at any size. Scannability depends on payload length, error correction level, and proper quiet zone; always test with multiple scanners after export.

What are data limits for versions?

QR versions define module count and capacity. Auto version adjusts to the payload and error correction setting; fixed versions constrain capacity. Exceeding capacity prompts version upgrade or a data truncation warning.
