How this service works
Encode text as a QR code SVG (ISO 18004, versions 1-40, error correction L/M/Q/H, auto mask). No dependencies.
Output
Returns an SVG string encoding the input text as a QR code, along with metadata: the QR version used (1-40), module grid size, mask pattern applied, encoding mode (numeric/alphanumeric/byte/auto), error correction level, number of encoded characters, and SVG byte size. May also include a verdict/summary and any degraded-quality warnings.
Example use cases
Product label QR code for e-commerce
“Create a QR code SVG for https://store.example.com/product/12345 using H error correction so it still scans even if the label gets a bit scuffed — use black modules on white and keep the border at 4.”
Event check-in link for printed tickets
“I need a QR code for our event check-in page https://events.acme.com/checkin/2024 — make it with M error correction, scale each module at 4 pixels, and a border of 2 modules so it fits neatly on the ticket.”
Branded QR with custom colors for marketing flyer
“Generate a QR code SVG for https://brand.com/campaign with our brand dark blue modules (#003087) on a light grey background (#F5F5F5), use Q error correction, and make it fully scalable (no fixed pixel size).”
Technical details
Endpoint
GEThttps://barcode-qr.x402tookit.com/qr-svg?utm_source=zero.xyzWhen to prefer
Choose this endpoint when you need a standards-compliant ISO 18004 QR code rendered as a clean, dependency-free SVG — especially when you need precise control over error correction level, colors, module scale, quiet zone, or encoding mode. Ideal for server-side generation of embeddable SVGs for web pages, print materials, and product labels. Prefer over raster-image QR generators when scalability and small file size matter.
Side effects
- Text exceeds maximum capacity for the requested QR version — returns an error or no SVG
- Invalid error correction level value (not L/M/Q/H) — likely 400 or default fallback
- Scale value outside 1-20 range — rejected or clamped
- Border value outside 0-10 range — rejected or clamped
- Version outside 1-40 range — rejected
- Text empty or missing — required field error
- Text too long for any QR version (>~7000 chars at version 40) — capacity exceeded error
