Overview

Generate stylized, brand-aligned QR codes with custom shapes, color gradients, and embedded logos while validating scannability through ISO mask-penalty analysis and Reed–Solomon erasure-budget checks.

When to use

Designing branded marketing collateral that requires a custom visual identity without sacrificing QR scan reliability.
Embedding an icon, emoji, or company logo in the center of a QR code while verifying error-correction capacity.
Exporting vector graphics and per-module coordinate metadata for print-ready designs and custom rendering pipelines.

How it works

1Input your target URL or text payload and select an error correction level from L (7%) up to H (30%).
2Customize module rendering styles (solid, diagonal gradient, rounded, or dots) and set brand color palettes.
3Upload a center logo image or add badge text, then set the badge scale and quiet zone width.
4Review the ISO/IEC 18004 mask-penalty breakdown and Reed–Solomon budget verdict, then export SVG, PNG, PDF, or per-module JSON.

Use cases

Creating vector SVG and PDF QR codes for physical product packaging and high-resolution print posters.
Embedding app icons or brand marks into promotional campaign landing page links.
Extracting per-module JSON coordinates to render programmatic 3D models or custom canvas animations.

Examples

1. Branded Marketing Campaign QR

Brand Designer

Background

A designer needs a print-ready QR code for an outdoor billboard campaign that incorporates the corporate violet palette and star icon.

Problem

Standard black-and-white QR codes do not match brand guidelines, but custom styling risks making the code unreadable.

How to use

Enter the campaign URL, select Error Correction Level H, choose diagonal gradient mode with brand hex values, enter the star badge text at 20% scale, and export SVG.

{
  "payload": "https://brand.example.com/promo",
  "eccLevel": "H",
  "styleMode": "gradient",
  "darkColor": "#1a1a2e",
  "accentColor": "#7c3aed",
  "lightColor": "#ffffff",
  "badgeText": "★",
  "badgeScalePercent": 20,
  "quietZoneModules": 4
}

Outcome

A vector SVG QR code with smooth gradients and a center badge that passes the Reed–Solomon erasure budget check.

2. Minimalist Dot-Grid Product Manual Link

Technical Writer

Background

A technical documentation team wants to include a subtle dot-grid QR code inside a printed user quick-start guide.

Problem

Large solid blocks look too heavy on minimal manual layouts, and the team needs high-density data storage without a logo overlay.

FAQ

Why does functional geometry remain in the high-contrast base color?

Finder and timing patterns keep the base dark color to ensure camera scanners quickly detect symbol alignment.

What error correction level should I use when adding a center logo?

Level H (30%) or Level Q (25%) is recommended to give the Reed–Solomon erasure budget enough capacity for the covered area.

What file formats can I upload for the center logo?

The generator accepts PNG, SVG, and WebP image files up to 5 MB.

What does the ISO mask-penalty score evaluate?

It evaluates the symbol across the four ISO/IEC 18004 rules (N1–N4) to identify patterns that might hinder optical reading.

Which export formats are available for the final QR code?

You can download the generated QR code as SVG, PNG, PDF, or download the raw per-module coordinate data in JSON format.

{
  "payload": "https://docs.example.com/manual/v2",
  "eccLevel": "L",
  "styleMode": "dots",
  "darkColor": "#111827",
  "accentColor": "#111827",
  "lightColor": "#ffffff",
  "badgeScalePercent": 0,
  "quietZoneModules": 4
