Introduction
The QR Code Generator helps you create scannable QR codes for plain text, website links, phone numbers, email actions, SMS messages, and Wi-Fi network sharing. It also includes styling controls for templates, colors, dot shapes, captions, quiet zone spacing, and a centered logo, all processed locally in the browser.
How to Use
Choose a content type first, then fill the required fields such as URL, phone number, email address, SMS message, or Wi-Fi settings. Pick a visual template or customize colors, dot shape, eye style, error correction, logo size, and caption text. Review the live preview, check the scan safety notes, then export the result as PNG or SVG.

Practical Use Cases
QR codes are useful whenever you want to move people quickly from a physical or visual touchpoint into a digital action. Common examples include product packaging, event posters, restaurant menus, classroom handouts, presentation slides, landing pages, payment instructions, and guest Wi-Fi cards.
Why Styling Needs Restraint
A QR code can look better with brand colors, rounded dots, a logo, or caption text, but every decorative choice reduces scanning tolerance a little. High contrast, a clear quiet zone, and a modest logo size matter more than visual novelty. If a code will be printed small or used in low light, a simpler style is usually safer.
When to Use Higher Error Correction
Error correction helps scanners recover a QR code even when some modules are hidden or damaged. If you add a centered logo, place the code on print materials, or expect the surface to get scratched or folded, Q or H is generally a better choice than L or M.
Local Processing and Privacy
The generator works locally in the browser. That makes it convenient for quick creation and internal workflows, but you should still avoid putting secrets, private customer data, one-time access codes, or sensitive network credentials into shared QR graphics unless your policies allow it.
QR Content Type Guide
Choose the payload type that matches the action you want people to take.
| Type | Encodes | Typical Use |
|---|---|---|
| Text | Plain text | Short notes, IDs, codes, or instructions |
| URL | Website link | Landing pages, menus, downloads, campaigns |
| Phone | tel: action | Support lines, bookings, sales contact |
| mailto: action | Customer enquiries or support requests | |
| SMS | SMSTO payload | Short text prompts or opt-in flows |
| Wi-Fi | Network credentials | Guest network sharing |
Scan Safety Checklist
Small design choices can improve or harm scan reliability.
| Setting | Safer Choice | Risk When Overdone |
|---|---|---|
| Foreground vs background | Strong contrast | Low contrast makes scanning harder |
| Quiet zone | At least 4 modules | Scanners may miss the edges |
| Logo size | Small and centered | Large logos can block too many modules |
| Dot styling | Mild customization | Heavy styling can reduce readability |
| Error correction | Q or H with logo | Low levels are less tolerant of damage |
Frequently Asked Questions
Is the QR code generated locally?
Yes. The content payload, styling, logo overlay, and export are processed in your browser without uploading data to a server.
Which export format should I choose?
PNG is convenient for slides, social posts, and quick sharing. SVG is better for print and design tools because it stays sharp when scaled.
Can I add a logo in the center?
Yes. Keep the logo relatively small and use Q or H error correction so the QR code stays easier to scan.
What is the quiet zone around a QR code?
It is the empty margin around the code. Most QR codes scan more reliably when the quiet zone is at least 4 modules wide.
Should I use transparent backgrounds?
Transparent backgrounds can look clean on screens, but printed QR codes usually work better with a solid background and strong contrast.
