How to Generate a Custom QR Code Online for Free

Last updated: February 24, 2026

QR codes are everywhere — menus, business cards, event tickets, WiFi sharing, and marketing materials. But most QR generators either charge for customization, plaster watermarks on free outputs, or upload your data to their servers. OneClickPDF generates fully customizable QR codes entirely in your browser — your data never leaves your device.

Step-by-Step Guide

Open the QR Code Generator

Navigate to the QR Code Generator on OneClickPDF. No account or signup required.

Choose your content type

Select what the QR code encodes: URL, plain text, WiFi credentials, vCard contact, email, SMS, or phone number. Each type has specific input fields.

Customize the style

Choose foreground and background colors, dot styles (square, rounded, dots, classy, extra-rounded), corner styles, and optionally upload a logo image to embed in the center.

Download your QR code

Download as PNG (for web and print), SVG (vector, infinitely scalable), or PDF (centered on A4 page). The QR code is generated at your chosen resolution.

Frequently Asked Questions

Will the QR code work with a logo in the center?

Yes. When you add a logo, error correction is automatically set to Q (25% recovery), which means the QR code can still be scanned even with part of it covered by the logo. Keep the logo size reasonable (20-30% of QR area) for best results.

What's the difference between PNG, SVG, and PDF download?

PNG is a raster image at your chosen resolution — good for web and most uses. SVG is a vector format that scales to any size without quality loss — ideal for print design. PDF embeds the QR on an A4 page — convenient for direct printing.

Can I create a QR code for WiFi?

Yes. Enter your network name (SSID), password, and encryption type (WPA/WEP/None). When someone scans the QR code, their phone will automatically connect to your WiFi network.

Is my data sent to any server?

No. The QR code is generated entirely in your browser using JavaScript. Your WiFi passwords, contact information, and other data never leave your device.

Can I scan the QR code with any phone?

Yes. All modern smartphones (iPhone and Android) have built-in QR code scanners in their camera apps. The QR codes use the standard QR format that works universally.
