What does the error-correction level do?

It controls how much of the code can be damaged or covered and still scan. Higher levels add redundancy — useful for logo overlays or rough print conditions — but make the code denser. Lower levels keep it simpler.

Can I put a logo or change the colours?

Yes. You can change the foreground and background colours and module style. Keep strong contrast between foreground and background, and raise the error-correction level if you overlay a logo, so the code stays readable.

Can I generate many QR codes at once?

Yes. Add multiple entries and the tool generates a code for each, then lets you export the whole batch to PNG or PDF in one step.

Why won't my QR code scan?

The most common causes are too little contrast between the colours, the code printed too small, or a logo covering too much of it. Increase contrast, print larger, or raise the error-correction level.

Is the data I encode sent anywhere?

No. QR codes are generated entirely in your browser, so the URL or text you encode is never uploaded or stored.

About QR Code Generator

A QR code packs a URL, a piece of text, contact details, or Wi-Fi credentials into a square that any phone camera can read in a second. They've become the standard bridge from print to screen — on posters, packaging, menus, and business cards — because they remove the friction of typing a long address by hand.

This generator lets you create a single code or a whole batch at once, and customise how it looks: choose the error-correction level, adjust the foreground and background colours, and pick a module style so the code matches your brand while staying scannable. Higher error correction lets the code survive a logo overlay or a bit of print damage at the cost of density. When you're happy, export a sharp PNG for screens or a print-ready PDF.

Codes are generated in your browser and never uploaded. The text or URL you encode stays on your device, so you can produce codes for unpublished links or private data without them leaving your machine.

How to use QR Code Generator

Enter the content
Type the URL or text you want the QR code to encode. Add more entries to generate several codes at once.
Pick an error-correction level
Choose a higher level if the code will be overlaid with a logo or printed in a setting where it might get scuffed; choose lower for a denser, simpler code.
Style the code
Adjust the colours and module style so the code fits your design while keeping enough contrast to scan reliably.
Generate and export
Generate the code, test that it scans, then export as PNG or PDF. Bulk mode exports the whole set together.
