What is QR Code Generator?

Turn any text, URL, or data into a scannable QR code in seconds. Generate the code, preview it on screen, and save it as an image. Nothing is uploaded. Everything happens on your device.

Encodes anything you paste, from URLs to receipt notes, into a Version 1-40 QR symbol with four error-correction tiers (L, M, Q, H). Render sizes run from 128 to 2000 pixels — large enough for posters, signage, and product labels — and you can swap foreground and background colors for brand matching. Add an optional caption frame with a short label like Scan me so a printed code explains itself. Higher EC levels survive smudges, creases, or a logo dropped over the centre.

How to use

1. Step 1 — Type or paste the text, URL, or data you want to encode.
2. Step 2 — The QR code generates instantly as you type, updating in real time.
3. Step 3 — Download as PNG, SVG, or PDF, or copy to your clipboard.

When to use

• Posting a payment link on a flyer or shop sign so people scan instead of typing a long URL.
• Encoding a serial number or asset tag on equipment labels for quick warehouse scanning.
• Sharing a Telegram, WhatsApp or signal-channel invite link on a poster at a meet-up.

Result

Paste your business website URL 'https://example.com' and instantly get a QR code you can print on your business cards for easy scanning.

FAQ

How much data fits in one QR code before it stops scanning reliably?

The hard ceiling is about 4,296 alphanumeric or 2,953 raw bytes at the largest version. In practice anything past 500-700 characters becomes visually dense and phones struggle to lock on without a steady hand. Trim or shorten where possible.

What's the difference between EC levels L, M, Q, and H?

L tolerates about 7% damage, M about 15%, Q about 25%, and H about 30%. Higher levels add redundancy so the code keeps scanning when scuffed or partially covered, but the pattern becomes denser at the same content length.

Why won't my phone scan a code I just generated?

Three usual suspects: not enough quiet zone (the white border), foreground and background colors too close in contrast, or the code is too small for the camera resolution. Aim for at least four module-widths of white around the code and a dark-on-light combo.

Can I edit a QR code after printing it?

Static codes from this generator are immutable; the content lives inside the pattern itself. If you need to change the destination later, encode a short URL you control and update the redirect on your server.

Are special characters and emoji safe to encode?

Yes, the encoder switches to byte mode automatically and writes UTF-8. Just remember every multi-byte glyph costs more capacity, so an emoji-heavy message hits the size limit far sooner than plain ASCII.
