QR Code Generator

  • Browser-based
  • No signup

Enter text or a URL, choose size, error correction, margin, and colors, then generate a downloadable PNG QR code. Generation runs entirely in your browser.

QR codes encode whatever text you provide—URLs, Wi-Fi join strings, or vCard contact blocks. Test the scanned result on a real phone before printing posters or packaging because a single typo creates a dead code.

High error correction tolerates logo overlays in the center of marketing QR art. Increase error correction when you place a brand mark on top of the code pattern.

Use a URL shortener when the encoded link is very long—shorter payloads scan more reliably on low-resolution prints.

Restaurant menus and event posters should use HTTPS landing pages—some phone cameras warn on plain HTTP destinations.

vCard QR codes for networking events should include a tested phone format with country code so international scanners dial correctly.

Print QR codes at least one inch square on packaging so warehouse scanners read them from a normal handheld distance.

100% Client-Side

Your data never leaves your computer.

How to use this tool

1. Enter text or a URL in the input area. 2. Set size, error correction level, and margin. 3. Choose foreground and background colors. 4. Click Generate QR code. 5. Download the PNG when the preview looks correct.

Worked example

Example: URL https://utilnivo.com at 256 px, error correction M, default colors—scan the downloaded PNG to open the site.

When to use this

  • Wi-Fi onboarding posters with SSID and password encoded.
  • Event check-in URLs on printed flyers.
  • vCard contact blocks on business cards.
  • UTM-tagged landing page links on packaging.

Common examples

  • Wi-Fi network SSID + password → QR for guest onboarding poster.
  • Event check-in URL with UTM parameters → QR on printed flyer.
  • vCard contact block → QR on business card PDF.
  • Restaurant table ordering URL with `?table=12` → print on tent card.
  • App Store link with campaign query → QR on conference banner.

Common mistakes

  • Encoding URLs without `https://` so phones treat them as search text.
  • Making QR too small or low contrast to scan reliably.
  • Using a long URL when a short redirect would scan faster.
  • Forgetting to test scan under real lighting before printing.

Related long-tail tasks

  • build UTM link before QR encoding
  • create Wi-Fi QR with hidden password
  • generate vCard QR for contact card
  • resize QR image for print poster
  • scan QR locally to verify payload

How it works

Enter text or a URL, choose size, error correction, margin, and colors, then generate a QR code. The image is created in your browser as a PNG you can download. Nothing is uploaded or stored.

Limitations

Generated codes are static images. Test scanning at the intended print size before production use.

Privacy and file handling

Your data is processed in your browser and is not uploaded to our server.

Frequently asked questions

What can I encode in a QR code?

Any text or URL up to 1000 characters. Common uses include website links, contact details, and short messages.

What does error correction do?

Higher error correction makes the code more readable when damaged or partially covered, but uses more of the QR pattern. Medium (M) is a good default.

Is my text stored?

No. QR codes are generated locally in your browser and input is not stored.
