QR Generator

Convert any text or URL into a QR code directly in your browser.
You can customize the size in pixels, adjust foreground and background colors, and instantly preview the generated QR code on the screen.

Once generated, the QR code can be exported as a PNG image with a single click, making it suitable for documents, presentations, printed materials, or sharing links online.

All QR code generation is performed locally on your device.
No input text, URLs, or generated images are uploaded to any server, allowing you to create and download QR codes quickly and securely.

Guide: How to use & features

  • Type or paste text or links into the input field to update the preview automatically.
  • Customize size, margin, and foreground/background colors to suit your needs.
  • Click “Save image” to download the QR code as a PNG file.
  • All generation happens locally—no input data is uploaded.

FAQ: Frequently asked questions

  • How much text can I encode?

    A few hundred characters usually scan well on most phones. For very long text, consider shortening it first.

  • Can I change the error-correction level?

    Yes. Adjust the level to fit your use case—higher levels improve recovery but reduce capacity.

  • Which download format is available?

    You can download the code as PNG. Set the color and size before exporting.

Use cases: Common use cases

  • Sharing links or Wi‑Fi details

    Generate QR codes for URLs or SSIDs and drop them into event decks or printouts for instant access.

  • Creating test QR codes

    Vary the encoded strings to produce multiple QR samples and verify scanner behavior across devices.

  • Embedding in branded materials

    Adjust corner radius and colors to create QR images that fit your promotional assets.

Notes: Notes & limitations

  • Work stays in your browser

    Inputs and outputs remain local. Closing the tab or clearing cache will remove any temporary state.

  • Validate critical data

    Results are helper outputs—double-check them before sending to production systems or sharing externally.

  • Large payloads depend on your device

    Very large text or files can feel slow in some browsers. Use a desktop environment for heavy workloads.

QR Code Generator

This QR code generator turns URLs, text, contact details, Wi-Fi information, or short messages into scannable QR codes. It is useful for landing pages, printed materials, event signs, internal documentation, product packaging, and quick mobile testing.

Common uses

  • Share URLs: Create QR codes for websites, forms, docs, and campaign pages.
  • Prepare print assets: Add QR codes to flyers, posters, business cards, manuals, or handouts.
  • Test mobile flows: Open local, staging, or preview URLs on a phone without typing long links.

Make QR codes easier to scan

Shorter content creates simpler QR codes. Keep enough margin around the code, use strong contrast between foreground and background, and test the final image at the size where it will actually be printed or displayed.
