QR Generator

The QR Generator renders a scannable QR code from any text or URL and exports it as a downloadable PNG, all in the browser. Type or paste your content into the Text or URL field, and the code re-renders live as you type. A Size slider ranges from 128 to 1024 pixels in 16-pixel steps, giving you a small code for a screen or a large one for print. The Error correction select offers four levels — L at 7% recovery, M at 15%, Q at 25%, and H at 30% — so you can tune how much damage the code survives during scanning versus how densely it packs data. Foreground and Background color pickers let you match a brand palette, and each swatch also accepts a typed hex value. The generated image draws with the standard quiet-zone margin around the modules, and it appears in a bordered preview card that grows to fit the chosen size up to a preview ceiling. Download PNG exports the canvas as a PNG file named qr-code.png, and a Scan Tip button reminds you that lighter backgrounds scan best, while a small helper note appears when the field is empty.

1. 1

   Enter the URL or any text into the Text or URL field; the preview updates live on every keystroke.

2. 2

   Drag the Size slider to your target dimension — the hint shows the exact pixel value, from 128 up to 1024.

3. 3

   Pick an Error correction level from L (7%), M (15%), Q (25%), or H (30%) based on how the code will be used.

4. 4

   Set the Foreground and Background colors with the swatch pickers or by typing hex values into their fields.

5. 5

   Click Download PNG to save the canvas, and use Scan Tip for a reminder that lighter backgrounds scan best.

• Marketing print — a poster-safe 1024px QR at low correction links billboards, flyers, and packaging back to a campaign landing page.
• Event badges and lanyards — high error-correction codes survive lanyard folds and badge scuffs while carrying the attendee landing URL.
• Product labels — small, dark-on-light codes on packaging give shoppers a direct route to instructions or ingredient pages.
• Wi-Fi access cards — a WIFI: string encodes the network name and password so guests scan instead of typing credentials.
• Table menus — a middle-size QR at M level on near-white background sends diners to the digital menu without printing a long URL.
• Inventory and tracking — batch codes embed serialized identifiers that warehouse scanners read reliably at normal distances.

• Keep foreground dark and background light; scanners lock onto contrast, and light-on-dark codes fail with cheaper readers.
• Choose high error correction for anything printed, laminated, or handled, since scratches and wrinkles recovery the H level recovers.
• Preserve the quiet zone around the code in your layout; the generator adds a 2-module margin and design cropping removes it, browsers read it anyway.
• Test the code with a camera at the real range and lighting before printing a whole run; a preview on screen is not proof of scannability.
• Point codes at stable, short URLs rather than deep links that might be reorganized, and regenerate if a target URL ever changes.
• Export at the largest size you will need; upscaling a small PNG later only blurs the modules instead of sharpening them.

• Generate a quick code for your Wi-Fi network and laminate it; guests scan once and connect without explaining the password.
• Use high correction for anything on fabric or curved surfaces, where scanning angles and wrinkles eat into the recoverable damage budget.
• Re-scan the output PNG after changing colors to confirm the download still reads before you commit to the design.
• Regenerate codes when a URL changes rather than keep stale ones; a QR cannot be edited after printing, only regenerated and reprinted.
