Free QR Code Generator
Choose URL, text, or Wi-Fi and watch a static QR code update as you type. Download PNG or SVG in your browser — your content stays on your device.
Developer notes
• Encoding uses qrcode 1.5.4 with library margin 0; page margin is applied in px (PNG) or as a quiet-zone ratio (SVG). • Wi-Fi strings follow WIFI:T:…;S:…;P:…;H:…;; with standard field escaping. • PNG rasterizes via canvas in the browser; SVG is vector output from the same payload.
Options
Content type
Switches between URL, free text, and Wi-Fi join payloads, including which input fields are shown.
Colors
Sets foreground (modules) and background colors for both SVG and PNG exports.
Error correction
Chooses L, M, Q, or H redundancy. Medium (M) is the default.
Quiet zone
Padding in pixels around the symbol in the PNG; the SVG uses the same margin ratio.
PNG size
Square side in pixels for the downloaded PNG only.

When this is the right tool
• You need a static QR for a URL, plain text (including mailto:), or Wi-Fi join details. • You want PNG and SVG files without an account, upload, or scan analytics. • You prefer a live preview that follows typing, not a gated download step.
QR Code Generator FAQ
Browser-local static QR codes
Is my URL or Wi-Fi password sent to a server?
No. Encoding, preview, and downloads run entirely in your browser.
Does this track scans or shorten links?
No. The symbol encodes exactly what you type — no dynamic redirect or analytics.
Can I encode a mailto: link?
Yes. Use the text type and paste the full mailto: string.
Why does changing PNG size not change the SVG?
PNG size only affects the raster download. The SVG keeps the same quiet-zone ratio and vector modules.
Barcode labels
Draw Code 128, EAN-13, and UPC-A label images in the browser — PNG and SVG download, not a GS1 lookup.
