QR Code Generator

This QR code generator produces standards-compliant QR codes entirely in your browser. It builds the correct encoding for each content type — for example the WIFI: URI for network credentials or the vCard 3.0 format for contacts — then renders it as a styled SVG. The preview, the colors, the logo overlay, and every download (PNG, SVG, or PDF) are computed on your device, so nothing sensitive ever leaves the page.

- Restaurant menus, event schedules, and product landing pages. - Guest WiFi at cafes, hotels, coworking spaces, and Airbnbs. - Digital business cards on badges, packaging, and presentation slides. - Marketing collateral — flyers, posters, and stickers with your brand colors. - Support codes on packaging that dial a hotline or open an email draft. - Event invitations that open the venue directly in a maps app.

- Keep strong contrast between foreground and background — dark on light scans most reliably. - Use error correction H whenever you add a logo or plan to print on rough surfaces. - Test your code with two or three different phones before printing at scale. - Export SVG for anything you plan to resize or print larger than a business card. - For long URLs, prefer a branded short link — smaller codes scan from further away. - Give the code some quiet space around it in your design so scanners can lock on.

- Very large payloads (long text, multi-line vCards) produce dense codes that are harder to scan from a distance. - Extremely low contrast, inverted colors, or pale foregrounds may fail to scan. - The logo overlay is rendered on top of the code — always test after adding one. - QR codes do not encrypt content; anyone who scans can read the encoded data.
