QRBuilt is a free, no-sign-up online tool for generating QR codes. Every code is created locally in your browser using JavaScript — your input data is never sent to any server. The tool supports seven QR code types: 1. **URL** — links to any web address 2. **Text** — plain text or arbitrary content 3. **vCard** — digital business card with name, phone, email, organization, address 4. **WiFi** — network credentials (SSID, password, security type) for one-tap joining 5. **Email** — mailto: link with optional subject and body 6. **SMS** — pre-filled SMS message 7. **Phone** — tel: link for one-tap calling ## Key facts - **Price:** Free for unlimited use. No subscription, no sign-up, no premium tier. - **Privacy:** 100% client-side. No server processes the user's data. No analytics on QR content. - **AdSense:** Used for monetization. Ads are paused by default until the user gives consent via the cookie banner. Default consent state is non-personalized ads. - **Downloads:** PNG (raster), SVG (vector), EPS (vector for print). - **Customization:** Foreground and background colors, size slider (100-500px), four error-correction levels (L, M, Q, H), logo overlay (PNG/SVG up to 5MB). - **Browser support:** Modern evergreen browsers (Chrome, Firefox, Safari, Edge).

Fill in the form fields for that type 4. Customize size, colors, and error-correction in the Style tab 5. Optionally upload a logo in the Logo tab (PNG or SVG, up to 5MB) 6. Click **Save** to download the QR code as PNG, SVG, or EPS The QR code updates in real time as you type. No "generate" button needed. ## URL QR codes For URL QR codes, two optional fields are available: - **Campaign Parameters** — append UTM tags (e.g., `utm_source=twitter&utm_medium=social`) to any URL - **Custom Label** — set a custom filename for the downloaded QR code The URL handler supports any URL scheme (http, https, mailto, tel, etc.) and properly merges query parameters without double-encoding. ## WiFi QR codes WiFi QR codes store network credentials in the standardized `WIFI:` URI format. The codes are recognized natively by: - iOS 11 and later (Camera app) - Android 10 and later (Camera app) Supported security types: WPA/WPA2, WEP, and open (no password). The QR code stores the exact security type so phones connect with the correct protocol. Common placements: cafes and restaurants on every table, hotels at check-in desks and inside rooms, offices in meeting rooms and reception areas, retail stores at the entrance, and home on the fridge or near the router. ## vCard QR codes vCard QR codes use the vCard 3.0 format. Scanning saves the contact directly to the phone's address book without typing. Supported fields: first name, last name, job title, organization, phone, email, website, street, city, state, ZIP, country. ## Use cases The site has dedicated landing pages for common QR code applications: - **WiFi QR Code** (https://www.qrbuilt.com/use-cases/qr-code-for-wifi) — for guest networks, restaurants, hotels - **vCard QR Code** (https://www.qrbuilt.com/use-cases/vcard-qr-code) — digital business cards - **QR Code for Business** (https://www.qrbuilt.com/use-cases/qr-code-for-business) — marketing, packaging, menus, signage Each use-case page is available in six languages (en, de, fr, es, it, zh). ## Blog / Guides - **How to Create a QR Code** (https://www.qrbuilt.com/blog/how-to-create-qr-code) — 4-step beginner guide - **WiFi QR Code Guide** (https://www.qrbuilt.com/blog/wifi-qr-code-guide) — detailed WiFi setup - **QR Code Marketing Tips** (https://www.qrbuilt.com/blog/qr-code-marketing-tips) — engagement strategies ## Frequently asked questions **Q: Is QRBuilt really free?** A: Yes. There is no paid tier, no sign-up, and no limit on the number of QR codes you can generate. **Q: Is my data private?** A: Yes. All QR generation happens locally in your browser. Your input is never sent to any server. There is no analytics on what QR codes you create. **Q: Do I need to create an account?** A: No. QRBuilt requires no sign-up or account of any kind. **Q: Can I add my logo to a QR code?** A: Yes. Click the Logo tab and upload a PNG or SVG (up to 5MB). The logo is embedded in the center of the QR code. You may need to use a higher error-correction level (Q or H) to keep the code scannable with a logo. **Q: What file formats can I download?** A: PNG (raster for digital use), SVG (vector for scaling), and EPS (vector for professional print). **Q: What error-correction level should I use?** A: Use L (Low, ~7%) for clean codes with no logo, M (Medium, ~15%) for general use, Q (Quartile, ~25%) when adding a logo, and H (High, ~30%) for codes that may get damaged (printed on products, outdoor signage). **Q: Do WiFi QR codes work on all phones?** A: Yes, on iOS 11+ and Android 10+, the built-in camera app recognizes WiFi QR codes natively. Older phones may need a QR scanner app that supports WiFi network joining. **Q: Are WiFi QR codes secure?** A: Print them only for trusted guests. The QR code exposes the WiFi password to anyone who scans it. For businesses, use a separate guest network with its own QR code. **Q: Which WiFi security types are supported?** A: WPA/WPA2 (most common modern standard), WEP (legacy for older devices), and open networks with no password. ## Privacy and data - QRBuilt does not collect, store, or transmit QR code content. - AdSense is used for display ads.
