QR Code Generator
Create QR codes for URLs, text, WiFi, email, and phone numbers.
QR codes turn links, contact details, and WiFi credentials into scannable squares that phones read in seconds. Utilitoo's QR Code Generator creates those codes in your browser - no app install, no account, and no upload of your content to a server.
Restaurant owners print menu links on table tents. Event organizers share registration URLs on posters. Small shops add payment or review links to receipts. Developers test deep links and app install flows without opening design software. Home hosts generate WiFi guest codes so visitors join the network without typing long passwords.
Choose a content type: plain text, URL, WiFi network, email address, or phone number. Enter your value, tune size and colors for print or screen, pick an error correction level, and download a PNG ready for slides, flyers, or packaging. Higher error correction (Q or H) helps when part of the code might be covered by a logo or creased on paper.
WiFi mode follows the standard WIFI: QR payload format so iOS and Android cameras offer to join the network after scan. URL mode adds https:// automatically when you omit the scheme. Everything encodes locally on Utilitoo - your passwords, links, and contact data never leave your device.
Pair with Barcode Generator when you also need linear retail or inventory codes, or URL Encoder when debugging special characters in query strings before encoding. Free, instant, and privacy-first for marketers, developers, and anyone who needs a reliable online QR code maker.
QR Code Generator on Utilitoo covers the most common encode-and-download workflow: pick a type, enter content, download PNG. Square QR codes excel at URLs, WiFi, and contact shortcuts scanned by phone cameras. When you need linear retail symbology instead, open Barcode Generator from Related Tools.
Common use cases
- Adding a scannable menu or booking link to restaurant table cards and window posters.
- Sharing WiFi credentials with house guests without dictating a long password.
- Printing event check-in URLs on badges, flyers, or conference signage.
- Testing mobile deep links and app install flows during QA without design tools.
- Embedding contact or payment links on business cards and packaging inserts.
Tips & common mistakes
Use error correction level M for screen display and H for print where logos or folds may cover part of the code. Keep strong contrast between foreground and background colors - pale-on-pale codes fail on phone cameras. WiFi QR codes follow the standard WIFI: payload format; double-check SSID spelling and WPA vs open network before printing. Utilitoo generates QR codes locally - safe for guest WiFi passwords and unreleased campaign URLs.
Common errors
- Code will not scan - low contrast, extreme custom colors, or printing too small are frequent causes.
- WiFi join fails after scan - wrong encryption type, hidden network flag, or typo in SSID/password.
- URL opens wrong page - confirm https:// prefix and test the link in a browser before printing.
How to use
- Choose a content type: Text, URL, WiFi, Email, or Phone.
- Enter the value to encode (or WiFi network details).
- Adjust size, colors, and error correction if needed.
- Download the PNG or copy the encoded payload.
