QR Code Generator

QR code generators output QR code images from input data (URLs, text, contacts, Wi-Fi settings). Available as free browser tools, desktop apps, CLI tools, APIs, and enterprise platforms.

Selection criteria vary by use: free online tools for personal/small-volume use, paid platforms with dynamic codes and analytics for marketing, and APIs/libraries (Python qrcode, JavaScript qrcode-generator, Java ZXing) for developer integration.

Security consideration: free tools may store input data on servers. For sensitive data, use offline tools or services with clear privacy policies.
