QR Code Generator & Reader API

Web & SEO Tools

Operated by Sourcelane✓ verified

A QR code generator and reader that encodes arbitrary text or URLs (including Wi‑Fi credentials, vCards, and other strings) into PNG QR code images and decodes text from existing QR code images. The connector supports batch processing of large lists, configurable image size and error‑correction level for generation, and decoding from image locations or embedded image data; outputs consist of a generated QR code image expressed as a data URI for each input when encoding, or the decoded text string when reading.
