QR codes & barcodes
Choose a QR code for text or links, or a supported barcode for labels. Both APIs return PNG or SVG bytes and consume one credit per generation.

Generation returns ephemeral media, not a public URL. For optional private persistence, read saving and retrieving outputs.
Start with an event QR code or a warehouse shelf label. Code generation explains the product capabilities.
QR options
QR codes encode text, links or payloads. Choose PNG/SVG, size, quiet-zone margin, colors and L/M/Q/H error correction. They do not host dynamic redirects.
