Guide: generate QR codes for URLs and text
QR codes bridge print, slides, and mobile prototypes to staging URLs, deep links, or Wi-Fi payloads (`WIFI:S:…`). Design tools do not always expose error correction or exact pixel sizing.
Generation uses the browser canvas locally — content is not stored on WebDevTools servers. Download PNG or SVG for mockups and camera tests without shipping to production.
Use for feature-flag demos, event onboarding, or distance scanning tests. Long URLs increase module density — shorten with an internal redirect if scans fail.
Step by step
- Enter URL or text — Prefer absolute HTTPS for links. Plain text works for pairing codes or device serials.
- Tune size and quiet zone — White margin prevents cheap scanner failures. Increase size for projector slides.
- Pick error correction level — Higher levels (Q, H) tolerate a center logo on marketing cards.
- Download and test on a phone — Scan in real lighting before print. Confirm staging vs. production opens correctly.
