QR_LAB.SYS
Browser-only QR, contact, Wi-Fi, message, event, sticker, and NFC-ready payload tools. No public uploads. No server-stored user files.
QR Lab builds phone-readable payloads directly in the browser. Generate QR codes for links, text, local vCards, Wi-Fi login, email, SMS, phone, and calendar events. Local images are read by your browser only and are not uploaded to this server.
[ERROR]: DATA_REQUIRED // PLEASE_ENTER_CONTENT
Missing https:// is added automatically for normal web links.
The QR payload stays lean for scanning. The photo can be embedded in the downloaded .VCF file without touching your server.
QR Style / Local Assets
Safe styling only: colors, quiet zone, logo size, transparent export, SVG, and print layouts. Fancy QR shapes can come later after more scan testing.
Logo stays local in the browser. Too large can hurt scan reliability, so the meter will complain if it gets rowdy.
Privacy mode: this page does not upload QR payloads, photos, or logos. Downloads are generated in the browser after the page loads.
Decode / Verify QR Image
Browser-only verification. The image is decoded locally so you can inspect a QR payload before trusting it.
No QR image decoded yet.
