Phone QR Code Generator | One-Scan Dialer Trigger

FAQ

Are phone numbers sent to a server when I generate the QR code?↓

No. Phone QR Generator renders the QR matrix locally in your browser using a JavaScript encoder. Your phone numbers never leaves the device, never reaches our servers, and is never logged. The only network traffic is the page itself loading — generation is fully offline-capable after that.

In what formats can I download the QR code?↓

You can download as PNG (raster, perfect for screens, slides, and most print jobs) or SVG (vector, scales to any size without quality loss — ideal for posters, packaging, and large displays). Both formats embed the data directly so the file works without any external dependency.

Will the QR code scan reliably with phone cameras?↓

Yes. Phone QR Generator uses standard QR code specification with adjustable error correction (Low, Medium, Quartile, High). Default Medium tolerates ~15% damage to the matrix, so prints with smudges, folds, or partial obstruction still scan. iOS, Android, and dedicated scanner apps all decode the output without extra apps.

Can I customize size, colors, or add a logo?↓

Yes. Adjust pixel size for the target medium, change foreground and background colors (keep contrast above 4.5:1 for reliable scanning), and overlay a center logo up to ~20% of the matrix area. Higher error-correction levels let you push the logo size further without breaking scanability.
