SMS QR Code Generator | Prefilled Number & Message

FAQ

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

No. SMS QR Generator renders the QR matrix locally in your browser using a JavaScript encoder. Your phone numbers and messages 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. SMS 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.

What this QR code does

An SMS QR code opens the messages app with the phone number and a starter text already filled in. It lowers friction for lead capture, appointment requests, and support flows that still rely on text messages.

How to set it up

Add the destination number, write a short prefilled message, and test the QR on real devices. The starter message should be short enough to edit quickly if the user wants to personalize it.

Best use cases

Use SMS QR codes on outdoor ads, printed coupons, event stands, waitlist cards, and service instructions where text is easier than filling a full form.
