QR Code Generator

Turn a link, a note, a WiFi password, or a contact card into a scannable QR code — right here in your browser. Nothing you type is ever sent anywhere.

Why a scan might fail

Screen size vs. distance

A QR code that's too large on a small screen forces the camera too close to fit it in frame. Try "Small" or "Medium" and hold the phone a bit further back.

Very long text

Long links or WiFi details create a denser, harder-to-read pattern. Shortening the link (or using a link shortener) makes it easier to scan.

What each type does

Link

Opens a website the instant it's scanned — perfect for menus, business cards, or packaging.

Text

Shows a plain message on the scanner's screen — no app or internet connection needed to read it.

WiFi

Connects a phone to your network automatically — no more spelling out a password to guests.

Contact card

Saves your name, number, and email straight into someone's phone contacts with one scan.
