QR Code Generator

Generate a QR code for a URL, plain text, WiFi network, contact card, or email — pick the type, fill in the fields, and the code updates live. Download it as a PNG for quick use or an SVG when you need it to scale cleanly to any size (print, signage, large format). You can set the size, recolor the code and background, and choose the error-correction level.

The typed modes save you from remembering QR data formats. WiFi builds a code that phones can scan to join a network without typing the password; Contact creates a vCard that adds a person straight to the address book; Email pre-fills a message. For everything else, URL and Text just encode what you enter.

It all runs in your browser, so nothing you enter — including WiFi passwords or contact details — is sent to a server. The QR codes are standard and permanent: they don't expire, don't track scans, and don't route through a redirect.

Codes are generated client-side with the qrcode library and drawn to a canvas for the PNG, or rendered as vector markup for the SVG download. Each mode assembles the standard payload string: WiFi uses the WIFI:T:...;S:...;P:...;; format, Contact builds a VERSION 3.0 vCard, and Email produces a mailto: URI with URL-encoded subject and body. URL and Text encode their content directly.

Error correction is the tradeoff worth understanding. Higher levels (Q at 25%, H at 30%) add redundant data so the code still scans even if part of it is damaged, dirty, or covered — but they also make the pattern denser. Lower levels (L at 7%, M at 15%) keep the code simpler and easier to scan at small sizes but tolerate less damage. M is a sensible default; bump to H only if the code will be printed small, placed where it might get scuffed, or overlaid with a logo.

The SVG export is resolution-independent, so it's the right choice for print. Custom colors work, but the code needs strong contrast (dark on light) to scan reliably. Nothing is uploaded.

Dynamic QR services (Bitly, QR generators with dashboards) give you editable destinations and scan analytics, but the code routes through their redirect — which means it can break if they change their service, and they track every scan. This tool makes static QR codes: the data is baked into the pattern, so it works forever, has no middleman, and collects nothing. The trade-off is you can't change the destination after printing.

For a permanent link, a WiFi code on a wall, or a contact card that just works offline, static is what you want. Choose a dynamic service only when you specifically need to edit the target later or measure scans — and accept the dependency and tracking that come with it.
