How to make a QR code for links, wifi, or text

QR codes have quietly become the easiest way to hand someone a link without them typing anything — a menu, a wifi password, a contact card, a payment link. ToolboxTree's free QR Code Generator creates one instantly, entirely in your browser, with nothing uploaded anywhere.

What you can put in a QR code

Most QR codes just point to a link, but they can hold any text — a wifi network name and password formatted for auto-connect, a phone number, a short message, even emoji. The generator handles Unicode and emoji input fine, so it's not limited to plain URLs.

Picking a size and error-correction level

The error-correction setting controls how much of the code can be damaged, covered, or printed slightly blurry before it stops scanning — higher correction adds a bit more visual complexity to the code but makes it more forgiving, which is worth it for anything going on a poster, sticker, or table tent rather than staying on a screen. Larger sizes scan more reliably from a distance, so size it up for anything printed and going on a wall.

Downloading it

Once it looks right, download as PNG for quick sharing or printing, or SVG if you need it to stay crisp at a much larger size — a poster or shop window, for example — without losing quality.
