QR code generator
Turn any text, a URL, or Wi-Fi credentials into a QR code, then download it as a crisp PNG or a scalable SVG. Pick the error-correction level to trade size for resilience. Everything runs in your browser - nothing is uploaded.
How it works
Type any text or a URL and a QR code is generated instantly, right in your browser. QR codes are a quick way to move a link, a piece of text, or contact details to a phone: point a camera at the code and it opens. A Wi-Fi mode builds the special credential format so a guest can join your network by scanning, without you reading out the password. The error-correction level is adjustable, trading a little capacity for the ability to still scan when the code is partly obscured or printed small.
When it looks right, download it as a PNG for documents and slides, or as a crisp SVG that scales to any size for print. The code is generated locally on your machine using a bundled encoder, so whatever you encode - a private URL, a network password - is never sent to a server.
Example. Paste https://godz.online and a QR code appears that opens the site when scanned. Switch to Wi-Fi mode, enter your network name and password, and the generated code lets a guest join the network by pointing their camera at it. Download the result as an SVG to drop into a printed flyer.
FAQ
What can I put in a QR code?
Anything that fits as text: a URL (the most common use, which opens when scanned), plain text, an email address, or a phone number. This tool also has a Wi-Fi mode that assembles the standard WIFI: credential string so a scan offers to join the network. Larger amounts of text produce a denser code; very long inputs may need a lower error-correction level to fit.
What is the error-correction level?
QR codes include redundant data so they still scan when part of the code is dirty, damaged, or covered, for example by a logo. The level (L, M, Q, or H) sets how much redundancy is added, from about 7 percent up to about 30 percent. A higher level is more robust but stores less data in the same size, so the code gets denser for the same text.
What is the difference between the PNG and SVG download?
PNG is a raster image at a fixed pixel size, which is convenient for screens, documents, and slides. SVG is vector, so it stays perfectly sharp at any size, which is what you want for print or a large display. Both encode exactly the same QR code; pick the format that suits where it will be used.
Is my data sent anywhere?
No. The QR code is generated entirely in your browser by a bundled encoder, and the download is built locally. Nothing you type, including a Wi-Fi password, is uploaded, logged, or stored, so it is safe to encode private links and credentials.
