QR Code Generator
Create a QR code for any URL or text, and download it as a PNG. No watermark, no expiry.
How to use this tool
- Fill in the options above.
- The result updates as you change the input — there is nothing to submit and nothing to wait for.
- Read the figures in the result panel.
- Use Copy or Download if you need the output elsewhere. Nothing was uploaded at any point.
This generates a static QR code — the data is encoded directly in the pattern, so it works forever and needs no service behind it. Many free QR sites produce tracking redirects that stop working when the account lapses or the company folds.

How it works
This tool runs entirely in your browser. There is no server involved, which means nothing you type or upload is transmitted, stored, or logged — and there are no usage limits, because there is nothing for us to ration.
You can confirm it yourself: open your browser's developer tools, select the Network tab, and use the tool. No request is made.
A worked example

What came back
Fill in the fields on the left and the result appears here.
Everything above happened in the page as the text was typed. Nothing was sent to a server, which is why it works offline once the page has loaded and why there is no limit on how often you use it.
Who needs QR Code Generator
Menus, posters, packaging, business cards, Wi-Fi sharing, event tickets — anywhere a printed link needs to be scannable.
QR Code Generator — frequently asked questions
Will this QR code expire?
No. The data is encoded in the pattern itself, so there is no server involved and nothing to lapse. Codes from services that redirect through their own domain stop working if that service disappears.
Which error correction level should I use?
M (15%) suits most uses. Choose H (30%) if the code will be printed small, placed on a curved surface, or partly covered by a logo — it tolerates more damage at the cost of a denser pattern.
How small can I print it?
As a rule of thumb, at least 2 × 2 cm for a scan at arm’s length, and larger for greater distances. Always keep the quiet zone — the blank border — or scanners struggle.
Does it track scans?
No. There is no tracking, no analytics, and no redirect. The code points directly at whatever you entered.
Does this work offline?
Yes. Once the page has loaded you can disconnect from the internet and it keeps working, because all the processing happens in your browser. That is also the simplest way to confirm nothing is being sent anywhere.
Is there a limit on how much I can paste in?
Nothing we impose. The practical limit is your device’s memory, since the work happens locally. Very large inputs get slower rather than being refused.
