QR codes generated privately in your browser
Enter a link or text and get a scannable QR code, generated locally in your browser so your data never leaves your device.
For the best results: Paste the full link including https://. For print, choose the large size and high error correction. Test the printed code with your phone before mass-producing anything.
Generated locally in your browser, what you type is never uploaded, logged, or sent to any server.
What is QR Code Generator?
QR Code Generator is a free productivity tool that creates scannable QR codes from links or text, generated locally in your browser so nothing is ever uploaded. It runs entirely in your browser, so what you enter is never uploaded, logged, or sent to any server, and it keeps working even offline. No account or subscription is required, and nothing is stored.
- ✦Runs entirely in your browser. Nothing you enter is ever uploaded

- ✦Works offline once the page has loaded
See it in action
A cafe owner wants a QR code on table cards that opens the digital menu without an app.
What you type
https://sunnysidecafe.example/menu
What you get
A crisp black-on-white QR code renders instantly in the browser (nothing uploaded to a server). Point any phone camera at it and the menu link surfaces as a tap-to-open banner. Download as PNG or SVG — the SVG stays razor-sharp when scaled up to A5 table cards or an A1 window poster.
Tip: Keep the destination URL short and add generous white space (the 'quiet zone') around the printed code — cramming a long link or trimming the border is the main reason a code scans slowly or fails at a distance.
Use cases
What people use it for
Put your café menu link on table cards so diners open it without typing anything.
Give gig or fundraiser posters a scannable code that jumps straight to the ticket page.
Share your portfolio or LinkedIn from a business card without cramming a long address onto it.
Who uses QR Code Generator?
Cafe owners
printing a code that opens their menu, generated on their own device so no link-shortener sees the traffic
Event hosts
putting a code on invitations that links to directions or an RSVP form with no tracking in between
Privacy-minded users
encoding a wifi password or contact card into a code that is built locally and never uploaded
How it works
- 1Paste a link or type the text you want the QR code to hold.
- 2Your browser builds the code locally with a standard QR algorithm. Nothing is uploaded.
- 3Download the PNG or screenshot it; the code never touches a server.
Tips for the best results
- Point the code at a stable web address you control, so you can change the destination later without reprinting the code.
- Test the finished code with a couple of different phones before you print it at scale.
- Keep a quiet margin of blank space around the code and avoid busy backgrounds, so cameras lock on quickly.
- Do not shrink the code too small on print, since the more information it holds, the denser and harder to scan it gets.
- Because the code is generated locally and not stored, download or save the image yourself before you close the tab.
FAQ
Frequently asked questions
Is this an AI tool, and does my link get uploaded anywhere?
Neither. The code is produced by a standard algorithm running entirely in your browser, the link or text you enter never leaves your device and never touches a server, ours included. That's deliberate: a QR code is deterministic, so there's nothing an AI could add except a privacy risk. Once the page has loaded, generation even works with your connection off.
Will the code scan on any phone?
Codes follow the standard QR format that every modern phone camera and scanner app reads natively, nothing proprietary. Scanning reliability depends more on how you use the code: keep strong contrast against the background, leave a clear margin around it, and don't print it too small for the distance people will scan from. A poster code needs to be far bigger than a business card one.
Does the code expire or stop working after a while?
Never. Your text is encoded directly into the pattern itself, with no redirect service or server sitting in between, so there's nothing to expire, no scan tracking, and no subscription that lapses and kills your printed codes, a real risk with commercial 'dynamic QR' services. The only way it stops working is if the page it points to goes offline.
What happens if I move the page the code points to?
The code stores the URL literally, so it keeps sending people to the old address. You can change what's on the page freely (a menu behind the same link can update daily) but if the address itself changes, you need to generate and reprint a new code. If you expect the destination to move, encode a short URL you control and redirect from there.
How much text can I put into one code?
Quite a lot, but there's a practical trade-off: the more characters you encode, the denser the pattern becomes, and dense codes are harder to scan from a distance or at small print sizes. For anything beyond a short link or a few lines of text, put the content on a page and encode the link instead, the code stays clean and scannable.
Can I make the QR code bigger for a poster?
Yes. A QR code is made of squares, so it scales to any size without going blurry. Generate it here and enlarge it in whatever you are designing, from a business card to a shopfront banner. Keep a clear margin of blank space around it so scanners can read it.
Can I generate QR codes in bulk without an account?
This tool makes one code at a time, and needs no account to do it. Because each code is built right in your browser, you can generate as many as you like, one after another, at no cost. For a batch, just repeat the process with each link or piece of text.
Can a QR code store contact details or wifi login?
Yes. Beyond a web link, a code can hold plain text, contact details, or wifi network details so a guest can join without typing a password. Enter the information and it is encoded locally on your device. Nothing you put in is sent anywhere or saved by the site.
Are there any usage limits?
None. Everything is generated locally in your browser, so there is no server cost, no metering, and no daily cap, use it as many times as you like, completely free.
