Turn any link, text, email or phone number into a custom QR code. Choose the size, colours and error-correction level, watch the preview update as you type, then download a crisp, high-resolution PNG. No signup, and everything runs right in your browser.
The QR Code Generator builds a scannable QR code from whatever you paste into the box — a website link, a line of text, an email address or a phone number. You control the finished image: pick a pixel size for the export, set the foreground and background colours, and choose how much error correction to bake in. The preview redraws instantly, so the code you see is exactly the one you download. The image is drawn in your browser using the canvas element, so nothing you type is sent to us or stored anywhere.

Paste a full link like https://yoursite.com, or type any text, email or phone number.
Set the size, tweak the two colours, and pick an error-correction level to match where it will be used.
Click Download PNG to save the image, then drop it into your design, print job or slide.
The QR code redraws the moment you change the text, size or colours — no "generate" button to press.
Match your brand with any foreground and background colour, and export from 200px up to 800px.
Four levels let you trade a little density for codes that still scan when scuffed or partly covered.
The code is generated locally in your browser. Your links and text never touch a server.
Link a table tent to your digital menu so guests scan and browse on their own phones.
Add a code that opens your website or LinkedIn so new contacts save your details in one tap.
Point buyers to setup guides, warranty registration or a how-to video from the box.
Turn a wall or handout into a tap-through to event tickets, a signup form or a landing page.
Encode a phone number or short instructions so people connect or reach you without typing.
Link shelf tags and window displays to reviews, offers or the exact product page online.
A QR code — short for "Quick Response" code — is a square, two-dimensional barcode that a phone camera can read in an instant. It was invented in 1994 by the Japanese company Denso Wave to track parts on car assembly lines, where an ordinary striped barcode simply could not hold enough information. Because a QR code stores data across a grid of black and white squares rather than a single row of lines, it packs far more in and can be scanned from any angle.
That capacity is why QR codes are now everywhere: a single code can hold a web address, a paragraph of text, contact details or payment information. Modern iPhones and Android phones read them straight from the built-in camera app, with no separate scanner to install — which is what turned QR codes from a factory tool into an everyday bridge between print and the web.
Every QR code is a grid of small squares called modules, and their black-or-white pattern is simply your data written in binary. A few parts of that grid are always reserved so a camera can lock onto the code quickly and correctly:
When you point a camera at the code, it locates the three corner squares, straightens the image, reads the module grid back into binary, uses the error-correction data to fix any misreads, and finally decodes the result — usually opening a link or showing text. All of that happens in a fraction of a second, which is exactly where the "quick response" name comes from.
A QR code is just text, so you can encode almost anything short. The trick is knowing the little prefix that tells a phone how to treat what it reads. Paste any of these into the box above:
https:// so it opens as a tappable link.mailto:you@example.com to open a new email addressed to you.tel:+15551234567 so scanning starts a call to that number.sms:+15551234567 opens the messaging app ready to text you.geo:37.7749,-122.4194 drops a pin in the phone's maps app.For anything you want people to act on, keep it short. A tidy link scans faster and more reliably than a long one stuffed with tracking parameters, so shorten the URL before you encode it where you can.
Error correction is what lets a QR code survive a scratch, a coffee ring or a logo dropped on top of it. It works by storing redundant copies of your data, so a reader can rebuild the parts it cannot see. You choose how much redundancy to add, and there are four standard levels:
There is a trade-off. Higher correction adds more modules, so the pattern gets denser and needs to be printed a little larger to stay readable. If a code will live somewhere clean and be scanned up close, M is plenty. If it will be printed small, handled a lot, or partly covered, step up to Q or H.
A QR code only earns its keep if people can actually scan it. These habits keep your codes readable in the real world:
Yes. QR code is an open standard with no licence fee or royalty, and every code you create here is completely free to use for personal or commercial projects. There is no signup, no watermark and no limit on how many you make.
No. This tool makes static QR codes, which means your link or text is written directly into the pattern. The code will keep working for as long as the destination it points to exists — it does not run through any redirect service that could be switched off. Only the page or number you encoded can stop working, not the code itself.
No. The QR code is drawn entirely in your browser using the canvas element. Whatever you type stays on your device and is never sent to ToolBrainy or any third party, which makes the tool safe for internal links, contact details and private notes.
Choose the Large (500px) or Extra large (800px) option for anything that will be printed. A bigger PNG stays crisp when it is scaled up in a design tool or sent to a printer, while the 200px size is best kept for on-screen use.
Yes. Set any foreground and background colour with the two pickers. Just keep good contrast — a dark code on a light background scans most reliably. Very light colours or two similar tones can stop the code from reading.
The usual causes are weak contrast, a code printed too small, no quiet zone around it, or too much data crammed in. Increase the size, keep dark-on-light colours, leave a clear margin, and shorten the link. Raising the error-correction level to Q or H also helps in rough conditions.
At the largest version a QR code can store roughly 7,000 digits, 4,300 letters and numbers, or about 2,900 bytes of data. In practice you should stay far below that — the more you encode, the denser and harder to scan the code becomes, so short links and brief text always work best.
This tool exports a clean code without a logo, but QR codes tolerate a small central image because of error correction. If you plan to place a logo over the middle in a design tool, generate the code at the High (H) error-correction level first so it still scans with part of the pattern covered.
A static code, like the ones here, contains your data directly and cannot be changed once printed. A dynamic code instead points to a short redirect URL that an external service can re-route later, letting you edit the destination or track scans — usually for a monthly fee. Static codes are free, private and permanent; dynamic codes trade that for editability.
Almost all of them. iPhones running iOS 11 or later and modern Android phones read QR codes straight from the native camera app — just point and tap the link that appears. No separate scanner app is needed on current devices.
