Do these QR codes expire?

No. The code holds your link or text itself, drawn as a pattern, rather than pointing at a redirect on our servers. It works for as long as what it holds is true: a link keeps working while the page exists. There is nothing to renew and nothing that tracks who scans it.

How does the Wi-Fi code work?

It holds your network's name, password and security type in the standard format phone cameras understand. Pointing an iPhone or Android camera at it offers to join the network, with no typing. Enter the name exactly as your phone lists it, capitals included.

Should I download PNG, SVG or PDF?

PNG is an ordinary picture, right for messages, documents, slides and the web. SVG is a vector file that stays perfectly sharp at any size, which is what a design app wants for posters and packaging. PDF is the one to print yourself: it is vector too, laid out on A4 or US Letter with the code at the width you choose — print it at 100% (actual size) — or as just the code, to place into another document.

How big should a printed QR code be?

At least 2 cm across for something held in the hand, such as a business card, and larger the further away people will scan it from: roughly a tenth of the scanning distance, so 5 cm on a table menu and 12 cm or more on a poster across a room. A long link makes a denser code, which needs more room; the page warns you if the squares would print too small to scan reliably.

Can I change the colours?

Yes, under Advanced options. Keep the code dark and the background light, with strong contrast between them: the page warns you if the colours you pick are likely to fail on some phones.

What is error correction?

Extra data that lets a code scan even when part of it is scuffed, dirty or covered. Medium suits almost everything. High survives the most damage, which helps on printed codes that get handled, at the cost of a denser pattern.

Yes. There is no account to create, no watermark on what you download and no limit on how many you make.

Is what I type sent to your servers?

No. This tool works entirely in your browser: the file is made on this page, nothing is uploaded, and nothing you type is stored by us. Most tools on ConvertNicely do their work on our servers; this one does not need to.

Does it work on a phone?

Yes. The whole site is built mobile-first, so you can make the file on your phone and download it, or show it on screen.

Create a QR Code

Turn a link into something a phone camera can open, or let guests join your Wi-Fi without spelling out the password. Type what the code should hold and it appears as you type, ready to download as a PNG, an SVG or a PDF that prints it at the size you choose. It is made on this page: nothing you enter is uploaded, and the code holds your text directly, so it never expires and nothing tracks who scans it.

PNG is 1024 × 1024 px. Scan the code with your phone before you print it.

What it holds

Link or text

A web address opens in the phone's browser; anything else is shown as text.

PNG size

The SVG and PDF downloads stay sharp at any size.

PDF page

PDF print size

The width of the code itself. A margin four squares wide, in the background colour, is added around it.

Advanced options

Error correction

How much of the code can be scuffed or covered and still scan. Higher makes the code denser.

Code colour

#000000

Keep it dark: scanners look for dark squares on a light background.

Background colour

How to create a QR code

Step 1
1. Type what the code should hold
Paste a link or type some text, or choose Wi-Fi network and enter its name and password. The code redraws as you type, and nothing you enter leaves your browser.
Step 2
2. Choose your settings
Fill in “Link or text”. Adjust What it holds (Link or text), PNG size (1024 × 1024 px), PDF page (A4) and PDF print size (5 cm), or keep the starting values in brackets, which suit most files. Some choices show further settings. More are under Advanced options.
Step 3
3. Download it as PNG, SVG or PDF
PNG for sharing, documents and slides; SVG for design apps; PDF to print straight away, at the size you chose. Scan it with your phone before you print it.

Worth knowing

Scan the code with your phone before you print it. Scanners look for dark squares on a light background, so a light code on dark, or two similar colours, will fail on many phones. The more text a code holds the denser it gets, so a long text needs a bigger print to scan reliably.

Why create a QR code?

Putting a link to a menu, form or website on a poster or flyer
Letting guests join your Wi-Fi without reading out the password
Adding a scannable link to slides, packaging or a business card
Sharing a long address that is awkward to type on a phone
