Free QR Code Generator

This free QR code generator turns a link, plain text, a WhatsApp number, or Wi-Fi details into a QR code in seconds. Pick the content type, type your data, and the code appears in the preview, ready to download as PNG or SVG. You can make as many QR codes as you like without signing up, and every code is created in your browser, so its content is never sent to a Dokurapi server.

Static and dynamic QR codes

The codes made here are static QR codes: the content is stored in the pattern itself. There is no redirect link in between, so a code keeps working for as long as its content does, for example as long as the page it points to is online. The trade-off is that a static code cannot be changed once printed. If your link changes, make and print a new code.

Dynamic QR codes point to a short link run by a service, which lets the owner change the destination and count scans. Because they depend on that service, they can stop working if the service shuts down or a subscription lapses. Dokurapi does not offer dynamic QR codes yet. If you need them, tell us through the WhatsApp link in the tool.

What you can put in a QR code

The Wi-Fi format follows the one documented by the ZXing project. Recent Android and iPhone cameras can usually join the network straight from the code. Remember that the password is stored as plain text inside the code, so anyone who scans it can read it. Use it for guest networks only.

Size, colour, and error correction

Choose a PNG size from 256 to 2048 pixels. For large prints such as banners or stickers, download the SVG, which stays sharp at any size. Every code keeps a blank border of at least four modules, as the QR standard requires, so cameras can find it easily.

Error correction sets how much of the code can be damaged or covered while it still scans: L about 7%, M 15%, Q 25%, and H 30%. Higher levels make the pattern denser. M suits most uses, while H helps for stickers that get scratched. You can change the colours too, but keep a dark code on a light background with strong contrast. The tool warns you when the colours are too pale or inverted.

Content limits and printing tips

One QR code holds at most 2,953 bytes at the largest version with level L, according to the DENSO WAVE standards page. The longer the content, the denser the pattern and the harder it is to scan from a distance, so prefer short links. Before printing a batch, scan the code with two different phones from the real viewing distance. QR Code is a registered trademark of DENSO WAVE INCORPORATED.
