QR Code Generator

About this tool

Make a QR code for a link, a Wi-Fi network, an email, a phone number or a text message. Scan it with a phone camera to open the link or join the network. Download it as a PNG for documents and slides, or as an SVG that stays sharp at any size when printed.

Everything runs in your browser. What you type, including a Wi-Fi password, is never sent to a server.

How it works

• Text is encoded as UTF-8, so non-English characters scan correctly. The code is a static QR code: the data is stored in the image itself, so it never expires and nothing is tracked.
• Error correction lets a code still scan when part of it is dirty or covered. Higher levels (Q, H) survive more damage but make the code denser. L or M is best for screens and clean prints; use Q or H if you put a logo over the center.
• Image size is a target. The modules (the small squares) are drawn as whole pixels so the edges stay sharp, so the downloaded PNG can be a few pixels smaller than the size you chose. The SVG has no pixel limit.
• Quiet zone is the blank border around the code. Scanners need about 4 modules of it. Reducing it saves space but can make scanning fail.
• Colors: scanners expect a dark code on a light background. The tool warns you when the contrast is low or the colors are inverted, and many apps cannot read inverted codes.
• Capacity: up to 2,953 bytes at level L, and fewer at higher levels. The more you store, the denser and harder to scan the code becomes. For long URLs, a short link works better.
• Wi-Fi codes use the standard WIFI:T:WPA;S:name;P:password;; format that current Android and iOS cameras understand. Special characters in the name or password are escaped for you.
