- Use darker foreground colors and a light background for better scanning reliability.
- Higher error correction improves resilience but makes the pattern denser.
- Use SVG for business cards, keep the printed QR at least 0.8 in / 20 mm wide, preserve quiet zone, and test scan before printing.
Quick answers
How to make a Wi-Fi QR code
Type the network name (SSID) and password, pick the security type, and download. Guests scan the QR and their phone connects automatically, no password to type.
How to do it
Switch to the Wi-Fi tab, enter the SSID and password, select WPA/WEP/None, and download. The QR encodes the WIFI: scheme that phones read natively.
Why use this tool
Your network credentials stay on your device. The QR is generated locally; no server ever sees your SSID or password.
Hidden networks
If your network is hidden (does not broadcast its SSID), check the "Hidden network" box. The QR will include the H:true flag so the phone knows to connect even though the network is not visible.
Security types
WPA/WPA2/WPA3 is the most common and recommended. WEP is legacy and rarely used. "None" creates an open network QR with no password needed to connect.

About Wi-Fi QR codes
A Wi-Fi QR code uses the WIFI: URI scheme defined in the ZXing barcode library. When a phone scans it, the OS reads the network name, password, and security type, then connects automatically with no manual entry needed.
This is especially useful for cafés, Airbnbs, offices, and events where you want guests to connect without asking for the password or typing it wrong. Print the QR on a table tent, a poster, or the back of a business card.
Special characters in the SSID or password (backslashes, semicolons, colons, commas, double quotes) are automatically escaped in the QR payload so the phone reads them correctly.

Export PNG or SVG instantly, copy the QR image where supported, and test scan before printing.
Privacy and quality
Your data never leaves your device. The QR code is generated and rendered entirely in the browser, with no server, no upload, and no tracking.
No account, no sign-up, no watermark. Open the page, type your content, and download a clean PNG or SVG.
Works offline once loaded. After the first visit, the page runs without a network connection because all the logic is in JavaScript.
FAQ
Common questions
Does this upload my content anywhere?
No. QR payloads are generated in the browser using a client-side library and rendered on the page locally.
Which export should I choose?
SVG is best for print and scaling. PNG is easier for quick sharing in slides, docs, chats, and social posts.
Why did my QR stop rendering?
Very long content can exceed QR capacity. Shorten the text or lower the error correction level to fit more data.
What does error correction do?
Error correction adds backup data so the QR can still be read even when partly covered, damaged, or printed on a rough surface. Higher levels (Q, H) tolerate more damage but make the pattern denser. Medium (M) is a good default for most uses.
