QR generation and scanning checks

Create QR codes for URLs, short text, and Wi-Fi details, then decode QR images in the browser before opening or sharing them.

Prepare shareable links

Turn long URLs or Wi-Fi settings into QR images for mobile testing, printed notes, and internal documents.

Inspect QR images

Upload a screenshot or received QR image to see the actual text before opening an unknown link.

Local processing

QR generation and scanning happen in the browser; uploaded images are not sent to a separate server by this tool.

How to use it

Choose whether you are creating a text, URL, or Wi-Fi QR code.

Enter the value that should be scanned and confirm that the QR image renders correctly.

Save the PNG or scan it with another device when you need a final check.

When decoding an image QR, use a sharp source image and inspect the resulting text before opening it.

Real input and output

A link QR code

Input

https://taxijjang.com/json

Output

Scanning opens that address directly

A Wi-Fi QR code

Input

WIFI:T:WPA;S:CafeGuest;P:hello2026;;

Output

Scanning joins the network without typing the password

T is the security type, S the network name, P the password. The two trailing semicolons are required.

Errors you will hit

It scans on screen but not in print

Longer content packs the grid more densely. Shorten long URLs before generating for small print, and keep a quiet zone of at least four modules around the code.

Adding a center logo breaks it

Error correction tolerates some obstruction, but not unlimited. If you plan to overlay a logo, raise the error correction level to H and cover less than 30% of the area.

Things to check

Large payloads scan poorly

The longer the value, the denser the QR code becomes. Shorter links are usually more reliable for small print sizes.

Review Wi-Fi details

Check SSID, encryption type, and password before sharing. Avoid placing sensitive network credentials in public QR codes.
