Batch QR code generator
This tool turns a plain list into a grid of scannable QR codes. Type or paste one note or link per line and a separate QR code appears for each line as you type — no button to press and no waiting. It is built for jobs where you need many codes at once: labelling moving boxes, tagging inventory, printing quiz or scavenger-hunt clues, or handing out a batch of links on a worksheet.
How it works
The input is split on line breaks, each line is trimmed of surrounding spaces,
empty lines are dropped, and the list is capped at the first 50 lines. Every
remaining line is passed to the open-source qrcode library, which renders it as
a 200×200-pixel PNG with a 2-module quiet zone and medium (M) error
correction. The codes are laid out in a responsive grid with the original text
shown beneath each one, plus a PNG download button. All of this runs in your
browser — there is no server round-trip.
Example
Paste these three lines:
Buy milk
Call the dentist
https://example.com
You get three QR codes in a grid. The first scans back to the text
Buy milk, the second to Call the dentist, and the third opens
https://example.com. Clicking the PNG button under the third code saves it as
qr-3.png.
| Lines pasted | Codes shown | Download names |
|---|---|---|
| 1 | 1 | qr-1.png |
| 3 | 3 | qr-1.png … qr-3.png |
| 60 | 50 (first 50) | qr-1.png … qr-50.png |
Your notes and links never leave your device — every code is generated locally.
