How to play
- Type or paste your link or message into the text box — the code builds live as you type.
- Drag the size slider to make the on-screen code bigger or smaller for your display.
- Tap Download PNG to save the code as an image, ready to paste into a slide or worksheet.
- Set how many copies you need and tap Print handout sheet to print a full page for the class.
QR Code Maker turns any link or short message into a scannable code the moment you finish typing, no waiting and no uploading required. Paste a class link, a form, or a quick note, drag the size slider until it looks right, and download the PNG or send a whole sheet of copies to the printer for handouts. Every code is built right there in the browser using a real QR encoder with proper error correction, so it scans cleanly with any phone camera even if a corner gets a little smudged or covered by a sticker. Nothing you type is ever sent anywhere — the text never leaves your device, which makes this a safe pick for student-facing links in a classroom.
Frequently asked questions
- Does the QR code work without an internet connection?
- Yes. The whole code is generated inside your browser using a self-contained encoder — nothing is uploaded, fetched, or sent to a server, so it works exactly the same offline.
- How much text can I fit in one QR code?
- Up to 213 characters of text or a link, which comfortably covers most classroom URLs and short messages while keeping the code easy to scan from a normal printed size.
- Why does the code sometimes look different for the same text?
- The tool automatically tests multiple valid patterns and picks the cleanest-looking one with the least repetition, which can shift slightly as you edit the text — this doesn't affect how reliably it scans.
