Is this QR code generator really free?

Yes. There is no signup, no watermark and no limit. The code is generated entirely in your browser, so it keeps working without an ExamHall account.

Do these QR codes expire?

No. This makes a static QR code, which stores the content itself. It does not depend on a redirect service, so it will keep working for as long as the destination exists.

Should I download PNG or SVG?

Use PNG for screens, chat and simple documents. Use SVG for printing, signs, certificates and anything that may be resized — vectors stay sharp at every size.

Why is my QR code not scanning?

The usual causes are low contrast, a code printed too small, or a background pattern behind the quiet zone. Keep the code dark on a light background, leave the white margin around it, and test the printed copy with two different phones.

Can I use this for exam scripts or certificates?

Yes. ExamHall itself prints QR codes on answer sheets, but this generator is standalone and free for any personal or commercial use.

Is my content uploaded anywhere?

No. Everything runs locally in your browser. Nothing you type is sent to a server or stored.

How it works

Get your result in a few steps

1
Paste what the code should open
Enter a website address, plain text, a phone number or Wi-Fi details. The preview updates as you type.
2
Pick the error correction level
Medium is right for most uses. Use High when the code will be printed small, photocopied or placed on a busy background.
3
Choose the export size
512 px is fine for screens. Use 2048 px or larger for printing, and SVG when the code will be resized.
4
Download PNG or SVG
PNG is ready for slides, WhatsApp and Word. SVG stays sharp at any size and is the better choice for professional print.
