How to use the QR Code Generator
- Choose what the QR code is for. The input label changes to match: a link, a YouTube video, a Facebook page, an Instagram username, or a WhatsApp number.
- Type or paste the content. For WhatsApp, enter the number with its country code (for example 919876543210) and an optional pre-filled message.
- Pick a size and, if you like, the colours. Keep a dark QR colour on a light background for the best scanning.
- Press Generate QR code, then Download PNG.
QR code tips
- Test every QR code with a phone before printing it.
- Leave the white border around the code. It helps scanners find the code.
- For print, choose the larger sizes. A rough guide is that the code should be about one-tenth of the scanning distance, so a code scanned from 1 metre should be about 10 cm wide.
- Shorter content makes a simpler code that scans faster and from further away.
Ideas for using QR codes
- Business cards and brochures: link to your website or WhatsApp chat.
- Menus and price lists: link to an online page so you can update it without reprinting.
- Events and posters: send people straight to a registration or information page.
- Social profiles: make it easy to follow a page or profile in one scan.
Common mistakes to avoid
- Printing too small. A code that is too small for the scanning distance will not read.
- Low contrast. Light colours on a light background, or a colour QR on a busy picture, make scanning unreliable.
- Not testing. Scan the final printed or on-screen code with at least two phones before sharing.
- Encoding a long link. Longer content makes a denser code. Use a short link when you can.
Frequently asked questions
Is the QR code free to use commercially?
Yes. The QR codes you create here are yours to use on websites, posters, packaging and business cards. Test them before you print.
Does the QR code expire?
No. These are static QR codes: the content is stored inside the pattern itself, so they never expire and do not depend on this website.
Is my text uploaded anywhere?
No. The QR code is generated in your browser and the content is not sent to a server.
Can I add a logo to the QR code?
This tool does not add logos. If you add one in an image editor, keep it small and test the code, because a large logo can stop it scanning.
Why does my QR code not scan?
Common reasons are low contrast between the colours, a missing white border, a printed size that is too small, or too much text. Use dark on light, keep the border, and print larger.
What sizes can I download?
128, 256, 512 or 1024 pixels square as a PNG image. Use the 512 or 1024 size for anything you will print.
How much text can I put in a QR code?
A QR code can hold a lot, but longer content makes a denser pattern that is harder to scan. This tool accepts up to 1,000 characters, and shorter is better.
Do I need an app to scan a QR code?
Most modern phone cameras can scan QR codes directly. If yours cannot, a free QR scanner app will work.
