FAQ
What is a QR code?
A QR code (Quick Response code) is a type of barcode that stores information in a square grid. When scanned, it can instantly open a website, show text, share contact details, or connect to Wi-Fi without typing anything manually.
How does a QR code work
A QR code works by converting data into black and white patterns. Your phone’s camera or a QR scanner reads these patterns and quickly translates them into useful information like a link or message.
What information can a QR code store
QR codes can hold different kinds of information such as website URLs, phone numbers, email addresses, payment links, app downloads, or even event details. Advanced QR codes can also store Wi-Fi login credentials and vCards.
How do I create a QR code?
To create a QR code, use our online QR code generator https://www.onlineqrcode.in/. Enter the data you want to share, choose the style and size, and download the code in PNG or SVG format.
How do I scan a QR code?
Static QR codes never expire, but the link may stop working if the original website is removed. Dynamic QR codes can be set to expire, or the owner can update or disable them at any time.
Are QR codes safe to use?
QR codes themselves are safe, but they can direct you to unsafe websites. Always scan codes from trusted sources and check the URL before clicking any links.
Is anything I type sent to a server?
No. All QR code generation happens locally in your browser using open-source libraries. We do not transmit or store your data.
Can I generate a QR code offline?
Yes. After the page loads once (PWA ready), previously cached assets can allow offline generation for basic text/URLs.
What formats can I download?
You can download PNG (bitmap) and SVG (infinite scaling). Choose SVG for print-quality or large-format uses.
What is error correction (L / M / Q / H)?
Error correction adds redundancy so the code still scans if partially damaged or covered. Higher levels increase size/density.
Why won’t my long text scan?
Very long or complex content creates dense modules. Try shortening the text, using a URL shortener, or increasing size & lowering error correction.
Can I use these QR codes commercially?
Yes. Generated QR codes are yours. Ensure embedded content complies with applicable laws and platform policies.
