What this QR code generator does
QR Code Generator turns a link or plain text into a scannable QR code directly in your browser. It is useful for posters, restaurant menus, classroom pages, product labels, event signs, printed instructions, and quick sharing when typing a long link would be annoying.
You can adjust the foreground and background colors, add an optional center logo, set the quiet zone around the code, and download the final result as PNG or SVG. PNG is convenient for messages and quick uploads, while SVG is sharper for print, signs, and design files because it scales without becoming blurry.
How to use it
Paste the link or text you want to encode, check the preview, then download the format you need. If you add a logo, use the strongest error correction option and keep the logo small enough that the QR pattern is still easy to scan.
Useful details
QR codes need contrast. Dark foreground on a light background is the safest choice. Colored QR codes can work well, but very pale foreground colors, transparent-looking backgrounds, or low contrast combinations can scan poorly. The quiet zone also matters: leave clear space around the QR code when printing or placing it in a design.
Privacy
The QR code is generated on your device. The text you enter and any logo image you choose are not uploaded by this page. If you download a QR code, the downloaded file is created in your browser.
Limitations
Very long text creates dense QR codes that may scan slowly or fail on small prints. Some camera apps also handle unusual colors, glossy paper, and small display sizes differently. Always test important QR codes with a phone before printing many copies.
FAQs
Can I add a logo to the QR code?
Yes. Choose a logo image and keep it modest in size. The tool recommends stronger error correction when a logo is used because the logo covers part of the QR pattern.
Should I download PNG or SVG?
Use PNG for quick sharing or simple uploads. Use SVG when you need a crisp QR code for print, large signs, or design software.
Why does contrast matter?
QR scanners need to separate dark modules from the background. Low contrast colors can look nice but scan poorly, especially in print or low light.
Can I use this for Wi-Fi or WhatsApp QR codes?
This first version supports URL and text QR codes. Dedicated Wi-Fi, WhatsApp, and contact QR tools can be added later with guided fields for those formats.
