QR Code Generator & Reader
QR Code Generator & Decoder is a free online tool that creates QR codes from URLs, text, or contact info, and also reads uploaded QR images to extract their content. Customize size, foreground/background colors, and error-correction level for print or screen use.
Both generation and decoding run locally in your browser — nothing is uploaded. No registration, and generated codes never expire with no scan limits.
How to Use
- Choose Generate or Decode mode
- Generate: enter a URL or text, then set size, colors, and error correction
- Decode: upload or drop a QR image to read its content automatically
- Download the QR image, or copy the decoded result
FAQ
Do generated QR codes expire?
No. These are static QR codes — the content is encoded in the image itself, so they work forever with unlimited scans.
Is my content uploaded to a server?
No. Generation and decoding both happen locally in your browser.
Can I customize colors and size?
Yes. Size, foreground and background colors, and error-correction level are all adjustable.
What is error correction and which level should I pick?
It determines how much damage or occlusion a code tolerates while remaining scannable. Choose high (H) for print or logo overlays; medium/low is fine for on-screen use.
