Free QR Code Generator

Yes, our QR code generator is 100% free to use. You can create unlimited QR codes with no restrictions on usage. We don't charge for downloads or impose any watermarks on your generated QR codes.

Adding a logo can affect scanability if it's too large. We recommend keeping logos under 30% of the QR code size and using high error correction (H) when adding logos to ensure your QR code remains scannable.

Yes, the QR codes you generate are static and will work indefinitely as long as the information they contain remains valid. For example, a URL QR code will work as long as that URL remains active. We don't provide dynamic QR codes that can be edited after creation.

PNG is a lossless raster format ideal for digital use and small to medium prints. SVG is a vector format that scales infinitely without quality loss, perfect for large prints. JPG is a compressed format suitable for photographs but may reduce quality for QR codes. WebP offers good compression with quality preservation, ideal for web use.

Yes, your data is completely secure. All QR code generation happens locally in your browser, which means your information never leaves your device or gets sent to our servers. We don't store any of the data you enter into the generator.

Error correction allows QR codes to remain scannable even if part of the code is damaged or obscured. Higher error correction levels make the QR code more resilient but also increase its size. For most purposes, the medium (15%) error correction level works best, but we recommend high (30%) when adding logos.
