Decode and read embedded data out of QR code images.
Quick Response (QR) codes offer a seamless optical bridge connecting physical touchpoints to digital content. The QR Decoder creates high-density, crisp 2D barcodes optimized for instant camera recognition across iOS and Android smartphones, handheld scanners, and industrial readers.
Customize your QR code with flexible error correction levels (Low, Medium, Quartile, High) to guarantee scannability even when printed on textured materials, curved packaging, or partially obstructed surfaces.
| Specification | Supported Formats / Standards | Standard Reference | Technical Profile |
|---|---|---|---|
| Barcode Matrix | ISO/IEC 18004 Standard | 2D QR Matrix Format | Micro QR and Standard Model 2 QR matrices |
| Error Correction | Levels L (7%), M (15%), Q (25%), H (30%) | Reed-Solomon Codes | Recovers scannability even when partially smudged |
| Export Formats | PNG (Raster), SVG (Vector Scalable) | image/png, image/svg+xml | High-DPI commercial printing and mobile scanning |
| Encoding Capacity | Alphanumeric, Byte, Numeric, Kanji | Up to 7,089 numeric chars | Accepts URLs, contact vCards, Wi-Fi strings, plain text |
Yes. All QR codes created with the QR Decoder are 100% free for both personal and commercial use on product packaging, flyers, menus, and websites.
No. Our QR codes are static, meaning the data is encoded directly into the barcode matrix. They will continue to work indefinitely without monthly fees.
For standard printing on smooth paper or screens, Level M (15%) is ideal. If printing on rough textures, outdoor banners, or placing a small logo in the center, choose Level H (30%) for maximum scan reliability.
We recommend downloading the vector SVG format for commercial printing, billboards, and laser engraving, as SVG scales infinitely without pixelation.
