What image formats does the QR decoder support?

PNG, JPG/JPEG, and WebP images are supported. The QR code should be clearly visible and not blurry.

Are my images uploaded to a server?

No. All decoding happens locally in your browser. Your images never leave your device.

What types of QR codes can be decoded?

Any standard QR code including URLs, plain text, WiFi credentials, vCards, email, phone numbers, and SMS.

Why wasn't my QR code detected?

Ensure the image is well-lit, in focus, and the QR code fills a reasonable portion of the image. Heavily distorted or damaged codes may not decode reliably.

QR Code Decoder Frequently Asked Questions

What image formats are supported?

PNG, JPG, and WebP. The QR code must be clearly visible and not too small or blurry.

Does this upload my image anywhere?

No. Decoding is done entirely in your browser. Your images never leave your device.

My QR code wasn't detected - why?

Try a higher-resolution image where the QR code fills more of the frame. Very small or heavily damaged codes may not decode.

2D QR Matrix Standards & Printing Guidelines

Quick Response (QR) codes are two-dimensional matrix symbologies standardized under ISO/IEC 18004. Equipped with Reed-Solomon error correction (ranging from Level L at 7% recovery up to Level H at 30% recovery), QR codes allow reliable scanning even if portions of the printed matrix suffer physical abrasion, smudging, or partial obstruction by custom logos.

Quiet Zone & Contrast Ratios

Always preserve a quiet zone border of at least 4 modules around the outer edge of the QR code. Avoid low-contrast color combinations (such as yellow on white); dark modules on light backgrounds deliver the fastest camera decode speeds.

Vector Print & Privacy Security

Export your finished code in SVG vector format for crisp, infinite scalability on large signage, product packaging, and business cards without pixelation. All generation and camera decoding executes 100% locally in your browser memory-no private credentials, URLs, or scans are ever uploaded to a server.

Additional Technical FAQs

What is the minimum recommended print size for reliable scanning?

For standard smartphone camera scanning at close range (0.3–0.5 meters), print QR codes at a minimum size of 2 x 2 cm (0.8 x 0.8 inches). For posters and billboards, use a 10:1 distance-to-size ratio (e.g., a code scanned from 2 meters away should be at least 20 cm wide).

Are generated codes permanent, and do they ever expire?

All codes generated on BeYourTools are static and permanent. The encoded data (such as your URL, text, or barcode number) is directly baked into the graphical modules with zero server redirection, meaning they will function forever without expiration.
