Do static QR codes created on qrqr.fyi ever expire?

No. Static QR codes encode your data (such as a website URL, WiFi credentials, or vCard contact card) directly into the pixel matrix. Because there is no intermediary redirect server involved, static codes function permanently, will never expire, and do not require any recurring subscription or account.

What is the best export format for printing physical signs and flyers?

For commercial printing, posters, banners, and signage, vector SVG (Scalable Vector Graphics) is strongly recommended. Vector files scale infinitely without blur or pixelation. For digital applications, social media, and home inkjet printing, high-resolution 1024x1024 PNG files are ready for immediate use.

How does Reed-Solomon error correction protect QR codes?

Error correction adds mathematical redundancy so cameras can decode the payload even if the physical code is scratched, dirtied, or partially obscured by a logo. Level L recovers up to 7% of damaged data, Level M recovers 15%, Level Q recovers 25%, and Level H recovers up to 30%.

How is the Beta redesign different from the classic generator?

The Beta redesign streamlines the creation workflow into three fast steps. It offers 1-click curated style recipes, real-time contrast checking with a live scannability score, a side-by-side desktop layout, and instant vector SVG and PNG downloads with zero interface clutter.

Can I embed a custom logo without breaking scannability?

Yes. When placing a center mark or logo, select Error Correction Level H (30% recovery) so the matrix retains sufficient redundant data. Ensure your logo does not cover the three corner finder eyes, and verify that the foreground and background colors maintain at least a 7:1 contrast ratio.

When should I upgrade to Dynamic QR codes?

You should upgrade to Dynamic QR codes when you need to update destination URLs after printing (preventing wasted print runs), or when your marketing campaign requires real-time analytics such as scan volume, scanner operating systems, and hourly engagement trends.

The 10:1 Optical Rule

Minimum Width = Scanning Distance divided by 10

For smartphone cameras to focus cleanly without digital zoom artifacts, the physical width of the QR code matrix should measure at least one-tenth of the distance between the scanner and the printed item.

Example Calculation

2.0 m → 20 cm

6.5 ft scanning distance requires a 7.9-inch wide QR code

Practical Print Sizing Reference Table

Physical Medium	Average Scan Distance	Recommended Dimensions	Min. Error Correction

Core QR Vocabulary and Definitions

Quiet Zone: The solid white margin surrounding all four sides of a QR code. It must measure at least four module widths to prevent surrounding text or graphics from interfering with optical camera sensors.
Finder Pattern (Position Detection Eyes): The three concentric square targets positioned in the upper-left, upper-right, and lower-left corners of the matrix. They allow mobile cameras to recognize orientation at any 360-degree angle.
Vector SVG Export: Scalable Vector Graphics XML format that renders paths mathematically rather than as fixed pixel grids. Allows infinite scaling for massive billboards, retail signage, and vehicle wraps without blur.
Luminance Contrast Ratio: The relative brightness difference between dark modules and the light background. Reliable camera scanning requires a minimum 4.5:1 ratio, with 7:1 or higher recommended for printed signage.
