Static and independent
A static QR code has no built-in expiration. A URL QR still works only while its destination remains available.

Create a static QR code
Enter the information, choose a reliable style, and download a static QR code that works independently of CoreBase.
Strong color contrast for reliable scanning.

Static QR codes
The destination is stored directly in the code.
A static QR code contains the exact URL, text, contact action, message, or Wi-Fi settings you provide. It does not use a CoreBase short link or redirect, so the downloaded code does not depend on this website.
PNG or SVG
PNG is convenient for screens and documents. SVG is a true vector and stays sharp when resized for print.
Contrast matters
Dark modules on a light background are the most reliable. Low contrast, large logos, blur, or poor printing can prevent scanning.
Error correction
L, M, Q, and H add increasing recovery capacity. A centered logo uses H automatically because it covers part of the code.
Logo safety
The logo is limited to a small central area and surrounded by clear space. Always test the final file in its real context.
Wi-Fi QR content
A Wi-Fi QR stores the network name, security type, password, and hidden-network setting. Anyone who scans it may see or use those credentials.
Frequently asked questions
QR Code Generator FAQ
What is a QR code?
A QR code is a two-dimensional barcode that stores data in a pattern a compatible camera or scanner can read.
Do CoreBase QR codes expire?
No expiration is added to a static QR code. If it contains a URL, that URL must remain available for the code to stay useful.
Will it work if CoreBase is unavailable?
Yes. The selected content is embedded directly in the downloaded code, with no CoreBase redirect or hosted lookup.
What is the difference between static and dynamic QR codes?
Static codes contain their destination directly. Dynamic services usually encode a managed redirect that can be changed but depends on the provider.
Which download size should I choose?
Use 500 or 1000 px for most digital uses, 2000 or 3000 px for larger raster output, and SVG when you need flexible print scaling.
Can I add a logo?
Yes, but a logo removes readable modules. This tool limits its size and uses high error correction; you should still test the downloaded result.
Is local verification a guarantee?
No. It confirms that the generated preview can be decoded locally. Camera quality, print size, glare, damage, and viewing distance can still affect scanning.
Is my information sent to CoreBase?
No. Generation, image handling, verification, and export run in your browser. The tool does not submit QR content to CoreBase.
Sources and methodology
How this generator creates and checks a QR code.
CoreBase encodes the selected content locally using standards-based QR encoding with a four-module quiet zone. The same matrix, colors, style, logo, and error-correction setting drive the preview and downloads. The rendered preview is decoded locally and marked verified only when the decoded value exactly matches the source payload.
Accuracy & trust
Built to be useful. Designed to be checked.
We test and review CoreBase tools, formulas, and information to keep them useful and accurate. Occasional inaccuracies or circumstances specific to your situation can still affect a result, so verify important decisions against your own requirements.
