How much data does it support?

We support URLs and text up to several thousand characters. However, the larger the amount of data, the more complex the QR code pattern becomes and may be difficult to read.

This tool only supports color customization. It does not support inserting a logo image in the center, but it is possible to generate it with the 'error correction level' set to high (H) and place the logo in the center using image editing software.

Can I use it for commercial purposes?

Yes. The QR code images generated by this tool can be freely used for commercial purposes (printing on flyers and business cards, etc.) by both individuals and corporations.

Glossary

QR Code (Quick Response Code): A two-dimensional matrix barcode invented in 1994 by Denso Wave. Designed for high-speed component scanning, it now bridges the physical world with digital URLs.
Error Correction Level: A built-in fallback system using Reed-Solomon algorithms. Allows a QR code to be readable even if dirty or damaged. Available in 4 levels: L (7%), M (15%), Q (25%), and H (30% restoration capability).
Finder Patterns: The three prominent square structures at the corners of a QR code. They allow the scanner to instantly calculate the code's orientation and size regardless of camera angle.
SVG Format: A Vector graphic format that can be scaled infinitely without any pixelation or quality loss. Highly recommended when exporting the code to use in Adobe Illustrator or commercial printing.
Margin (Quiet Zone): The mandatory blank area surrounding the matrix. Scanners rely on this contrast buffer to isolate the code from the surrounding physical environment or design.
Transparent PNG: An image export mode where the white background is stripped out, leaving only the black (or colored) blocks. Great for embedding directly into existing branded documents.
vCard: An electronic business card standard format. By selecting the vCard generation option, the output QR code will prompt mobile phones to automatically instantly save your contact details to their address book.

faq,

FAQ

Q.Is it completely free for continuous commercial distribution?: Absolutely. The QR codes you generate here contain no trackers, hidden limits, or subscription paywalls. You can print millions of them to sell without attribution.
Q.Will these QR codes ever "expire" or stop working?: No. These are "Static" QR codes. The direct data (URL or Text) is permanently hardcoded into the mathematical pattern mechanism. They will last infinitely forever as long as your destination URL functions.
Q.Why did the pattern suddenly get overwhelmingly dense?: Data capacity rules dictate that the more text or longer URLs inserted into it, the denser the grid matrix becomes. Try utilizing short URLs when printing physically on small labels.
Q.Can I invert the colors or pick custom branding?: You can select custom colors. However, scanning physics dictate that the "dots" must absolutely be darker than the background. Failing this contrast rule renders codes un-scannable on many devices.
Q.How can I insert my company brand/logo perfectly in the center?: Select Error Correction Level "H" (30%), download as structural SVG, and comfortably use external vector apps to overlay an opaque logo on the center space since 30% damage is algorithmically ignored.
Q.Are you compiling history tracking data when scanned?: We embed absolutely zero tracking pixels. Because they are static, any analytics measurement requires you to explicitly add Google UTM parameters to your URL string before generating.
Q.Does it work offline without Wi-Fi?: Yes. Since our architecture relies on lightweight JavaScript logic running strictly inside your loaded browser window, no connections to encoding servers are ever made or requested natively.
