Frequently Asked Questions
Is my CSV data uploaded or stored on any server?
No. All CSV parsing, QR rendering, and ZIP archiving take place locally inside your web browser. No data is transmitted to external servers or remote databases.
How do I convert a CSV file to a ZIP download of QR codes?
Select the Upload CSV File tab, choose your spreadsheet, customize your preferred shapes, colors, or center logos, and click Generate & Download ZIP. Each row in your CSV is converted into an individually named file.
What is the difference between PNG, SVG, and EPS outputs?
PNG is a raster format suitable for digital display, websites, and office printing. SVG and EPS are scalable vector formats that use mathematical paths, maintaining crisp lines without pixelation regardless of how large they are printed.
Can I customize body patterns, gradients, and logo overlays?
Yes. You can select custom dot patterns (dots, rounded, classy), corner eye designs, linear gradients, background hues, and upload center brand logos. High Error Correction (30%) is automatically recommended when logos are embedded.
Do static QR codes generated in bulk ever expire?
No. Static QR codes encode payload information directly into the matrix geometry. They remain permanently functional without requiring external redirect servers or recurring fees.
