Frequently Asked Questions

Is UNI-QR really free?

Yes. Every one of the 26 QR types, every design option and every download format is free, with no account, no sign-up, no watermark and no usage limit.

Is my data sent to a server?

No, for every QR type your content is processed locally in your browser and is not uploaded. The one documented exception is the optional "Smart link" setting for App Store/Play codes, which uses a small redirect page on UNI-QR's own site to send iPhone and Android scanners to the right store without storing anything about the scan. See Privacy and Data for the full picture.

Do UNI-QR codes expire?

No. UNI-QR creates static QR codes that store your data directly in the code, so they keep working for as long as the underlying details stay the same. A dynamic QR option, where you could edit the destination later and see scan counts, is previewed on the homepage as a roadmap item and is not available yet.

Which format should I download for printing?

SVG scales to any size without losing quality, which is best for posters or anything printed large. PDF gives you a ready-to-print single A4 page, or a 12-sticker-per-A4 sheet for batches. For a fixed pixel size, PNG or JPEG up to 3000px works well. See Download Formats and Printing for a full comparison.

Can I add my logo and change the colors?

Yes. UNI-QR offers 9 dot styles, 5 corner-frame styles, 4 corner-dot styles, 24 themes, a logo upload, a gradient, a call-to-action frame, a transparent background option and a separate corner color. A logo makes the code denser, so pair a larger logo with a higher error-correction level - see Scan Reliability.

What does the "Scan test passed" badge mean?

After every change, UNI-QR automatically decodes the code it just built and confirms the result still matches what you entered, shown as a green "Scan test passed" badge next to the code's version and module count. It is not a live camera test - always also scan a printed or final code with a real phone before relying on it, especially for payment and WiFi codes.

Does UNI-QR support Urdu, Hindi or other RTL languages?

Yes. UNI-QR is available in 10 languages, including Urdu and Arabic, both of which render fully right-to-left with the whole interface translated, not just individual labels.

Can I create more than one QR code at a time?

Yes, with the separate Bulk QR tool at qr.unisoftware.app/bulk-qr-code-generator: paste up to 50 lines, pick URL, Text, Phone or WhatsApp mode, and download a ZIP of files or a captioned A4 PDF sticker sheet in one pass.
