Frequently Asked Questions

Yes. Static QR codes — URL, text, WiFi, and vCard — are free with no sign-up, no watermark, no scan limits, and no expiration. Premium only covers dynamic codes with editable destinations and scan analytics.

No. Static codes encode your content directly into the image. Once you download the file, it works forever — there is no server dependency and nothing we could turn off even if we wanted to.

No. The generator runs entirely in your browser using JavaScript. URLs, WiFi passwords, contact details, and uploaded logos never leave your device.

Static codes contain the content itself and work forever without any account. Dynamic codes contain a short redirect link, which makes the destination editable and scans trackable — but requires a service to keep running. We offer static free and dynamic as Premium.

Yes. Use them on packaging, menus, business cards, billboards — anything. There is no license fee, no attribution requirement, and no watermark.

A rough rule: minimum size = scan distance ÷ 10. A code scanned from 25 cm (a table menu) should be at least 2.5 cm wide. For posters, download the 2048px PNG or the SVG, which scales to any size without quality loss.

The usual culprits: too little contrast between colors (keep dark modules on a light background), a logo that is too large, printing too small for the scan distance, or too much content making the modules tiny. Try High error correction and test with a real phone before printing.

Up to about 3KB, but practical limits are lower — roughly 300 characters keeps the code easy to scan. For long content, encode a URL that points to the content instead.

Static codes cannot be tracked — scans go straight to the destination, which is also why they are private and free. Scan tracking requires a dynamic code, which is part of our Premium plan.

PNG for websites, email, and social media. SVG for print — business cards, packaging, and signage — because it is a vector format that stays sharp at any size.
