Frequently asked questions

QR DNA is a QR code generator and digital business card platform. You can create styled, correctly encoded QR codes in the browser, download them as vector or raster files, and optionally create dynamic codes whose destination you can change after printing — with scan analytics to see how they perform.

Yes. Every feature is free while QR DNA is in early access. Paid plans may be introduced later, but codes you generate and download are yours to keep either way.

No. You can generate and download static QR codes without signing up. An account is needed for the features that require us to store something for you: dynamic codes, saved codes and projects, analytics, and digital business cards.

Ten content types: URL, plain text, email, phone number, SMS, Wi-Fi credentials, vCard contact, location, calendar event, and App Store links. Each payload is written the way its own specification expects, so a Wi-Fi code actually joins the network and a vCard saves cleanly to contacts.

Static codes never expire. The destination is encoded directly in the pattern, so the printed code keeps working forever — it doesn't depend on QR DNA existing. Dynamic codes route through a qrdna.io short link, so they work for as long as the service hosts the redirect.

Five formats: SVG and PDF are vector — they open in Figma, Illustrator and InDesign and scale to any size without blurring. PNG, JPEG and WebP are raster, exported at whatever pixel size you choose. For anything going to print, use SVG or PDF.

Yes. You can style the modules, corners and colors and drop a logo into the center. QR codes carry built-in error correction, which is what lets scanners reconstruct the data hidden behind a logo. Two habits keep styled codes reliable: keep strong contrast between the code and its background, and test-scan with a phone before printing a large run.

A common rule of thumb is scan distance ÷ 10. A code scanned from about 30 cm away — a flyer or business card — should be at least 3 cm wide. For posters and signage viewed from farther away, scale up accordingly, and always do a test scan at real size.

A static code encodes your content directly in the pattern — it works forever, needs no account, and can never be changed. A dynamic code encodes a short qrdna.io link that redirects to your destination, which means you can change where it points after it's printed, and every scan can be counted.

Yes — if it's a dynamic code. Edit the destination in your dashboard and every existing print of the code follows the new destination immediately. Static codes cannot be re-pointed, so if you expect the destination to change, make the code dynamic before you print.

For dynamic codes: scans over time, unique versus repeat scans, device type, operating system and browser, approximate location (country, region and city), and referrer. Digital business cards get view analytics on the same model. Everything can be exported as CSV. See the privacy policy for exactly what a scan records.

A hosted personal page with your name, role, contact details, links and photo, reachable by QR code or link. Visitors can save your details straight to their phone's contacts with one tap. Four layouts are available, and the card can be updated any time without reprinting anything.

Capacity. A vCard with a photo is far more data than a scannable QR code can hold — codes get denser and harder to scan as the payload grows. Pointing the code at a hosted card keeps the pattern simple enough to scan from across a table, and the contact file visitors download can include your photo and always reflects your latest details.
