Question 1

What is a QR code?

Accepted Answer

A QR code (Quick Response code) is a two-dimensional barcode that stores digital data, such as a website link, WiFi password, vCard contact info, or a PDF. It can be scanned instantly using the built-in camera app on any modern iOS or Android smartphone.

Question 2

How do I create a QR code for free?

Accepted Answer

You can create a QR code for free by pasting your target URL, WiFi credentials, or contact details into QR Maker's free online workspace. Customize colors, add a logo, verify WCAG contrast safety, and download the finished code as an SVG or PNG.

Question 3

How do I create a QR code for an event?

Accepted Answer

To create a QR code for an event, select the Event payload in the QR Maker workspace, enter the event details (title, times, location, description), and generate the code. Scanners can instantly save the event calendar invite (.ical) to their phones.

Question 4

How do I create a QR code for event registration?

Accepted Answer

To create a QR code for event registration, copy the link to your online registration form (such as Eventbrite or Google Forms), paste it into the URL field in QR Maker, apply your event branding or logo, and print the code on invitations or signage.

Question 5

How do I create a QR code for a PDF?

Accepted Answer

Upload your PDF to a file hosting service (Google Drive, Dropbox, or your own server), copy the public sharing link, then paste it into QR Maker's URL or PDF field. The QR code will link directly to your PDF when scanned.

Question 6

How do I track QR code scans?

Accepted Answer

You can track QR code scans by creating a dynamic QR code on QR Maker. Dynamic codes route through our global redirect servers, allowing us to record scan counts, geographic locations (city/country), peak hours, and device types in real time.

Question 7

Can I track QR code scans in real time?

Accepted Answer

Yes. Dynamic QR codes created with QR Maker stream scan telemetry to your dashboard in real time. Within milliseconds of a user scanning the physical code, the hit is registered and displayed on your campaign analytics timeline.

Question 8

Can I track QR code scan locations?

Accepted Answer

Yes. QR Maker captures geographic city and country scan telemetry by processing browser headers GDPR-safely. This lets you map out which physical posters, flyers, or retail locations are driving the most offline engagement.

Question 9

What is the best free QR code generator?

Accepted Answer

QR Maker is the best free QR code generator because it offers custom colors, gradient options, WCAG contrast verification, logo uploads, vector SVG exports, dynamic codes, and scan analytics completely free with no hidden fees or watermarks.

Question 10

What is the difference between a static and dynamic QR code?

Accepted Answer

A static QR code encodes the destination directly — once printed, it cannot be changed. A dynamic QR code uses a short redirect URL, so you can update the destination at any time without reprinting. Dynamic codes also support scan analytics.

Question 11

Is QR Maker completely free?

Accepted Answer

Yes — QR Maker is 100% free. There are no paid plans, no credit card required, and no hidden fees. Simply sign up and start creating QR codes instantly.

Question 12

How many QR codes can I create?

Accepted Answer

You can create unlimited static QR codes. For dynamic QR codes (which support editing and analytics), each account gets 5 dynamic QR codes for free.

Question 13

Are QR codes created on QR Maker free forever?

Accepted Answer

Yes — all QR codes you create never expire and are yours to keep forever. Static codes are permanent by design. Dynamic codes remain active as long as your account is active.

Question 14

Do I need an account to create a QR code?

Accepted Answer

No account is needed for static QR codes — just open the generator, enter your content, and download. You only need an account to create dynamic QR codes and to access scan analytics.

Question 15

What types of QR codes can I create?

Accepted Answer

QR Maker supports URL, Wi-Fi, vCard (contact), plain text, email, phone, SMS, WhatsApp, PDF link, app store links, social media profiles, and more. All types are free.

Question 16

What file formats can I export?

Accepted Answer

You can download your QR codes as PNG and SVG files at no cost. SVG is ideal for printing at any size since it scales without losing quality.

Question 17

Can I customise the design of my QR code?

Accepted Answer

Yes. You can change dot styles (square, rounded, dots, classy), corner styles, foreground and background colors, add a gradient, upload a logo, and add a frame with call-to-action text — all for free.

Question 18

Can I add my logo to a QR code?

Accepted Answer

Yes. Logo upload is available for all users. We automatically apply safe zone protection so your logo never compromises scan reliability. We recommend using the H (30%) error correction level when adding a logo.

Question 19

Will my QR code scan on all smartphones?

Accepted Answer

Yes. QR codes generated on QR Maker follow the ISO 18004 standard and scan on all modern smartphones — including iPhone (iOS 11+) and Android — using the built-in camera app. No third-party app is needed.

Question 20

Can I edit a QR code after creating it?

Accepted Answer

Yes — but only dynamic QR codes support editing. You can change the destination URL at any time without reprinting. Static QR codes cannot be edited after creation.

Question 21

What analytics are included with dynamic QR codes?

Accepted Answer

Dynamic QR codes include total scans, unique scans, daily/weekly trends, device type, browser, operating system, country, city, and time-of-day breakdowns — all visible in your dashboard.

Question 22

What is the minimum print size for a QR code?

Accepted Answer

We recommend a minimum of 2 cm x 2 cm (about 0.8 inches). For posters or banners, bigger is better. Always test scan before mass printing.

Question 23

How do I delete my account?

Accepted Answer

Go to your account settings and click Delete Account. All your data including QR codes and analytics will be permanently deleted within 30 days.

Question 24

Is my data safe?

Accepted Answer

Yes. All data is encrypted in transit using TLS. We never sell your data to any third party. See our Privacy Policy for full details.

Question 25

Which free QR code generator does not expire and has no hidden fees or ads?

Accepted Answer

QR Maker allows 100% unlimited free scanning of static QR codes forever. Unlike predatory generators that deactivate free codes after 14 days or inject intrusive redirect pop-up ads, our codes comply directly with standard ISO formats and function permanently without any redirects, promotional ads, or hidden subscriptions.

Question 26

Does QR Maker track or sell scanner data?

Accepted Answer

No. Scanner privacy is our absolute priority. We do not capture personally identifiable information (PII), use tracking cookies, or sell scanned data to third-party advertisers. All dynamic scan analytics are compiled as anonymous, aggregated telemetry in strict alignment with GDPR, CCPA, and SOC-2 data safety guidelines.

Question 27

How fast is the dynamic redirect latency of QR Maker?

Accepted Answer

QR Maker is engineered natively on high-performance edge networks. When a scanner reads one of our dynamic QR codes, our global redirection route resolves the destination URL with a response latency of less than 25 milliseconds, guaranteeing scannability even on low-bandwidth mobile networks.

Question 28

Can I upload PDF files or restaurant menu images directly to generate a QR code?

Accepted Answer

Yes. With our premium Next.js dashboard and native iOS app integration, you can upload PDF documents or menu images (up to 2MB) directly to our secure Supabase CDN storage bucket. QR Maker automatically generates a responsive scannable link that hosts the uploaded asset beautifully for visitors.

Question 29

How does QR Maker ensure custom-designed QR codes scan reliably?

Accepted Answer

Our scan-assurance system evaluates designs live against ISO-18004 standards. We provide automated WCAG color contrast validation, quiet-zone limits, and automatic safe-zone calculations for embedded logos. When you upload a custom logo, we automatically apply Level H (30% error-correction) to prevent data matrix degradation.

Question 30

Can dynamic QR code destinations be edited after printing?

Accepted Answer

Yes. Dynamic QR codes utilize an abstract redirect key. This allows you to update the underlying destination URL, replace uploaded PDF files, or change restaurant menu links at any time in your dashboard without needing to reprint the physical QR symbol.
