Question 3

Do I Need an Account to Use QRStuff?

Accepted Answer

No, QRStuff allows you to create QR codes without having to sign up. However, creating an account helps you unlock advanced features such as customization.

Question 4

Can I Track QR Code Scans?

Accepted Answer

Yes. QRStuff has a dashboard solution allowing you to track the performance of your QR code such as scan count, location of scans or even device types.

Question 5

What Type of QR Codes can I Create with QRStuff?

Accepted Answer

QRStuff allows you to create all types of QR codes, such as QR codes for PDFs, for text, and even for marketing, events or retailers.

Question 6

Do QRStuff QR codes expire?

Accepted Answer

Static QR codes are free and never expire, no sign-up needed. Dynamic codes (editable, with scan tracking) are free to try: a free account gives you 10 that work for 30 days.

Question 7

Can I change the destination URL after printing my QR code?

Accepted Answer

Yes, if you use a Dynamic QR Code. Dynamic codes allow you to update the target URL, PDF, or landing page instantly without re-printing the QR code image. Static codes cannot be edited once created.

Question 8

What is the best QR code format for printing?

Accepted Answer

We recommend vector formats like SVG, EPS, or PDF for professional printing. Unlike PNG or JPG images, vector formats can be resized to any scale (from a business card to a billboard) without losing quality or becoming blurry.

Question 9

Are there scan limits on free QR codes?

Accepted Answer

No. QRStuff offers unlimited scans on all Static QR codes. You can use them for commercial purposes, marketing campaigns, or operations without worrying about scan caps or bandwidth limits.

Question 10

Does QRStuff track my data or my customers' data?

Accepted Answer

We prioritize privacy. For Static codes, we do not track scan data or store user information. For Dynamic codes, we provide anonymized scan analytics (location, device type, time) strictly for your performance tracking. We are GDPR and CCPA compliant.

Question 11

Can I create a QR code for WiFi access or a Digital Business Card?

Accepted Answer

Yes. We support over 25 data types. You can create a WiFi QR code to let guests join a network instantly without typing passwords, or a vCard QR to share contact details directly to a phone's address book.

Question 12

What is a QR Code?

Accepted Answer

A QR (Quick Response) code is a two-dimensional barcode that can be scanned using a smartphone camera or QR code reader. It can store various types of information like URLs, text, contact details, WiFi credentials, and more. Created in 1994 by Denso Wave for tracking in the automotive industry, QR codes are now used globally for marketing, payments, authentication, and information sharing.

Question 13

How do QR codes work?

Accepted Answer

QR codes work by encoding data into a pattern of black and white squares. When scanned, a QR code reader decodes this pattern back into the original information. The code contains three position markers (corners) for orientation, timing patterns for alignment, and data modules that store the encoded information. Built-in error correction in QR codes allows them to work even when partially damaged or obscured.

Question 14

What can QR codes be used for?

Accepted Answer

QR codes have countless applications: marketing campaigns posters, flyers, business cards, contactless payments mobile wallets, cryptocurrency, website/app downloads, WiFi network sharing, product information and authentication, event tickets and check-ins, restaurant menus, inventory and asset tracking, social media profile sharing, email signatures, location navigation, and much more. Any information that needs quick digital access can be encoded into a QR code.

Question 15

Are QR codes free?

Accepted Answer

Yes! Static QR codes on QRStuff are completely free to create, download, and use forever with unlimited scans. There are no hidden fees, watermarks, or expiration dates. Dynamic QR codes (which allow editing the destination and tracking scans) require a subscription, but our basic static QR code generator is free for personal and commercial use.

Question 16

What's the difference between static and dynamic QR codes?

Accepted Answer

Static QR codes permanently encode data directly into the QR code image. Once created, the content can't be changed, but they never expire and work offline. Dynamic QR codes contain a short redirect URL that points to your content. This lets you edit the destination, track scans, enable/disable codes, and add retargeting pixels without reprinting. Dynamic codes require an active subscription to maintain the redirect service.

Question 17

How big should my QR code be?

Accepted Answer

The recommended minimum size is 2 x 2 cm (0.8 x 0.8 inches) for close-range scanning. For posters or signage viewed from a distance, use the 10:1 rule: if someone scans from 3 meters away, your QR code should be at least 30 cm wide. Larger codes scan faster and work better in low light or at angles. Always test your QR code at the intended viewing distance before printing large quantities.

Question 18

What is QR code error correction level?

Accepted Answer

QR codes have four error correction levels: L Low, ~7% damage recovery, M Medium, ~15%, Q Quartile, ~25%, and H (High, ~30%). Higher error correction makes codes more resistant to dirt, scratches, or partial coverage like adding a logo, but increases code density. QRStuff automatically selects the optimal error correction based on your data type and customization, balancing scannability with reliability.

Question 19

What are dynamic QR codes?

Accepted Answer

Dynamic QR codes use a short redirect URL instead of encoding content directly. This gives you a web dashboard to edit the destination URL, file, or landing page instantly without reprinting the physical code. You also get real-time scan analytics (location, time, device type, scan count), A/B testing, scheduled URL changes, and retargeting capabilities. Perfect for campaigns, packaging, or any printed material that might need updates.

Question 20

How do I test my QR code?

Accepted Answer

Always test before printing: (1) Download your QR code in the intended format, (2) Display it at actual print size on a screen or print a test copy, (3) Use multiple smartphones (iPhone and Android) with native camera apps, (4) Test from various distances and angles, (5) Try different lighting conditions, (6) Verify the correct destination loads. For critical deployments, test with QR code scanner apps too, not just built-in cameras. QRStuff's preview feature shows your code exactly as it will appear.

Question 21

What is the maximum data capacity of a QR code?

Accepted Answer

Maximum capacity depends on data type and error correction: up to 7,089 numeric characters, 4,296 alphanumeric characters, 2,953 bytes for binary data, or 1,817 Kanji characters. However, practical limits are much lower for good scannability - aim for under 300 characters. Larger data creates denser, harder-to-scan codes. For large content (documents, videos, long text), use a URL QR code that links to your content rather than embedding it directly.

Question 22

Can I use QRStuff QR codes for commercial purposes?

Accepted Answer

Absolutely. Every QR code you generate on QRStuff, including free static codes, is cleared for commercial use without restrictions. Place them on product packaging, printed menus, retail displays, business cards, advertising campaigns, or any paid project. You don't need to credit QRStuff, pay royalties, or worry about scan volume caps. Dynamic QR codes with editable destinations and analytics only require an active subscription.

Question 23

How do I add a logo to my QR code?

Accepted Answer

Adding your brand logo takes just a few clicks inside the QRStuff generator. In the Style step, select the logo upload option and drop in your image (PNG or SVG works best). QRStuff automatically centers the logo, scales it proportionally, and raises the error correction level so your code remains fully scannable. A logo can safely cover up to 30% of the code surface without affecting reliability. While you're there, you can also customize the foreground and background colors, adjust the corner shapes, and change the dot pattern to match your brand identity.

Question 24

How do I create a QR code for a restaurant menu?

Accepted Answer

QR code menus are one of the most popular use cases on QRStuff. You have three options: (1) Upload your menu as a PDF and customers open it instantly in their browser, no app required; (2) Use a dynamic URL to link to your online menu or ordering platform, swappable any time without reprinting; or (3) Use QRStuff's landing page feature to build a branded menu page with sections per category. Download in SVG and print at 4 x 4 cm minimum for reliable table scanning.

Question 25

Can I scan a QR code without installing an app?

Accepted Answer

Yes. On most modern smartphones, no app download is needed. iPhone (iOS 11+) and Android (8.0+) both handle QR codes through the native camera app: point, hold steady, then tap the notification banner to open the link. Samsung devices work with the native camera or Bixby Vision. For older devices or codes displayed on a computer screen, you can use QRStuff's free browser-based scanner at qrstuff.com/scan, which works without any app or account.

Question 26

Can I create QR codes in bulk for a campaign or product line?

Accepted Answer

Yes. QRStuff supports bulk QR code generation for teams, agencies, and businesses. Upload a CSV or spreadsheet of URLs, product codes, or destinations, and QRStuff generates a unique QR code per row, packaged into a downloadable ZIP. Common use cases include retail and e-commerce SKU codes, event attendee check-in codes, personalized direct mail, and packaging. For very high volumes or automated workflows, the QRStuff API lets you generate, update, and manage codes programmatically.
