Question 1

How does a QR code generator work?

Accepted Answer

Our platform takes the information you enter — a URL, WiFi details, contact card, and more — and encodes it into a scannable QR code pattern. Any smartphone camera can then read that pattern and instantly open the linked content, no app required.

Question 2

Do I need technical skills to create QR codes?

Accepted Answer

Not at all. Just choose a QR code type, fill in a short form, and your code is generated instantly. No design or coding experience needed.

Question 3

How is this platform different from a free QR code generator?

Accepted Answer

FreeOnlineQR gives you unlimited static QR codes for free, plus optional dynamic QR codes, custom colors, logo embedding, and scan tracking once you create a free account.

Question 4

Can I download the QR codes created during my trial?

Accepted Answer

Yes — every QR code you generate can be downloaded instantly in PNG or SVG format, completely free.

Question 5

How is a QR code different from a barcode?

Accepted Answer

A barcode is one-dimensional and typically holds around 20-25 characters, read in a single direction. A QR code is two-dimensional, can hold thousands of characters (a full URL, WiFi credentials, a contact card), can be scanned from any angle, and keeps working even if part of it is smudged or damaged.

Question 6

Is it free to make a QR code?

Accepted Answer

Yes. Every static QR code type — website, text, email, SMS, phone, WiFi, and vCard — is free forever, with no sign-up and no expiration. Dynamic QR codes (links, PDFs, menus, business profiles) require a free account since they need a hosted page behind them.

Question 7

What content types can I store in a QR code?

Accepted Answer

Websites, plain text, email, SMS, phone numbers, WiFi credentials, vCards, PDFs, images, restaurant menus, link lists, and business profiles.

Question 8

Can I add my logo and brand colors?

Accepted Answer

Yes. The generator lets you set a custom foreground and background color and upload a logo that sits in the center of your QR code.

Question 9

Will adding a logo make my QR code harder to scan?

Accepted Answer

No — we automatically use a higher error-correction level whenever a logo is added, so the code stays reliably scannable.

Question 10

How long does it take to design and deploy the QR solution?

Accepted Answer

Under a minute. Fill in your details, preview instantly, and download or save — no waiting.

Question 11

What size should I print my QR code at?

Accepted Answer

For posters and signage, at least 3 x 3 cm (about 1.2 x 1.2 inches) at 300 DPI. Download the SVG format for crisp results at any size.

Question 12

Do QR codes expire?

Accepted Answer

Static QR codes (website, text, email, SMS, phone, WiFi, vCard) never expire and need no account — the content is encoded directly into the pattern. Dynamic QR codes (links, PDFs, menus, business profiles) stay active as long as your account is active, and you can edit their destination anytime without reprinting.

Question 13

Can I track how many times my QR code was scanned?

Accepted Answer

Yes, dynamic QR codes saved to your dashboard track total scans automatically.

Question 14

Which scanner apps work with these QR codes?

Accepted Answer

Any standard camera app on iOS or Android, plus all major third-party QR scanner apps.

Question 15

Can I scan a QR code without an internet connection?

Accepted Answer

Static QR codes — WiFi, vCard, plain text, phone, and SMS — decode entirely on-device, so they work with no internet connection at all. Website links and dynamic QR codes (links, PDFs, menus, business profiles) need an internet connection to open the destination page.

Question 16

Are QR codes secure?

Accepted Answer

The QR code itself is just a pattern encoding data — it can't run code or install anything on its own. As with any link, only scan codes from sources you trust, since a QR code can point to any URL just like a typed link can. Dynamic QR codes you create here always redirect through freeonlineqr.com, so the destination can be reviewed and updated anytime.
