Question 1

Is Free QR Code Hub really free?

Accepted Answer

Yes. Every feature — unlimited generation, PNG/JPG/SVG/PDF/ZIP exports, logo upload, gradient patterns, and AI style presets — is 100% free. No signup, no watermark.

Question 2

Do QR codes expire?

Accepted Answer

No. Every code you generate with Free QR Code Hub is static and permanent. Scan it in 10 years and it'll still work as long as the destination is live.

Question 3

Do I need to create an account?

Accepted Answer

No account required. Everything runs in your browser. Optional accounts (via Dashboard, coming soon) unlock saving, analytics, and dynamic redirects.

Question 4

Can I use Free QR Code Hub for commercial projects?

Accepted Answer

Absolutely. Codes are royalty-free. Use them on products, packaging, ads, business cards, or anywhere your brand lives.

Question 5

What file formats can I download?

Accepted Answer

PNG (transparent-ready raster), JPG (smaller for email), SVG (vector, infinite resolution), PDF (print-ready with layout), and ZIP (all four bundled).

Question 6

Which format is best for print?

Accepted Answer

SVG. It's a vector format that scales cleanly to billboards or business cards. Use PDF when you need a specific paper size layout.

Question 7

Which format is best for web?

Accepted Answer

PNG for most cases — it's crisp and supports transparency. Use SVG when you want the code to remain sharp on any zoom level.

Question 8

Will adding a logo break scanning?

Accepted Answer

Not if you keep error correction at level H, which lets Free QR Code Hub tolerate up to 30% obstruction. Our logo placement engine sizes and centers the mark safely.

Question 9

What is error correction (L/M/Q/H)?

Accepted Answer

It's the redundancy built into a QR code. L allows 7% obstruction, M 15%, Q 25%, H 30%. Higher levels create denser codes but survive damage, styling, and logo overlays.

Question 10

Do gradients affect scannability?

Accepted Answer

Not if there's enough contrast between the foreground gradient and the background. Free QR Code Hub validates contrast automatically and warns if a preset dips below the safe zone.

Question 11

What content types are supported?

Accepted Answer

Websites, WiFi, WhatsApp, Instagram, Facebook, TikTok, YouTube, phone, email, SMS, PDF, business cards, vCards, Google Maps, calendar events, crypto wallets, payments, restaurant menus, Google Forms, and plain text.

Question 12

Can I generate WiFi QR codes?

Accepted Answer

Yes. Pick the WiFi type, enter SSID, password, and security mode, and Free QR Code Hub builds the standardized WIFI: string that iOS and Android decode natively.

Question 13

Are my codes private?

Accepted Answer

Yes. QR codes render entirely in your browser — nothing about the destination content is sent to our servers. We don't log payloads, ever.

Question 14

Is Free QR Code Hub SEO friendly?

Accepted Answer

The site is built on TanStack Start with server-side rendering, structured data, canonical URLs, and Core Web Vitals in mind. Codes themselves don't affect SEO — they're just images.

Question 15

Can I resize the exported QR code?

Accepted Answer

Yes. Use the export size slider (256px–1600px). SVG scales infinitely, so pick that for print or unknown final sizes.

Question 16

Why is my QR code not scanning?

Accepted Answer

Common causes: low contrast between foreground and background, too small on-screen size (aim for at least 2cm printed), or aggressive cropping. Bump error correction to H and try again.

Question 17

Do you offer an API?

Accepted Answer

The Free QR Code Hub REST API is in private beta. Visit the API page to request early access.

Question 18

Do you track scans?

Accepted Answer

The public generator does not — everything runs in the browser. When Dashboard launches, opt-in dynamic redirects will provide scan analytics.

Question 19

Which browsers are supported?

Accepted Answer

Every modern browser: Chrome, Safari, Firefox, Edge, and Arc. Mobile Safari and Chrome for Android are fully supported for design and download.

Question 20
