QR Code Generator
QR Code Generator turns any link, text, Wi-Fi details or contact info into a scannable QR code. Print it on packaging, add it to business cards, or link customers straight to your product page.
You control the size and error-correction level (higher levels stay scannable even if partly damaged), then download a crisp PNG ready for print or web.
How to use the qr code generator
- Enter your text or URL — e.g. your website, menu link or UPI/payment address.
- Choose size and error correction (M is a good default).
- Click “Generate QR code” and preview it instantly.
- Download the PNG and use it anywhere — print, packaging, social posts.
Key features
- Any content: URLs, plain text, contact details, Wi-Fi credentials.
- Print-ready PNG: high-resolution download with quiet-zone margin.
- Error correction: L/M/Q/H levels so codes survive damage or logos.
- Free forever: unlimited codes, no watermark, no account.
vCard and WiFi QR Codes
Beyond links and plain text, this generator creates vCard QR codes — encode your name, phone number, and email so anyone can save your contact details with a single scan. It also makes WiFi QR codes, so guests can join your network by scanning one code instead of typing a long password. You can even add your logo to the center of the code for branded, professional sharing.
Frequently asked questions
Do QR codes expire?
No — a QR code is just an encoding of your text. It works forever. (Only the website it points to could change or go offline.)
What error-correction level should I use?
M (15%) is fine for screens. Use Q or H for printed codes that might get scratched, folded or partially covered by a logo.
Can I put my logo in the middle?
Higher error-correction levels (Q/H) tolerate a small logo overlaid on the center — generate at H if you plan to do this.
Is there a limit to how much text fits?
Yes — QR codes hold roughly 4,000 characters max, but shorter content scans faster and more reliably. Keep URLs short.
Can I create a QR code for my YouTube channel?
Yes — paste your channel URL, generate the code, and print it on cards, banners, or packaging.
What is a vCard QR code?
A QR code that contains contact details. When scanned, the phone offers to save you as a contact — no typing needed.
Do the QR codes have a watermark or expiry?
No watermark, and the codes don’t expire. They encode your data directly, so they work forever.
How do I make a QR code for my WiFi?
Select the WiFi QR option above, enter your network name and password, and download the code — guests scan it to connect instantly, no typing needed.
Pro Tips
- Print size matters: for business cards use at least 2×2 cm; for posters viewed from afar, go much larger.
- Test before printing: scan the downloaded QR with two different phones to confirm it reads reliably.
- Keep URLs short — shorter content means a simpler, easier-to-scan code. Use a short link for long URLs.
More FAQs
Where can I use these QR codes?
Business cards, product packaging, restaurant menus, event posters, Wi-Fi sharing, payment links, and app download pages.
Do I need to credit anyone?
No — codes generated here are free for personal and commercial use with no attribution required.
How It Works: Under the Hood
A QR code encodes data in a grid of modules using one of four modes: numeric (digits only, 3⅓ bits per digit — most efficient), alphanumeric (digits + uppercase + a few symbols, 5.5 bits per char), byte (any data, 8 bits per char — used for URLs), and kanji. The encoder picks the densest mode that fits your content, then adds Reed-Solomon error correction at one of four levels: L (7% recoverable), M (15%), Q (25%), H (30%). That’s why a QR code with a logo punched through its center still scans — up to 30% of the pattern can be destroyed and the data reconstructs perfectly.
The three big squares (finder patterns) let scanners detect orientation instantly, while timing patterns and alignment markers handle perspective distortion — which is why phones read QR codes at angles, in bad light, off curved surfaces.
Real-World Use Cases
- Restaurant menus: printed table tents link to a digital menu — update prices online without reprinting. Use H-level error correction since cards get greasy and scratched.
- Event check-in: conferences email each attendee a unique QR ticket; scanners at the door validate in under a second, no app needed.
- Product packaging: cosmetics brands link to ingredient lists and tutorial videos — the code is tiny on the box but H-correction survives crinkled packaging.
- Real-estate signs: “scan for virtual tour” on yard signs captures drive-by interest at the moment of curiosity.
- Wi-Fi sharing: cafés print a QR encoding the network credentials — guests join without asking staff or typing 20-character passwords.
Advanced Tips
- Shorten URLs before encoding. A 100-character URL needs a denser (harder-to-scan) QR version than a 20-character short link. Every character saved makes the code simpler and more reliable.
- Match error correction to the environment. Pristine screen display? Level L is fine and produces the cleanest code. Printed materials that get handled, folded, or rained on? Use Q or H.
- Mind the quiet zone. QR specs require a 4-module blank margin around the code. Designs that crowd text against the edge cause scan failures — the #1 real-world issue.
- Test at actual size and distance. A code that scans on your monitor may fail when printed 2 cm wide on a business card. Print a proof and test with two different phones.
Common Mistakes to Avoid
- Linking to URLs you don’t control long-term. A QR on 10,000 printed flyers pointing to a page you’ll redesign next year is a liability. Use a redirect/short link you can repoint.
- Placing the logo too large. The center overlay must stay within the error-correction budget — cover more than ~25% and scans fail. When in doubt, use H level and keep the logo modest.
- Inverting colors carelessly. White-on-black QR codes fail on many scanners (they expect dark-on-light). Some readers handle it; many don’t. Stick with dark modules on light background.
- Using them where there’s no signal. A QR linking to a video in a basement parking garage is useless. Match the destination to the location’s connectivity.
QR Codes for Your Social Profiles
Put a scannable code on your business card, packaging, or poster that opens your YouTube channel, Instagram, or LinkedIn instantly. Type the link, generate, download the PNG — done in under a minute. Shorten long links first with the URL tools if needed.
