Square PNG with a transparent background works best. Error correction switches to Max automatically while a logo is active.

Every QR code is created by JavaScript running directly in your browser. Your URLs, WiFi passwords, and contact details never leave your device. Unlike most QR tools, we physically cannot see what you create.
LightningQR creates static QR codes that encode your data directly into the pattern. There is no server redirect, no subscription to cancel, and no account to close. Print them on a wedding invitation — they will still scan in 2050.
Most QR generators force you to create an account before downloading. LightningQR requires nothing — no email, no name, no payment details. Open the page, create your code, and download it in under 10 seconds.
Download a crisp 1000 × 1000 px PNG for digital use, or a perfect vector SVG for business cards and print at any scale. Both formats are always free — no paid plan, no watermark, no hidden limit.
Every QR code carries built-in repair data. If part of the pattern gets scratched, dirty, or covered by a logo, a scanner can still reconstruct the missing pieces and read it correctly. The error correction level you choose controls how much repair data is included — higher levels survive more damage, but produce a denser pattern.
Survives up to 7% damage
The smallest, cleanest pattern. Best for digital screens and perfect printing conditions — or when your content (like a long URL) is already pushing the QR code's size limit.
Survives up to 15% damage
The right balance for almost everything — business cards, posters, product packaging. This is the industry-standard default and works reliably in most real-world conditions.
Survives up to 25% damage
Built for tougher environments — outdoor signage, fabric printing, or surfaces with texture and wear. A good choice when the QR code won't be handled under ideal conditions.
Survives up to 30% damage
Maximum resilience. Use this when adding a logo overlay, printing on heavily textured or worn surfaces, or any situation where part of the code may be obscured.
Select from URL, WiFi, WhatsApp, contact card, email, phone, SMS, or plain text — whatever your QR code needs to do.
Fill in the relevant details — a URL, your WiFi password, a phone number, or a message. The QR code updates as you type.
Click Download PNG for digital use, or Download SVG for print. Your code is generated instantly — no waiting, no email confirmation.
Encodes any website address so scanning opens the link automatically — no typing required. The most widely used QR code type, ideal for business cards, product packaging, restaurant menus, and any print material where you want to direct people online.
Lets guests connect to your WiFi network by scanning, without typing the password. Encodes your network name (SSID), password, and security type. Perfect for cafes, hotel rooms, offices, conference venues, and home use when hosting guests.
Opens a WhatsApp chat with a specific phone number when scanned, with an optional pre-filled message. Widely used for business customer service, marketing campaigns, and quick contact links on printed materials — especially popular in India.
Encodes a digital business card including name, phone, email, company, job title, and website in vCard 3.0 format. When scanned, most phones offer to save the contact directly to the address book — the modern replacement for paper business cards.
Opens the email app with a pre-filled recipient, subject line, and body text. Useful for customer feedback forms, event registrations, and support contacts — any situation where you want to make it effortless to send a specific email.
Opens the phone dialler with a number pre-filled, ready to call with one tap. Used on business signage, product packaging, service directories, and anywhere you want to remove the friction of dialling a number manually.
Opens the messaging app with a phone number and optional pre-written message ready to send. Useful for opt-in campaigns, appointment confirmations, order requests, and any text-based customer interaction that requires a quick response.
Encodes any text content directly — a note, code, address, product details, or any information. When scanned, the text is displayed on screen. Useful for product instructions, serial numbers, event access codes, and offline data transfer.
Yes, completely free. All 8 QR types, PNG download, SVG download, and colour customisation are free forever. We earn through non-intrusive Google Ads shown on the page, which keeps the tool free for everyone.
Never. LightningQR generates static QR codes that encode your data directly into the visual pattern. There is no server redirect URL, no account to cancel, and no subscription to forget. Your QR code will work exactly as it does today — in ten or a hundred years.
Yes. Every QR code is generated entirely in your browser using JavaScript. Your data — whether it is a URL, a WiFi password, or someone's contact details — is never sent to our servers. We have no idea what QR code you created, and we cannot find out.
No. There is no sign-up, no email address, no name, and no payment details required. Open the page, enter your content, download your QR code, and leave. The whole process takes under 10 seconds.
Yes. LightningQR offers both a PNG download (1000 × 1000 pixels, print-ready) and an SVG download (a vector file that scales to any size without pixelation). Both formats are completely free — many competitors lock SVG behind a paid plan.
Click the WiFi tab at the top of the generator. Enter your network name (SSID), your WiFi password, and select your security type (usually WPA2). The QR code generates instantly. Anyone who scans it will be prompted to connect to your network automatically — no password typing required.
Static QR codes encode your data directly into the pattern and never expire — these are what LightningQR generates. Dynamic QR codes contain a short redirect URL that points to a server, which then forwards to your actual destination. Dynamic codes allow the destination to be changed later, but they expire or break if you cancel the subscription. LightningQR's static codes are permanent and private.
On iPhone (iOS 11 and later): open the Camera app and point it at the QR code — a notification banner appears automatically. On Android: open the Camera app or Google Lens and point it at the code. Most smartphones released after 2018 scan QR codes natively, without a separate app.
Use the SVG download for the best quality at any print size. As a general rule: at least 2 cm × 2 cm for business cards and close-range scanning; at least 10 cm × 10 cm for posters and signage viewed from over one metre away. Simpler content such as short URLs can print smaller than complex content such as full vCards.
Yes. Click "Choose image" in the Customise panel and upload a square PNG with a transparent background for best results. LightningQR automatically switches error correction to Max and locks it there while your logo is active, giving the pattern enough redundancy to stay scannable around the obstruction. For best results, keep your logo simple and avoid covering more than the centre 25% of the code.
Error correction adds repair data directly into the QR pattern, so a scanner can still read it even if part of the code is scratched, dirty, or covered by a logo. Low survives about 7% damage, Medium (the default) survives 15%, High survives 25%, and Max survives up to 30%. Higher levels create a denser pattern, so Medium is the right choice for most uses.
