QR Code Generator
Generate QR codes for URLs, text, WiFi, contact info and more. Free, instant download.
About the QR Code Generator
The QR Code Generator creates high-resolution QR codes for any text, URL, Wi-Fi credential, email address, phone number, vCard contact or geolocation — instantly, in the browser, with no signup. QR codes have become an essential bridge between physical and digital: they appear on menus, business cards, product packaging, event tickets, posters and payment terminals. This tool generates codes at any size, in any colour, with optional logo overlay, and downloads them as PNG or SVG ready for print or web use.
A QR (Quick Response) code is a two-dimensional barcode that encodes data as a matrix of black and white squares. When scanned by a smartphone camera, the code decodes into text — often a URL — and the phone opens the target automatically. QR codes support error correction (levels L, M, Q, H) that lets scanners read damaged or partially covered codes, which is why a coffee-stained menu QR still works. Modern codes can hold up to about 4,000 alphanumeric characters, though shorter payloads produce simpler, faster-scanning codes.
Key Features of Our QR Code Generator
Every feature below is built for accuracy, speed and privacy — the tool runs entirely in your browser, so nothing you type is uploaded to a server or shared with third parties.
Multiple content types
URL, plain text, Wi-Fi credentials, email, phone, SMS, vCard contact card and geolocation — all supported.
Adjustable size
Generate codes from 128×128 up to 2000×2000 pixels for anything from an app screen to a billboard.
Custom colours
Change the foreground and background colours to match your brand — the tool keeps enough contrast for scanners.
Logo overlay
Embed your logo in the centre of the code without breaking scannability, thanks to error-correction level H.
PNG & SVG downloads
PNG for print materials; SVG for infinitely scalable web and vector graphics workflows.
Runs client-side
Everything is generated in your browser — no upload, no logging, complete privacy for sensitive Wi-Fi passwords.

- 3
Adjust colours & size
Optionally change foreground/background colours and pick a size in pixels.
- 4
Add a logo (optional)
Upload a PNG logo to embed in the centre — the tool automatically boosts error correction so the code still scans.

Grab the file and use it in print, email signature, product packaging or web page.
Why Choose Our QR Code Generator?
Bridge print & digital
A single scan takes a reader from a paper poster to a full landing page — no typing URLs.
Zero-friction Wi-Fi sharing
A Wi-Fi QR encodes the SSID and password so guests connect with one scan instead of dictation.
Contactless menus & payments
Popular in restaurants and retail — QRs remove the need to touch a shared surface.
Trackable marketing
Encode UTM-tagged URLs to measure exactly how many scans each print piece drove.
Free & unlimited
Generate as many codes as you need forever, at any resolution, without ever hitting a paywall.
Common Use Cases
The QR Code Generator is trusted by students, writers, marketers, developers and everyday users worldwide. Here are some of the most common scenarios where it saves time and delivers reliable results.
Restaurants & cafes
Digital menus, feedback forms, loyalty programme signups.
Retailers
Product-detail pages, reviews, warranty registration, promotional discounts.
Events & tickets
Scan-in check-in, session schedules, feedback surveys.
Business cards
A vCard QR lets recipients save your contact with a single scan — no typing.
Home Wi-Fi guests
Print the QR beside your router — guests connect in one tap without asking for the password.
Payment prompts
Encode UPI, PayPal or JazzCash links for instant merchant payments.
Best Practices & Tips
Keep payloads short
Short URLs (or URL shorteners) produce simpler, faster-scanning codes.
Test before printing
Scan every generated code with multiple phones before sending to a print job — a wrong URL wastes an entire run.
Choose enough contrast
Dark foreground on light background is safest. Reversed schemes may fail on older scanners.
Include a call-to-action
A short "Scan for menu" or "Scan to Wi-Fi" prompt beside the code lifts scan rates dramatically.
Use error correction wisely
Level H (30% recoverable) is best when you overlay a logo or expect physical damage; L (7%) makes cleaner codes but is fragile.
Frequently Asked Questions
Do QR codes expire?
The code itself never expires — it is just data. But if it links to a URL you take down, the code becomes useless. Consider using a permanent redirect URL you control.
Are QR codes safe?
Codes generated here are safe. Codes found in the wild may lead to phishing sites — always preview the URL after scanning if your phone offers a preview option.
How much data can a QR code hold?
Up to 4,296 alphanumeric characters or 7,089 digits, but shorter data produces simpler, more reliable codes.
What is the minimum size for a printed QR?
About 2×2 cm for a smartphone at 30 cm reading distance. For billboards, scale up proportionally to expected scanning distance.
Do QR codes work in low light?
Modern phones handle low light well thanks to camera flash and image stabilisation. High-contrast printing helps most in dim environments.
Can I edit a QR code after printing?
The code itself cannot be edited. But if it points to a URL you control, you can change the destination page without reprinting.
Does adding a logo break the QR code?
No, as long as the logo covers ≤30% of the code and you use error-correction level H (30% recovery). This tool sets that automatically when you upload a logo.
Can I generate a Wi-Fi QR code?
Yes — pick the Wi-Fi content type, enter your SSID, password and encryption type, and the tool generates a code that connects any scanning device with one tap.
Are the codes trackable?
Not directly. Trackability requires linking the QR to a redirect URL you control (with UTM parameters or a shortener with analytics).

Privacy, Security & Trust
The QR Code Generator is built with a privacy-first philosophy. Every calculation, encoding and transformation runs entirely inside your web browser using standard JavaScript APIs — nothing you type, paste or upload is transmitted to our servers, logged, cached or shared with any third party. You can verify this yourself by opening your browser's developer tools and watching the Network tab while you use the tool: you will see zero outbound requests for the actual computation.
This client-side architecture matters most when you are working with sensitive text — an unpublished blog draft, a legal notice under embargo, an internal meta description, or a password you are about to set. On many competing sites, similar tools quietly send every keystroke to their servers for "processing", which becomes a real leak vector. Ours does not, and it never will.
The tool is completely free with no daily quotas, no watermarks and no forced sign-up. It works on desktop and mobile browsers, on slow and fast connections, and continues to function offline once the page has loaded. All source code, formulas and character tables used by the tool are standard, well-documented and independently verifiable — which is essential for anything you plan to use for legal, medical, financial or educational purposes.
