QR Code Generator — Free Online Tool

What Is QR Code Generator?

A free online QR code generator. Create QR codes for URLs, WiFi passwords, email, phone numbers, or any text. Customize foreground and background colors, choose error correction level, and download as high-resolution PNG or scalable SVG — all in your browser, no sign-up required.

A QR code generator is one of the most versatile tools in any digital toolkit. Whether you need to share a website link, let guests connect to your WiFi without typing a password, or encode contact information on a business card, QR codes bridge the gap between the physical and digital worlds instantly.

Our free QR code generator runs entirely in your browser — no data is ever sent to a server. You can create custom QR codes in seconds: enter your content (URL, text, WiFi credentials, email, phone number, or SMS), choose a color theme that matches your brand, adjust the size and error correction level, and download the result as a high-resolution PNG for web use or a scalable SVG for print. The SVG format is particularly valuable for large-format printing like signage, posters, and product packaging, as it stays crisp at any resolution.

What sets this generator apart is the flexibility. You are not limited to black-and-white squares — customize the foreground and background colors to align with your brand identity, making QR codes that actually look good on your marketing materials. The error correction options (L, M, Q, H) let you balance between data density and resilience: higher error correction means the code remains scannable even if partially obscured or damaged, which is essential for outdoor use or products that may get scuffed.

Real-World Use Cases for QR Code Generator

WiFi Guest Access

Print a QR code and place it in your living room, office, or cafe. Guests scan it with their phone camera and connect to your WiFi instantly — no more spelling out long passwords. The WiFi preset automatically formats the network credentials in the correct WPA standard.

Business Cards & Networking

Generate a vCard QR code containing your name, phone, email, and company. Add it to your business card or email signature. When someone scans it, your contact details are saved directly to their phone — much faster than typing manually.

Product Packaging & Marketing

Add QR codes to product labels linking to instruction manuals, warranty registration, or promotional landing pages. Customize the colors to match your brand palette. Download as SVG for crisp printing at any size on boxes, bottles, or flyers.

Event Check-in & Tickets

Generate QR codes as digital tickets for events, webinars, or conferences. Each code can encode a unique attendee ID or URL. Scan at the door for fast check-in without printed tickets or manual name lookup.

Pro Tips for QR Code Generator

1Use SVG format for print materials (posters, banners, packaging) — it scales infinitely without pixelation, unlike PNG.
2Choose error correction level H (30%) for QR codes that will be printed on uneven surfaces or exposed to outdoor conditions where partial damage is likely.
3Keep the encoded URL short for denser, more reliable QR codes. If your URL is long, use a URL shortener first — shorter data means a simpler pattern that scans faster.
4Always test your QR code with both iPhone and Android cameras before printing in bulk. Different devices have different scanning sensitivities.

QR Code Generator — Frequently Asked Questions

Is the QR code generator really free?

Yes, completely free with no watermark. You can generate and download unlimited QR codes without signing up.

What formats can I download?

You can download QR codes as PNG (raster image) or SVG (scalable vector). SVG is ideal for print and large displays.

Can I create WiFi QR codes?

Yes, use the WiFi preset which formats the string as WIFI:T:WPA;S:NetworkName;P:password;; — scanning it will auto-connect.

What is error correction and which level should I choose?

Error correction (L, M, Q, H) determines how much of the QR code can be damaged while still being scannable. Level L (7%) is fine for digital screens. Level M (15%) is a good default for most uses. Level H (30%) is best for outdoor signage, product packaging, or any scenario where the code might get scratched or partially covered.

Can I customize the colors of my QR code?

Yes, you can set custom foreground and background colors. Choose colors that match your brand. Ensure sufficient contrast between foreground and background — dark foreground on light background works best for reliable scanning.

Do QR codes expire?

Static QR codes (encoding text or URLs directly) never expire. However, if the QR code encodes a URL and that URL stops working or the linked page is taken down, the QR code will lead to a dead link. For long-term use, encode information that will remain valid, or use a URL you control.
