QR Code Generator - Create Free Custom QR Codes for URLs, WiFi, Email & Phone

This generator covers the most common QR code types that people actually need. Each type uses the correct data encoding format so any standard QR scanner on iOS or Android reads it instantly.

Small business owners are one of the biggest user groups. If you run a restaurant, you have probably already seen QR code menus everywhere since 2020. Printing a QR code that links to your online menu saves money on reprinting physical menus every time prices change. Coffee shops, bars, and food trucks use them the same way.

Event planners use QR codes on wedding invitations, conference badges, and event posters. A QR code on a wedding invitation can link to the RSVP page, photo gallery, or directions. At conferences, QR codes on name badges let people exchange contact information without fumbling with business cards.

Marketers put QR codes on product packaging, flyers, posters, and storefront windows. A QR code on a product label can link to setup instructions, warranty registration, or a customer review page. On a poster, it bridges the gap between physical advertising and digital engagement.

Real estate agents use QR codes on yard signs and listing flyers. Potential buyers scan the code while standing in front of the property and instantly see photos, pricing, and agent contact information on their phone.

Teachers print QR codes on worksheets and classroom posters that link to videos, interactive quizzes, or supplementary reading material. Students scan with their school devices and go directly to the resource.

The default black-on-white QR code works everywhere, but customizing colors helps your QR code match your brand or design.

PNG is a raster format that works everywhere. Use it for websites, social media posts, email signatures, and most print materials. The file you download is high resolution and ready to use immediately.

SVG is a vector format that scales to any size without losing quality. Use it when you need to resize the QR code significantly, like printing it on a banner, embedding it in a design tool like Figma or Illustrator, or placing it on product packaging where the final print size varies.

If you are not sure which to choose, start with PNG. It covers 90% of use cases. Download SVG as well if you plan to do any design work with the code.

A QR code is a two-dimensional barcode that stores data in a grid of black and white squares. The name stands for Quick Response, and the format was invented in 1994 by Denso Wave, a Japanese automotive parts company, to track vehicles during manufacturing.

The code consists of several elements: finder patterns (the three large squares in the corners that help scanners orient the code), alignment patterns, timing patterns, and the actual data modules. Your phone camera reads these patterns, decodes the binary data, and performs the appropriate action - opening a URL, showing text, starting a phone call, or connecting to WiFi.

Error correction is built into the format using Reed-Solomon error correction. This is why QR codes still work even when partially obscured, dirty, or slightly damaged. Higher error correction levels embed more redundant data, which makes the code more resilient but also denser (more modules, which means the code needs to be printed larger or scanned from closer).

Size matters more than most people realize. A QR code needs to be at least 2cm x 2cm (about 0.8 inches) for reliable scanning at close range. For posters and signs that people scan from a distance, you need it much larger. The general rule is that the scanning distance should be no more than 10 times the size of the code.

Contrast is critical. The darker the foreground and lighter the background, the better. Avoid low-contrast combinations like light gray on white or dark blue on black. If you customize colors, always test the code with your phone camera before printing.

Always add a call to action near the QR code. A bare QR code with no context gets fewer scans than one that says 'Scan for menu', 'Scan to connect to WiFi', or 'Scan for directions'. People need a reason to pull out their phone.

Test before you print. Every time. Generate the code, scan it with your phone, and verify it goes to the right destination. This takes five seconds and prevents the embarrassment of printing 500 flyers with a broken QR code.

WiFi QR codes are one of the most practical QR code types. Instead of telling guests your WiFi password (and watching them type it wrong three times), you print or display a QR code that handles the entire connection process automatically.

When someone scans a WiFi QR code, their phone reads the encoded network name (SSID), password, and encryption type (WPA, WPA2, WEP, or none). The phone then prompts to connect to that network with all the details already filled in. One tap and they are online.

This is perfect for Airbnb hosts, office lobbies, coffee shops, coworking spaces, and home parties. Print the QR code on a small card, frame it near the entrance, or put it on a sticker. Guests connect in seconds without you having to spell out a complicated password.
