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

This generator covers the QR types people reach for most often. Each one uses the correct data format so iOS and Android camera apps read it on the first scan.

Restaurant and cafe owners print menu QR codes so price changes happen online, not on reprinted paper. Coffee shops, bars, and food trucks use the same trick.

Event planners add QR codes to wedding invites, conference badges, and posters. One scan can open RSVP pages, photo galleries, or directions.

Marketers place them on packaging, flyers, and storefront windows. A label can link to setup guides, warranty forms, or review pages.

Real estate agents put QR codes on yard signs. Buyers scan while standing at the property and see photos, pricing, and contact info on their phone.

Teachers print QR codes on worksheets that link to videos, quizzes, or reading material. Students scan with school devices and go straight to the resource.

Black on white works everywhere. Brand colors work too when contrast stays strong.

PNG is a raster file that works on websites, social posts, email signatures, and most print jobs. Download and use it right away.

SVG is vector. It scales to any size without jagged edges. Use it for banners, Figma layouts, Illustrator artboards, or packaging where print size varies.

Not sure? Start with PNG. Grab SVG too if you plan to resize the code in a design tool.

A QR code stores data in a grid of squares. Your phone camera reads finder patterns in the corners, decodes the binary payload, then opens a URL, shows text, dials a number, or joins WiFi.

Reed-Solomon error correction lets partially dirty or covered codes still scan. Higher correction adds redundancy, so the code gets denser and may need to print larger.

Size matters. Aim for at least 2 cm by 2 cm (about 0.8 inches) at close range. For posters viewed from farther away, print bigger. Scan distance should stay within about ten times the code width.

Contrast matters more than color flair. Dark foreground on a light background scans best. Test with your phone before you print hundreds of copies.

Add a short call to action nearby. Scan for menu or Scan to connect to WiFi beats a bare code with no context.

Always test once before a big print run. Five seconds with your camera saves a box of bad flyers.

WiFi QR codes skip the password spelling game. Guests scan, see the network name and encryption type, and tap connect.

Hosts, office lobbies, coffee shops, and home parties print a small card or sticker near the entrance. Need a strong guest password first? Use our password generator, then encode the result here.

QR codes are two-dimensional and hold URLs, WiFi strings, and contact data. One-dimensional barcodes like UPC and Code 128 suit retail shelves and warehouse labels. For those formats, use our barcode generator.
