About this tool
QR Code Generator creates scannable QR codes for URLs, plain text, email, phone numbers, WiFi credentials, and vCards. It is useful for print materials, packaging, product cards, event signage, menus, onboarding flows, and any workflow that needs a fast bridge from physical space to digital action.
When to use it
- •Make a branded QR code for a poster, flyer, product insert, or exhibition label.
- •Generate WiFi, contact, email, or phone QR codes that people can scan instantly.
- •Export PNG or SVG for web, print, stickers, packaging, or signage.
Best for
- •Designers who want quick QR output with color and logo customization.
- •Businesses making print collateral, menus, event materials, or packaging.
- •Creators who need a privacy-friendly browser tool instead of a hosted QR platform.
Output and privacy
- •Outputs PNG and SVG QR codes for download and reuse across print and digital media.
- •Generation happens locally in the browser.
- •Sensitive content like WiFi credentials or contact details does not need to be uploaded to a third-party service.
Limitations
- •Low contrast color combinations can hurt scannability.
- •Large logos or dense content increase code complexity and can reduce scan reliability if overdone.
- •A generated QR code is static unless the encoded destination itself is managed elsewhere.
Example use cases
- •Create a WiFi QR code for a studio guest network and print it on a small card.
- •Export an SVG QR linking to a product page for use on packaging.
- •Generate a branded contact QR with vCard data for an event badge or business card.

Frequently Asked Questions
What does this QR code generator do?
This tool creates QR codes for common data types including URLs, text, email, phone numbers, WiFi credentials, and vCards. It also supports custom colors, logo overlays, and downloadable PNG or SVG output.
When should I use a QR code generator?
Use it whenever you need to connect something physical to a digital destination quickly, for example posters, packaging, menus, event signage, contact cards, or WiFi sharing.
What data types can I encode in a QR code?
URLs, plain text, email addresses, phone numbers, WiFi credentials, and vCards. Each type formats the data optimally for QR readers.
Can I add a logo to the QR code?
Yes. Upload a logo image and it will be centered on the QR code. The error correction level adjusts automatically to ensure the code remains scannable.
Can I customize the colors?
Yes. Set custom foreground and background colors. Make sure there's enough contrast for reliable scanning.
What export formats are available?
PNG for raster use and SVG for scalable vector output. SVG is ideal for print materials where you need crisp edges at any size.
What is error correction level?
Error correction determines how much of the QR code can be damaged or obscured and still scan correctly. Higher levels (H = 30%) allow for logo overlays but increase code density.
Is this QR code tool private?
Yes. QR generation runs in the browser, so the content you encode is not sent to Hartool servers.
