Generated locally in your browser. The content is not uploaded.
Readability and export
M is recommended for most screens and printed documents. Use H when a small logo may cover part of the code.

How to use QR Code Generator
Common use cases
- Links and documents
- Share an HTTPS page, form, menu or documentation.
- Wi-Fi access
- Encode SSID, security and password in a structured Wi-Fi payload.
- Contact card
- Share a vCard 3.0 with name, phone, email, organization and website.
- Mobile action
- Prepare an email, phone call or SMS after scanning.
Limits and good practices
Good practices
- Keep a quiet zone of at least four modules.
- Use a dark foreground on a light background.
- Prefer SVG for print and PNG for fixed screen sizes.
- Keep payloads concise to reduce density.
Common mistakes
- Unnecessarily long content
- More bytes increase the QR version, module count and required physical size.
- Removed quiet zone
- Tight cropping removes the clear area scanners use to isolate the symbol.
- Low contrast
- A dark background or pale foreground reduces scan reliability.
FAQ
Frequently asked questions
Which content types can the generator encode?
It creates QR codes for URL, text, Wi-Fi, vCard 3.0, email, phone and SMS.
Does the generated QR code expire?
No. It is static and stores its content in the matrix, although an encoded webpage can disappear.
What is the difference between PNG and SVG?
PNG is raster-based for fixed screen sizes. SVG is vector-based and stays sharp when resized for print.
Which error correction level should I use?
M is a practical default. Q or H adds redundancy for limited damage but produces a denser matrix.
Why does the quality panel report high density?
Payload length and correction level determine the QR version. Shorter content can reduce the module count.
How much quiet zone does a QR code need?
Standard QR codes use four clear modules on each side. The generator offers 4, 6 and 8 module margins.
Are entered values uploaded?
No. Payload, matrix, PNG and SVG files are generated locally in the browser.
How can I test the downloaded QR code?
Import it into the OnSubmit QR reader or tester and verify the exact payload, hostname and warnings before printing.
