Free QR Code Generator: Custom URLs, Wi-Fi & SVG Export
Create high-resolution, vector-quality QR codes for websites, Wi-Fi networks, and text with instant PNG/SVG download.
Professional QR Code Studio & Generator
Generate permanent, 100% scannable static QR codes for links, Wi-Fi passwords, contact cards, and text with zero redirects or expiry.
When scanned by any camera, this URL will open directly in the user's mobile browser.
What this tool does and who it is for
Makes static QR codes for a web address, plain text, Wi-Fi login, email, phone number or contact card. Choose colors, size, margin and error-correction level, then download a PNG or SVG, or copy the image. The code holds your data directly, so it will not expire or route through anyone's server.
Static means the content is printed into the pattern. That is great for permanence and privacy, but you cannot edit it later or track scans. If the link changes, you need a new code.
Always scan your finished code with a couple of phones before printing. Contrast, quiet-zone margin and size are what break codes in the real world.
Official Formula / Technical Standard
Real-World Worked Scenario
URL: 'https://stackverdictlab.com' encoded at Error Correction Level M generates a clean 29x29 module matrix that scans instantly on iOS and Android camera apps.
When people use it
Restaurant and cafe menus
Point a table card to your online menu. SVG output prints crisply at any size.
Guest Wi-Fi
Print a Wi-Fi code for an Airbnb, office lobby or waiting room so guests join without typing a password.
Business cards and flyers
Use the contact card option so a scan saves your name, phone, email and website straight into someone's address book.
Event and yard-sale signs
A short URL in a QR code lets passersby open a page or map without remembering anything.
Notes for US users
- US phones read QR codes straight from the camera app on both iPhone and Android, so you rarely need to tell people to download a scanner.
- Keep dark modules on a light background with strong contrast. Light-on-dark and low-contrast brand colors fail on many phones.
- For print, aim for at least about 1 inch (2 cm) per side at a normal reading distance, and larger for banners or distant signs.
- Wi-Fi codes contain the password in plain form, so anyone who photographs the sign can read it.
Limits and what to double-check
- •Static codes cannot be edited after printing and do not report scan counts.
- •Adding a logo over the middle is not built in. If you cover part of the code, use the high error-correction level and test carefully.
- •Very long URLs or text make a dense code that is hard to scan at small sizes. Shorten the link first.
Expert Best Practices & Common Pitfalls
Recommended Best Practices
- •Select Higher Error Correction (Level Q or H) if you plan to place a logo in the center or use the QR code in outdoor print environments where minor scratches may occur.
- •Always test your generated QR code across multiple devices (iPhone and Android) at various distances before sending to print.
- •Maintain a high contrast ratio (dark code on light background) and provide a quiet zone (white border) around the code.
Common Mistakes to Avoid
- •Inverting colors (light code on dark background), which many older phone camera sensors struggle to recognize.
- •Printing QR codes on highly reflective or curved surfaces without sufficient size.
- •Encoding excessively long URLs without shortening or cleaning them first, resulting in tiny, dense, hard-to-scan dots.

Frequently Asked Questions
Do the QR codes generated here ever expire?▼
No. The QR codes created with this tool are direct static codes. Your data (URL, Wi-Fi credentials, or text) is encoded directly into the pixel pattern. There are no redirect servers, no accounts, and no expiration dates.
What is the best format for printing QR codes on banners or flyers?▼
Always choose SVG (Scalable Vector Graphics) for commercial printing. SVG files can be enlarged to billboard size without any pixelation or loss of sharpness.
Which error-correction level should I choose?▼
Medium suits most cases. Choose High if the code will be printed on rough surfaces, partly covered or given a logo, at the cost of a denser pattern. Low gives the simplest pattern but little tolerance for smudges or damage.
PNG or SVG for printing?▼
Choose SVG for anything printed at larger sizes, such as posters, signs and packaging, since it stays sharp when scaled. Use PNG for web pages, slides and documents. If you use PNG for print, export at a large size.
Is a QR code with a Wi-Fi password safe to display?▼
It exposes the password to anyone who can see or photograph the code, same as writing it on the wall. For a guest network that is usually fine. Use a separate guest network, not your main one, and change the password if it leaks.
Why will my QR code not scan?▼
Common causes are low contrast, a missing blank border, printing too small, or too much data packed into the code. Increase the size, use black on white, keep the margin and shorten any URL. Test with both an iPhone and an Android phone.
