About
An online tool that instantly generates QR codes from text, URLs, email addresses, phone numbers, etc. We also support customization of color and size.
The generated QR code can be saved as a high-quality PNG image. You can use it as is for printed materials such as business cards, flyers, and posters.
All processing is completed within the browser, and input data is not sent to the server (even URLs containing confidential information can be used safely).
How to Use
Enter data
Select the "URL" or "Wi-Fi" tab and enter the content you want to encode. In the case of a URL, a link will be automatically generated.
Customize
Adjust the QR code color, background color (or transparency), storage size, and error correction level to your liking.
Save
Check the preview and press the "Save" button at the bottom right to save it to your computer or smartphone in PNG image format.
Glossary
- QR Code (Quick Response Code)
- A two-dimensional matrix barcode invented in 1994 by Denso Wave. Designed for high-speed component scanning, it now bridges the physical world with digital URLs.
- Error Correction Level
- A built-in fallback system using Reed-Solomon algorithms. Allows a QR code to be readable even if dirty or damaged. Available in 4 levels: L (7%), M (15%), Q (25%), and H (30% restoration capability).
- Finder Patterns
- The three prominent square structures at the corners of a QR code. They allow the scanner to instantly calculate the code's orientation and size regardless of camera angle.
- SVG Format
- A Vector graphic format that can be scaled infinitely without any pixelation or quality loss. Highly recommended when exporting the code to use in Adobe Illustrator or commercial printing.
- Margin (Quiet Zone)
- The mandatory blank area surrounding the matrix. Scanners rely on this contrast buffer to isolate the code from the surrounding physical environment or design.
- Transparent PNG
- An image export mode where the white background is stripped out, leaving only the black (or colored) blocks. Great for embedding directly into existing branded documents.
- vCard
- An electronic business card standard format. By selecting the vCard generation option, the output QR code will prompt mobile phones to automatically instantly save your contact details to their address book.
FAQ
- Q. Is it completely free for continuous commercial distribution?
- Absolutely. The QR codes you generate here contain no trackers, hidden limits, or subscription paywalls. You can print millions of them to sell without attribution.
- Q. Will these QR codes ever "expire" or stop working?
- No. These are "Static" QR codes. The direct data (URL or Text) is permanently hardcoded into the mathematical pattern mechanism. They will last infinitely forever as long as your destination URL functions.
- Q. Why did the pattern suddenly get overwhelmingly dense?
- Data capacity rules dictate that the more text or longer URLs inserted into it, the denser the grid matrix becomes. Try utilizing short URLs when printing physically on small labels.
- Q. Can I invert the colors or pick custom branding?
- You can select custom colors. However, scanning physics dictate that the "dots" must absolutely be darker than the background. Failing this contrast rule renders codes un-scannable on many devices.
- Q. How can I insert my company brand/logo perfectly in the center?
- Select Error Correction Level "H" (30%), save as structural SVG, and comfortably use external vector apps to overlay an opaque logo on the center space since 30% damage is algorithmically ignored.
- Q. Are you compiling history tracking data when scanned?
- We embed absolutely zero tracking pixels. Because they are static, any analytics measurement requires you to explicitly add Google UTM parameters to your URL string before generating.
- Q. Does it work offline without Wi-Fi?
- Yes. Since our architecture relies on lightweight JavaScript logic running strictly inside your loaded browser window, no connections to encoding servers are ever made or requested natively.
