QR Code Generator for structured payloads and image download
Choose a payload type, review the generated content, and download a PNG or SVG QR image.
- Text, URL, Wi-Fi, PIX, and contact modes
- Configurable size, margin, and colors
- Error-correction levels
- PNG and SVG downloads
- Generated-payload preview
Generate QR codes for text, URLs, Wi-Fi, PIX, and contacts
Choose a format, fill in the required data, and generate a QR code with validation, an immediate preview, and PNG download.
Enter a valid URL, including a protocol such as https://.
The payload used by the QR code will appear here.
Correct the highlighted fields to generate the QR code.
Build the payload and generate the QR code immediately
- 1. Choose text, URL, Wi-Fi, PIX, or contact.
- 2. Fill in the fields required by the selected format.
- 3. The tool validates the data and builds the payload in real time.
- 4. Download the PNG QR code for digital or printed material.
Review the content before distributing the QR code
- Prefer short, trusted URLs to improve reading and scanning.
- Test PIX, Wi-Fi, and contact codes on more than one device before publishing.
- Avoid unnecessarily long payloads.
- Use strong contrast when placing the PNG in visual materials.
Turn known content into a scannable image
Use this generator to share a short text, web address, Wi-Fi access details, PIX data, or a contact card without requiring someone to retype it.
- Choose the mode that matches the format expected by the reader.
- Review the content before distributing the printed or digital image.
- Use the preview to adjust size, margin, contrast, and error correction.
How to create and review a QR code
- 1. Select Text, URL, Wi-Fi, PIX, or contact.
- 2. Fill the required fields for that mode; optional fields enter the payload only when provided.
- 3. Check the preview and represented content before downloading.
- 4. Download PNG or SVG and test it at the size and background where it will be used.
The QR code represents a specific payload
The QR library receives a string and turns it into an image. The string format changes with the selected mode.
Text and URL
Text stores exactly what you enter; URL requires a value accepted by URL and keeps the entered address.
URL validation does not visit the address or confirm its destination.
Wi-Fi and contact
Wi-Fi uses the WIFI format with SSID, password, encryption, and visibility; contact uses a vCard 3.0 card.
Structured fields escape special characters before the payload is assembled.
PIX
PIX builds an EMV payload with key, name, city, and optional amount and identifier.
The payload includes CRC16 for the format, but this does not confirm a payment or key ownership.
A text QR code
In Text mode, enter order-123. The string passed to the QR library is exactly that text.
order-123
order-123
The image changes with size, margin, and colors, but the represented content remains order-123.
Representing content is not verifying it
The code represents the content you provide; the tool does not verify security, ownership, or link destinations.
- A valid URL can lead to a wrong, malicious, or later-changed site; the tool does not open or audit it.
- A QR code does not hide data: anyone who scans it can read the payload supported by the mode.
- Contrast, margin, size, printing, and camera affect scanning; test the final image.
Review before sharing
Avoid placing passwords, keys, personal data, or payment details in an image that will be distributed without control. A QR code makes the content easy to copy.
Frequently asked questions
Does a valid URL mean its destination is safe?
No. The tool checks whether the text can be interpreted as a URL, but it does not visit, audit, or guarantee the destination.
Does a Wi-Fi QR code reveal the password?
The Wi-Fi payload includes the password when you provide one. Anyone who obtains and scans the code can recover that content supported by the format.
Does the PIX CRC confirm a charge?
No. CRC helps check payload integrity for the EMV format, but it does not confirm payment, key ownership, amount, or operational validity.
Does a QR code encrypt the text?
No. It encodes content into an image; it is not encryption and does not replace access controls.
How can I improve QR scanning?
Use clear contrast, keep the surrounding margin, avoid distortion, and test the PNG or SVG at its final size with a real scanner.
