About QR code generator
Use this QR code generator online to share a link or a short text payload. You can create a QR code for a URL and download it as a PNG without a redirect service. The encoded destination is part of the image and cannot be changed after printing it.
How to create a downloadable QR code
- Enter the exact text or complete URL to encode.
- Choose an image size between 128 and 2048 pixels and select Process.
- Download the PNG and scan it with a separate device before publishing.
A practical example
- Input
https://yyytools.com; Image size: 512.
- Result
qr-code.png containing the supplied URL at the selected image size.
Test the final printed or displayed size. Long payloads create denser codes and may need a larger image.
Supported input and limitations
- Content is limited to 3,000 characters and may reach QR encoding capacity sooner depending on its characters.
- This creates static PNG codes, not editable dynamic codes, scan analytics, custom logos, or SVG exports.
Processing happens on your device. Read about local processing and optional workspace recovery.
Frequently asked questions
Do generated QR codes expire?
The static image has no service-controlled expiry. A website linked by the code can still move, become unavailable, or require access.
Can I change a QR code's URL after downloading?
Not inside an existing static code. Generate a new image, or control a redirect at the URL you originally encoded.
