How the tool works
Choose URL or text, enter the content, and customize the size, margin, and colors. The preview updates in your browser and can be copied or downloaded without uploading the content.
Supported input and output
The generator accepts plain text and URLs and exports PNG and SVG. It automatically uses medium error correction, balancing scan resilience and visual density for general use.
Practical example
Enter a website address, keep a clear dark foreground on a light background, and download SVG for print or PNG for a document or social post.
Common use cases
Create QR Codes for printed material, menus, presentations, signs, product instructions, event information, links, and short text.
Limits and important checks
A QR Code does not verify that a link is safe or permanent. Low contrast, insufficient margin, small print size, or excessive content can make it difficult to scan. Test the final artifact before distribution.
Privacy and local processing
Unless the tool explicitly identifies an external lookup, input and generated output are processed in your browser and are not uploaded to CosmoTools. Avoid placing secrets in any web page and review downloaded results before using them in production.
Frequently asked questions
Is my content uploaded?
No. The QR Code is generated locally in your browser and the content is not sent to CosmoTools.
Which formats can I download?
You can download the generated QR Code as a PNG image or a scalable SVG file.
Why does contrast matter?
QR Code readers need a clear difference between foreground and background. Low contrast can make the code difficult or impossible to scan.
