How to generate a QR code
- Enter your text or a complete URL, including
https://for a website. Try sample fills inhttps://mytool0.com/. - Choose the size and colors. Start with margin 4 and error correction M for the example below.
- Select Generate QR code, then Download PNG or Download SVG. Both formats are free and require no account.
- Read the downloaded PNG with the QR Code Reader, and compare the decoded text with what you entered.
A downloadable example
This code contains https://mytool0.com/, uses dark modules on white, margin 4, error correction M, and a 512-pixel export. Use it to try the download-and-read workflow before making your own code.

PNG is convenient for documents and screens when you keep enough pixels for the intended size. SVG scales without raster blur and suits design software that accepts vectors. The reader accepts PNG, JPG, and WebP; to check an SVG in a finished design, export that design as PNG first.
Static QR codes and expiry
The downloaded image stores the text directly. MyTool0 does not put a subscription, expiry date, tracking service, or editable redirect between a scanner and your URL. The code itself does not time out, but the linked domain or page can stop working. Changing the encoded URL requires generating and distributing a new image.
Verify the destination before styling
For URLs, scan a plain first version and confirm the complete decoded destination before placing the code into artwork. Check the HTTPS scheme, domain, path, query parameters, and any redirects. A visually perfect QR code that points to the wrong page is still unusable.
The QR printing and testing checklist covers the full pre-publication workflow.
Keep contrast and quiet space
Dark modules on a light background are the safest default. Low-contrast brand colors can look attractive but become difficult to scan under poor lighting or after printing. Keep a clear margin around the matrix; do not let a later crop, border, or nearby text consume that quiet zone.
Error correction is a density trade-off
Higher error-correction levels add redundancy, which can help when part of a code is damaged or obscured. They also increase the amount of encoded structure for the same payload. Choose the level for the real environment rather than automatically selecting the highest option.
Longer content also makes a QR code denser. If a printed code is becoming too small to scan reliably, shortening unnecessary payload content can be more effective than squeezing the same matrix into fewer millimeters.
Test the exported artifact
The preview is only one step. Download the final PNG or SVG, place it in the actual poster, card, label, or screen layout, and scan that final composition from the expected distance. Test more than one device when the code matters operationally.
If you receive a QR image and want to inspect it, use the QR Code Reader in a supported browser.
Privacy
Generation happens in the current browser tab. The entered text or URL is not uploaded to a remote QR-generation service. As with any web page, loading MyTool0 still involves ordinary requests for the site itself; see the browser-local privacy guide.
