Export tips & privacy

PNG is a pixel image for slides, documents and online sharing. SVG is vector artwork that remains sharp at any size, ideal for printing. Both include a four-module quiet zone. QR codes are generated entirely in your browser; SciWrench does not receive or store the content you enter. Test the downloaded QR code with your phone before distributing it.

◈ Sharp at any scaleVector SVG plus PNG exports up to 4096 pixels for crisp print and digital use.

⌁ Private by designQR generation happens locally. No account, tracking of entered content, or server-side processing.
