QR and barcode tools FAQ
Are my QR and barcode details uploaded?
No. Generation and image decoding run locally in your browser. Rabetly does not receive the content, passwords, contacts, or files you enter.
Can I download PNG and SVG files?
Yes. Each generated QR code and barcode can be downloaded as a PNG or SVG file. SVG is usually best for printing.
Is it safe to open a decoded QR link?
Treat decoded values as untrusted. This reader shows the full value as text and never opens a link automatically.
