Frequently asked questions
Which file format should I use for printing?
SVG or PDF scale to any size without quality loss, so they're the safer choice for print; PNG/JPEG are fine for screens.
Does the QR code expire?
No — it always points to the same username link, so it keeps working as long as the username itself does.
