Host your PDF anywhere — Google Drive (use the "anyone with link" share URL), Dropbox, your own server, S3, etc. Paste the public link here. We encode the URL so the QR works forever and never depends on us. Tip: for Google Drive, replace /view in the share URL with /preview for a cleaner mobile view.

Paste your form's share link — either the short forms.gle/… or the long docs.google.com/forms/d/e/…/viewform form. We auto-prefer forms.gle when both are available since the shorter URL produces a denser QR. Works for surveys, registrations, RSVPs, lead capture, classroom polls.
