PDF to QR code for teachers: share worksheets and answer keys
Put a worksheet PDF behind a QR code on paper or a slide. Students open it without signing in, you can swap the file, and answer keys wait until you're ready.
Publish the form, turn the responder link into a dynamic QR code, stop forced sign-ins, reuse the code next round and compare scans with responses.

In Google Forms, click Publish first, then copy the responder link and paste it into the Google Form QR code page. Press "Create QR code" and download the image. Before you print, scan it with a phone that is not signed in to Google: if the questions open straight away, anyone can answer; if a sign-in page appears, fix the settings described below first.
Forms now have to be published before anyone can respond. An unpublished form stays closed even to people who have the link, as Google's Forms help explains.
Do not copy the address bar while you are editing the form (the link ending in /edit). That link is for editors, not responders.
Scanners first see a short qrfast landing page with the QR name, the destination domain, a safety check result and an ad, which is how the service stays free. They tap "Continue to docs.google.com →" to reach the form. Owners cannot turn this page off.
If the form uses any of these settings, people who scan with a phone that is not signed in to Google must sign in before they can answer:
If you use a school or work account and cannot open the form to anyone with the link, your administrator may have blocked responses from outside the organization. Google added these admin settings for Google Workspace in mid-2025, so ask your IT team.
To test, open the responder link in a private browser window, or scan the code with someone else's phone. If the questions appear with no sign-in page, you are ready.
The code points to a qrfast short link, not to the form itself, so you can swap the form without reprinting.
Between rounds you have two options:
For limited places, such as 40 seats, Google Forms can close itself: under "Accepting responses", choose Set close date or response limit. Google notes that responses arriving at exactly the same time can go over the limit (View & manage form responses), so leave some margin.
Three numbers show where people drop off:
Two things to keep in mind. Scans count visits, not people: one person scanning twice counts twice (bots are not counted). And if you also share the form link elsewhere, such as in a group chat, the responses include people from that channel. A free account adds 30- and 90-day statistics by country, device, operating system and time of day, plus CSV export.
Yes. Paste that form's link into the website link type. Editing the destination and scan statistics work the same way; sign-in rules depend on that tool's settings.
Members can use Bulk from CSV in the dashboard: a two-column file (title, destination) of up to 200 rows creates a full set of link codes, each editable later.
Yes. qrfast dynamic codes do not expire unless the destination breaks our usage policy, in which case the code is suspended. Point the code at next year's form when it is ready.

Dynamic QR codes can be edited and tracked but depend on a service and show a landing page with ads. Static codes never change and depend on no one.
Enter the network name, password and security type exactly as on your router. iPhone and Android cameras can scan it. A new password needs a new code.
