Public PDF Link Checker

"I shared the link" is not the same as "it's public"

Google Drive, Dropbox, OneDrive, and SharePoint all have sharing settings that are easy to get wrong. A link that works for you — because you're logged into the same Google account — may show a permission error to anyone outside your organization. The only way to know is to test the URL from a fresh session, which is what PrintLink Checker does.

Common failure modes for PDF links on print materials: the document was shared with "anyone with the link" but later restricted; the Google Drive folder was moved; the Dropbox account was downgraded to a free tier and public sharing was disabled; or the link is to a SharePoint document that requires organizational credentials to view.

If your PDF is large, also check the load time. A 15MB unoptimized catalog PDF linked from a flyer QR code will frustrate every mobile visitor who tries to open it on the go. Consider using a direct CDN-hosted link or an optimized PDF rather than a cloud drive share.

PDF link checklist before printing

• ✓
  Link opens without a login prompt — Test from an incognito window or a different device. Drive and Dropbox links often work only for signed-in users.
• ✓
  File downloads or previews successfully — Confirm the PDF actually renders — not just that the URL resolves.
• ✓
  HTTPS is valid — Cloud storage providers use HTTPS, but verify for direct-hosted PDF links.
• ✓
  File size is reasonable for mobile — PDFs over 5MB load slowly on mobile. Optimize before linking.
• ✓
  Sharing settings are permanent, not expiring — Some Drive share links can be revoked by the owner or expire. Prefer a direct hosting URL for print materials.
• ✓
  Correct version of the file — Confirm the link points to the final version — not a draft you shared during review.
