Print once, update forever
A QR code on a menu, a brochure, or a shop window is expensive to reprint and impossible to recall. Point it at a FileDroppr link and the code never goes stale - you update the PDF, the paper stays where it is.
Everything persists
The short link, the QR code, the password, the email gate and lead form, the vanity slug on your custom domain - every setting rides through a replacement untouched. Only the pages change.
Version history, kept
Every version you replace is kept in the document's history, so you always know exactly what was live on any given day - useful when the document is a price list or a legal notice.
Readership per version
Each visit records which version it saw. When the funnel improves after an update, you can prove it was the new pages - not a different audience.
Printed QR codes that never go stale
Print is where a broken link hurts most: a QR code on a laminated table menu, a property brochure in a rack, signage in a window. The moment the document changes, a static code is a reprint job. A dynamic FileDroppr link inverts that - the code on the paper is permanent, and the PDF behind it is whatever you say it is today.
That is the daily workflow for restaurant QR menus - update the dishes, keep the table cards - and for real estate brochures, where the brochure behind the sign changes as the listing does. One code on the printed material, forever; the file swapped from your library in seconds.
What survives a replacement
- The URL and short link. Every copy of the link anyone ever saved, sent, or bookmarked now serves the new file.
- The QR code. Printed or on screen, the code is unchanged - it points at the link, and the link points at the new version.
- Protections and gates. Password, expiry, download policy, the email gate, lead capture forms, and the domain allowlist all carry over exactly as configured.
- Your domain and slug. A vanity slug on your custom domain keeps resolving - readers on docs.yourcompany.com never see a seam.
- Branding and viewer mode. Flipbook styling, your logo, the CTA button, the chosen reading mode - the presentation is part of the link, not the file.
Version history and per-version readership
Replacing a file is not overwriting it. FileDroppr keeps the version history, and the readership record notes which version every visit saw - so the reporting stays honest across updates. If page 3 stopped losing readers after Tuesday's revision, the funnel will show it, version by version.
That turns a dynamic link into an experiment you can actually read: ship a revised deck behind the same link you already sent, and compare how the new pages perform against the old ones with the same audience.
Replacing a file revives a burned link
A self-destructing link deletes itself when its view budget is spent - and normally that is the end of the story. Replacing the file behind it starts a new chapter: the link comes back to life serving the new version, with a fresh budget and the full readership record of its previous life intact. One-time delivery, repeatable.
How to replace the PDF behind a link
- Open the document in your library. Every FileDroppr document you own has a replace option alongside its sharing settings.
- Upload the new file. A PDF - or a Word .docx, which is converted on the way in. The old version moves into the history.
- Done - the link already points at it. No settings to redo, no QR to regenerate, nothing to resend. Readers who open the link now get the new pages.
Dynamic link questions.
What is a dynamic PDF link?
A dynamic PDF link is a share link whose underlying file you can replace without changing the URL. On FileDroppr, replacing the PDF behind a link keeps the short link, QR code, password, gates, and custom-domain slug exactly as they were - every existing copy of the link, printed QR codes included, serves the new version instantly.
Can I change the PDF behind a QR code without reprinting it?
Yes. The QR code encodes the link, not the file - so when you replace the PDF behind a FileDroppr link, every printed code that points at it serves the new document on the next scan. Menus, brochures, signage, and product inserts never need a reprint for a content change.
What happens to the old version when I replace a file?
It is kept in the document's version history rather than destroyed, and your readership record notes which version each visit saw - so you can tell how the document performed before and after any update, and what was live on a given date.
Do passwords, gates, and my custom domain survive a replacement?
Yes - all of it. The password, expiry, download policy, email gate, lead capture form, domain allowlist, branding, viewer mode, and any vanity slug on your custom domain persist through a replacement. Only the file changes.
Can replacing the file revive a self-destructed link?
Yes. A self-destructing link that has spent its view budget and deleted its file comes back to life when you replace the file behind it - the same URL starts serving the new version, and the readership record of the previous version survives.
Which plan includes dynamic links?
Replacing the file behind an existing link is a Pro feature ($29/month, or $290/year - two months free). Every plan can create links and QR codes; Pro adds replacement, version history, and per-version readership on top.
Put a permanent code on it.
Upload the document, print the QR once, and never let paper hold your content hostage again.
