Download Restriction

Download restriction is a security setting that prevents readers from saving or downloading the original PDF file behind a published flipbook or document. When enabled, the download button is disabled or hidden entirely from the viewer toolbar. Readers can still view and interact with the content in the browser — flipping pages, zooming in, searching text — but the source file remains on the server and is never transferred to the reader's device as a standalone file. This gives publishers control over how their content is consumed and distributed.

Many publishers need to share content without giving it away. Once a PDF is downloaded, it can be forwarded to unauthorized recipients, uploaded to file-sharing sites, edited to remove branding, or printed and distributed in bulk — all without the publisher's knowledge or consent. Download restrictions close this gap by keeping content within a controlled viewing environment. Publishers also benefit from sustained [analytics](/glossary/analytics-dashboard) data, since readers must return to the published link each time they want to access the content, generating accurate engagement metrics with every visit.

FlipLink's [Privacy & Access Control](/features/privacy-and-access-control) settings let you toggle download permissions on or off for each publication independently. When downloads are restricted, the PDF download option is removed from the viewer toolbar. Readers can still flip through pages, zoom in, use the table of contents, and interact with all other viewer features — but they cannot extract the original file. You can change this setting at any time without generating a new share link, and different publications can have different download policies based on their sensitivity or business purpose.

Download restriction is not always the right choice. Here are the scenarios where it adds the most value: - **Paid or premium content**: Course materials, research reports, and proprietary guides that readers pay to access. Allowing downloads undermines the pricing model. - **Pre-release or confidential documents**: Draft reports, internal proposals, or embargoed research that should not circulate beyond the intended audience. - **Lead-gated content**: Whitepapers and ebooks offered in exchange for contact information. If readers can download and share the file, the [lead capture](/glossary/lead-capture) gate loses its purpose. - **Branded catalogs and menus**: Content where you want readers to always see the latest version at your published link rather than referencing an outdated downloaded copy. When downloads serve your goals — for example, a free resource meant to be widely shared — leave them enabled to maximize distribution.

**Combine with other access controls.** Download restriction works best as part of a layered security approach. Pair it with [password protection](/glossary/password-protection) to restrict who can view the content, [link expiry](/glossary/link-expiry) to limit how long access lasts, and [domain whitelisting](/glossary/domain-whitelisting) to control where the flipbook can be embedded. **Set expectations with your audience.** If readers expect to download a file and find the option missing, they may contact you for support. Add a note on your landing page or within the flipbook itself explaining that the content is view-only for security reasons. **Use selective restrictions.** Not every publication needs download protection. Apply it to sensitive or monetized content and leave downloads enabled for marketing materials you want widely distributed. FlipLink lets you configure this per publication, so you can tailor the policy to each use case. **Review restrictions periodically.** Content that was confidential during a product launch may become freely distributable six months later. Revisit your download settings when the business context around a publication changes.

A professional certification body publishes its exam preparation guide as a FlipLink flipbook with download restrictions enabled. Enrolled candidates receive a share link and can study the guide online at any time, but they cannot save the PDF locally or forward it to non-enrolled peers. When a candidate completes their certification, the body can revoke access using link expiry. This approach protects the intellectual property behind the study guide, maintains the value of the paid certification program, and gives the organization accurate data on which candidates are actively studying through page-by-page [analytics](/glossary/analytics-dashboard).
