# PDF for Confluence FAQ The questions below come from support conversations and from the edge cases in the product. Each answer links to the page with the detail. --- ### Can signed-out readers see an embedded PDF? No. Readers who are not signed in see **Sign in to view this PDF** for an attachment, or **PDF unavailable** for a link, even on a public page. See [this troubleshooting page](https://help.gocapable.com/pdf-embed/signed-out-readers-on-a-public-page-see-sign-in-to-view-this-pdf-or-pdf-unavailable-instead-of-t.html). ### What is the largest PDF I can embed? A PDF linked from a website can be up to 2.5 MB. An attached PDF has no Capable limit beyond your site's attachment size limit. See [Embed a large PDF in Confluence](https://help.gocapable.com/pdf-embed/embed-a-large-pdf-in-confluence.html). ### Can I paste a PDF link into the editor to embed it? No. Insert the **PDF embed (Capable)** macro first, then paste the link into **PDF URL**. See [Embed a PDF from a URL in Confluence](https://help.gocapable.com/pdf-embed/embed-a-pdf-from-a-url-in-confluence.html). ### Do I need an account, sign-in or API key? No. Attachments are read with each reader's Confluence permissions, and public links through Capable's proxy. See [No external account](https://help.gocapable.com/pdf-embed/no-external-account.html). ### Does the embed update when I upload a new version of the PDF? Yes, for an attachment: upload a new version of the same attachment and the viewer shows it. A linked PDF shows whatever the website serves now. ### Can I embed a password-protected PDF? No. The viewer shows **This PDF is password protected**. Remove the password, or attach an unprotected copy. See [this troubleshooting page](https://help.gocapable.com/pdf-embed/this-pdf-is-password-protected.html). ### Why are the layout, download and other options missing from the configuration? They appear only once the macro has a PDF. Choose the file or paste the link first. See [this troubleshooting page](https://help.gocapable.com/pdf-embed/none-of-the-display-options-layout-height-download-popup-fullscreen-text-layer-appear-in-the.html). ### Why will zoom not go past 200%? Zoom runs from 20% to 200%. Use **Fullscreen** for a bigger view. See [Zoom will not go beyond 200%, or below 20%](https://help.gocapable.com/pdf-embed/zoom-will-not-go-beyond-200-or-below-20.html). ### Does the PDF appear when I export the page to PDF or Word? No. Confluence's export leaves a gap where the embed was. Attach the PDF as well if readers of the export need it. See [this troubleshooting page](https://help.gocapable.com/pdf-embed/exporting-the-confluence-page-to-pdf-or-word-leaves-a-gap-where-the-embed-was.html). ### Does it work on a published Capable Site? Yes. The document is copied into the site. Zoom, Slider page navigation and **Download** carry over; pop-out, fullscreen and selectable text do not. See [Capable Sites export](https://help.gocapable.com/pdf-embed/capable-sites-export.html). ### Why do some readers see "You cannot view this PDF"? They do not have Confluence permission to view the attachment. Check the page's restrictions. See [this troubleshooting page](https://help.gocapable.com/pdf-embed/some-readers-see-you-cannot-view-this-pdf-you-do-not-have-permission-to-view-this-attachment.html). ### Is the macro the same in the Capable Suite and the standalone app? Yes, the macro and its settings are identical. The Suite also lets an administrator approve PDF websites under **Egress domains**. See [Suite or standalone](https://help.gocapable.com/pdf-embed/suite-or-standalone.html). --- ## Related ### [Embedding PDFs in Confluence](https://help.gocapable.com/pdf-embed/embedding-pdfs-in-confluence.html) Attachment, link or upload. ### [PDF viewer settings in Confluence](https://help.gocapable.com/pdf-embed/pdf-viewer-settings-in-confluence.html) Layout, page, buttons and text. ### [Troubleshooting](https://help.gocapable.com/pdf-embed/troubleshooting.html) Every known problem. --- _Short answers, with the detail one click away._
