When you share documents via a link, the first question is often: what file types can I upload? Sendpaper supports PDFs, Microsoft Office and OpenDocument formats, spreadsheets, presentations, images, video, and more. This page matches the logic in the product: the tables below show exactly which formats are supported, which you can view in the browser, and how support varies by plan.

File types and extensions (reference)

Use this table to see exact extensions and whether each category is viewable in the browser or download-only.

What “in-browser” vs “download only” means

In-browser preview: The viewer opens the link and sees the document (or plays video/audio) without downloading. PDF, Word, PowerPoint, spreadsheets (within size limit), images, and CAD are rendered as pages or media in the viewer. Same access control and analytics apply.

Download only: The file is not rendered in the viewer. The recipient gets a secure, trackable download. Used for RTF, TXT, archives, KML, KMZ, MSG, and spreadsheets over 20 MB. Access control and link analytics still apply.

Preview inside the secure viewer

Sendpaper renders many uploads in the secure viewer so recipients can preview and play without downloading first. For example, PDFs are commonly converted into page images so the UI can display them reliably.

Your browser does not support the video tag.

PDFs converted into viewer-ready page images (fast, consistent preview).

Video preview in the viewer

Your browser does not support the video tag.

Audio preview and tracking inside the secure Sendpaper viewer.
