# PDFs

> Drop a PDF onto a canvas and you get a card showing its first page and how many pages it has. Click it to open a full-screen viewer that scrolls through the whole document and offers a download. Free accounts can upload PDFs up to 50 MB; Creator removes the cap.

A PDF on a board is a real document, not a download link.

## The card

Dropping a PDF gives you a card showing the **first page** as a thumbnail, plus
the **page count**. At a glance you can tell a two-page treatment from a
ninety-page script.

The card behaves like any other — move, resize, group, tag, comment, put it in a
[grid](/docs/canvas/grids) cell.

## The viewer

Click the card to open full screen. The viewer scrolls the whole document and
renders pages as you reach them, so a long PDF opens immediately rather than
after processing every page.

**Download** is in the viewer, and gives you the original file untouched.

## What you cannot do

The PDF is not editable in place. There is no in-document annotation, no form
filling, no page reordering.

What you can do instead:

- **Draw on the canvas** over the card — see [Shapes and drawing](/docs/canvas/shapes-and-drawing)
- **Comment on the card** — see [Comments](/docs/collaborate/comments)
- **Put a note beside it** with the feedback

## Size limit

Free accounts cap PDFs at **50 MB**. Creator removes the
cap. See [Plans](/docs/account/plans).

A script or a treatment is comfortably under that. A print-resolution deck with
embedded images often is not.

## Making PDFs

Clusters produces PDFs as well as reading them:

- A whole board — [Exporting a board](/docs/canvas/export)
- A document — [Exporting documents](/docs/documents/export)
- A [screenplay](/docs/documents/screenplay) in correct industry format, where the on-screen pages match the PDF pages exactly
