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. PDFs up to 50 MB open in the viewer; a larger one lands as a file card with a download. There is no PDF size limit on any plan.
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.
A PDF whose first page couldn't be drawn as it arrived, or that came in from a message or the API, gets it the next time someone who can edit opens the cluster. A password-protected PDF keeps the PDF mark.
The card behaves like any other — move, resize, group, tag, comment, put it in a grid 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
- Comment on the card — see Comments
- Put a note beside it with the feedback
Size
There is no PDF size limit on any plan — a PDF counts toward your storage like any other file. Up to 50 MB it becomes a PDF card that opens in the viewer; a larger one lands as a file card with a download, so a print-resolution deck with embedded images still comes along whole.
Making PDFs
Clusters produces PDFs as well as reading them:
- A whole board — Exporting a board
- A document — Exporting documents
- A screenplay in correct industry format, where the on-screen pages match the PDF pages exactly
Frequently asked questions
Can I annotate a PDF?
Not inside the document. You can draw on the canvas over the PDF card, and attach comments to the card, but the PDF file itself is not edited.
Does the viewer load the whole file at once?
No. Pages render as you reach them, so a long document opens immediately instead of waiting for every page.
Can I turn a PDF into images?
Not automatically. Export the pages you want from your PDF tool and drop them in as images if you need them as separate cards.
