Attach files to a card

last updated at: Sep 13, 2026

A card can carry files: a screenshot of the bug, the PDF you are reviewing, the document the work is written in. Everyone with access to the board can open them. You need write access to add one.

Attach a file

  1. Open the card and click the pencil icon (Edit), or start a new card with Add a sticky.
  2. Click the paperclip button (Add attachment) in the bottom-left corner of the dialog.
  3. The Attach file dialog opens on your Drive. Click the file you want, or hold Shift or Ctrl (Cmd on a Mac) to pick several.
  4. Click Select. The button shows a count, such as Select (2), when you pick more than one.
  5. The files appear as chips in the dialog. Click Save, or Add Sticky on a new card, to attach them.

To use a file that isn't in Drive yet, click Upload from device at the bottom of the Attach file dialog and pick the files in the chooser that opens.

You can also drag files from your desktop straight onto the open dialog, or paste an image you have copied. Both add a chip the same way.

Nothing is attached until you save the card. Cancel leaves the card as it was.

What gets copied and what gets linked

A document, spreadsheet, presentation, or other Eigen file attaches as a link rather than as a copy. Its chip reads Open [filename] and opens the file in a new tab, and the other person needs access to that file to open it.

Everything else, such as a PDF or an image, is attached as a copy, so it stays with the card even if the original in Drive changes or goes away.

Remove an attachment

Open the card and click the pencil icon (Edit), then click the X on the chip of the file you want to take off. Click Save. The rest stay attached.

What the card shows

Attachments give the card face two things you can read at a glance:

  • Attach an image, and the card shows it as a cover picture across the top.
  • A paperclip icon with a number tells you how many files are on the card.

Open an attachment

Click the card to open it. The chips sit below the description. Click one to open a preview of the file.
