By Impran M N
Keeping project files scattered across email and desktop folders makes it hard for your team to find what they need. This guide covers the different ways to attach files directly to a Trello card, from drag-and-drop to linking cloud storage.
01Open a task card
Click a specific card on your board to expand its detailed back panel.
02Find the attachment option
In the right sidebar, locate the Actions menu and click the Attachment button.
03Upload a local file
Select 'Choose a File' to browse your computer and pick the document you want to attach.
04Drag and drop instead
Alternatively, drag a file directly from your desktop and drop it anywhere over the open card.
05Link a cloud file
Paste a shared document URL, such as a Google Drive or Dropbox link, into the attachment input box.
06Set a cover or rename a file
Click 'Make Cover' next to an image attachment to use it as your card's visual cover, or click Edit to rename an existing attachment.
Frequently asked questions
Can I attach files from Google Drive or Dropbox?
Yes, you can paste a shared cloud document link into the attachment box to link the file without uploading it directly.
Does uploading a file use up my workspace storage?
Local uploads do count against storage, while linking a cloud file preserves your workspace storage allocation.
Can I turn an attached image into the card's cover photo?
Yes, click the 'Make Cover' toggle next to an uploaded image to set it as the card's visual cover.
How do I remove an old attachment?
Click the Delete trigger next to the file row to remove a stale attachment and keep your card history clean.
