Once you’re inside the Trello board, locate the card where you want to attach the file. Click on the card to open it.

Step 3: Click on the “Attachment” section

Within the opened card, you’ll see various sections such as “Description,” “Checklist,” and “Comments.” Look for the “Attachment” section and click on it. This will open up the attachment options.

Now, it’s time to choose the file you want to attach. You have multiple options here:

  1. From your computer: Click on the “Attach a file” button and browse through your computer’s files to select the file you want to attach. Once you’ve selected the file, click “Open” to proceed.
  2. From Google Drive or Dropbox: If your file is stored in Google Drive or Dropbox, click on the corresponding button and sign in to your account. Then, choose the file you want to attach and click “Attach” to proceed.
  3. From a URL: If the file is hosted online, you can also attach it by entering the URL of the file in the provided field. After entering the URL, click “Attach” to proceed.

Choose the option that best suits your situation and preferences.

Step 5: Add a description (optional)

Once you’ve attached the file, you can add a description to provide more context or specify any instructions related to the attachment. This step is optional but can be helpful for your collaborators.

Step 6: Save the attachment

After attaching the file and optionally adding a description, click the “Save” button to finalize the attachment. The file will now be visible in the “Attachment” section of the card.
