How To Add A File To Trello Board

Trello is a popular project management tool that allows users to create boards and cards to organize tasks and ideas. One of the great features of Trello is the ability to attach files to cards, making it easy to share documents, images, and other resources with team members.

Step 1: Open Trello

To add a file to your Trello board, you’ll first need to open the app or log in to the website. Once you’re logged in, navigate to the board where you want to add the file.

Step 2: Create a Card

If you haven’t already created a card for the task or idea you want to attach the file to, now is the time to do so. Click on the “Add Card” button in the top right corner of the screen and give your card a title.

Step 3: Attach the File

Once you’ve created the card, click on the “Attach” button in the bottom left corner of the screen. This will open a file upload window where you can select the file you want to attach from your computer or device.

Step 4: Add a Description

After attaching the file, you may want to add a description or comment to provide more context for the attachment. Click on the “Comment” button in the bottom right corner of the screen and type your message.

Step 5: Save Your Changes

Finally, click on the “Save” button in the top right corner of the screen to save your changes. The file will now be attached to the card and visible to all members of the board.


Adding a file to Trello is a simple process that can help you keep your team organized and on track. By following these steps, you’ll be able to attach files to cards quickly and easily, making it easy to share resources with your team members.
