How Big Attachment Can I Upload To Trello

Trello is a popular project management tool that allows users to collaborate and organize tasks. One of the key features of Trello is the ability to attach files to cards, which can be useful for sharing documents, images, and other resources with team members. However, there are limitations on the size of attachments that can be uploaded to Trello.

File Size Limits

The maximum file size limit for attachments in Trello is 10MB. This means that any files larger than 10MB will not be able to be uploaded to Trello. It’s important to keep this in mind when attaching files to cards, as attempting to upload a file that exceeds the limit will result in an error message.

Alternatives for Large Files

If you need to share a file larger than 10MB with your team members, there are several alternatives available. One option is to use a cloud storage service like Google Drive or Dropbox, which allow users to upload and share files of any size. Another option is to use a file sharing service like WeTransfer or Hightail, which allow users to send large files directly to recipients via email.


In conclusion, while Trello’s attachment feature can be a useful tool for sharing resources with team members, it’s important to keep in mind the 10MB file size limit. If you need to share a larger file, there are several alternatives available that can help you get the job done.
