Group text and attachments in task comment

Users can include a block of text and one or more attachments grouped together. Attach a file or attach an image and comment seamlessly.


This streamlines comments that contain both text and attachments.

Attachment limits

There is a 100MB per file limit for attachments from your computer. If you have a larger file, consider attaching it from Dropbox or Google Drive.

There is no storage limit for the number of files you can upload.

Attachment integrations

You can attach files from BoxDropboxGoogle Drive or Microsoft OneDrive/SharePoint directly into Asana tasks.

Each of these integrations have their own set of permissions associated to their files. Our integration does not change your files' permissions whatsoever, so you may also need to share the file with your colleagues after attaching it to a task.

  1. Click the paperclip icon
  2. Select one of the three options and a new window will popup allowing you to log into that respective account. Login and choose the file you wish to attach.

If you are logged in to multiple Google accounts on your computer, you can select which Google Drive account to attach files from, regardless of which Google account is currently associated to your Asana account.

Via email

You can attach files when you create tasks by email.   Please note that you can only forward emails to Asana with a max. total of 30 MB

From the drop-down arrow in the attachment's name you have three options: Request approvalDownload attachment and Delete attachment.

Choose Delete attachment if you wish to delete.

Removing the thumbnail for an image or the story for an attachment from the activity feed will not remove the file from the task. The activity feed is a list of timestamped actions above the comments field.

Connected work links

Connected work links provide context and access to related work enabling your team to move fast. Connected work links serve as a visual indicator that an object (tasks, status updates, messages etc.) have been referenced (@ mentioned) elsewhere in Asana. These links are automatically created whenever a user @ mentions a task, status update, message or goal in Asana and will appear in the activity feed of the object that has been mentioned. This helps your team to communicate more reliably and with less effort highlighting where important connections between work already exist, helping teams to see and open objects that they otherwise might have missed. Connected work links are tagged with a ↔ symbol and can only be seen by users who have access to the object that has been @ mentioned. Users who don’t have access will not see anything.

There is no limit to the number of connected work links that can appear in the activity feed. Clicking on a specific connected work link will bring you the task, status update, message, or goal in Asana that has been @ mentioned. Just like other items that appear in the activity feed, connected work links can be deleted manually.
