Annotations made easy
Share comments on files, documents, and images. No extra software needed.
Share comments directly on files
Dropbox allows you to comment on any image or text preview—including Excel, Photoshop, and Sketch files—even if you don’t have the apps. Plus, there’s no need to download an image annotation tool—just click anywhere on an image or document file to leave an annotation on a specific region. You can leave comments on files on both desktop and mobile.
Annotate PDFs in Acrobat on any device
Our Adobe Acrobat integration makes working with PDF documents simple. Open any PDF stored in your Dropbox account in Adobe Acrobat, and you can annotate or highlight text in a PDF from any device. When you edit a PDF, changes are automatically saved to your Dropbox, and you can easily share the updated version with your co-workers.
Exchange feedback in real time
Eliminate the need for messy email threads full of follow-up questions on project feedback. With Dropbox file activity, you’ll always get notified when someone’s left a comment on one of your files—even if they haven’t tagged you specifically—so you can jump directly into the conversation.
