How to Allow Reviewers to Attach Files in a Shared PDF Review
Product
Adobe Acrobat
Device & OS
not provided
Scenario
Collaborating on a PDF document where reviewers and clients must insert supplementary images or documents at specific locations within the PDF.
Observed behavior
Acrobat's cloud-based Share workflow limits reviewers to only five basic commenting tools, preventing them (especially those without Adobe accounts) from attaching files.
Before you start

Verify whether your PDF review is hosted on Adobe's cloud services or a local network, as cloud-based reviews inherently restrict advanced commenting features like file attachments.

Solution 1Recommended

Switch to a Traditional Network-Hosted Review Workflow

Bypass Acrobat's cloud sharing limitations by hosting the shared review on a local network folder or SharePoint server to retain full commenting capabilities.

Adobe's modern cloud-based review platform intentionally limits commenting tools to streamline the web interface. By using the traditional shared commenting feature hosted on your own internal server, you ensure all reviewers have access to advanced tools, including the ability to attach files directly to the PDF.

1
Open the PDF document

Launch Adobe Acrobat and open the PDF file you wish to send for review.

2
Access the Send for Comments tool

Navigate to the Tools menu and select 'Send for Comments' or 'Share', ensuring you bypass the default cloud-link generation.

3
Choose an internal server setup

Select the option to host the review on an 'Internal Server' or 'SharePoint' as your distribution method.

4
Send the invitation

Complete the setup and invite your reviewers. When reviewers open the file in their local Acrobat desktop application, the 'Attach File' tool will be available.

Frequently Asked Questions

Why are advanced commenting tools missing in Acrobat's shared review?

Acrobat's cloud-based share links offer a simplified interface designed for basic, streamlined feedback. Advanced tools like file attachments, custom stamps, and rich media are disabled in this cloud mode to ensure cross-browser compatibility.

Can a reviewer without an Adobe account attach files to a PDF?

In an Adobe cloud-hosted review, anonymous users or those without accounts face severe commenting restrictions. However, if you send the file directly via email or use a local network review workflow, anyone with a standard desktop PDF reader can attach files.

How do I view attached files inside a PDF document?

You can view attached files by opening the Attachments panel (usually represented by a paperclip icon on the left sidebar of your PDF reader) or by double-clicking the specific attachment pin icon located directly on the PDF page.
