Which PDF editing software has the best collaboration features?

If your priority is collaboration, the best PDF software is usually Adobe Acrobat Pro.

Why Adobe Acrobat Pro stands out

• Shared review with comments and annotations
• Real-time collaboration on cloud-hosted PDFs
• Version tracking and review history
• Easy comment replies, mentions, and resolution workflows
• Strong integration with Microsoft 365, Google Drive, OneDrive, SharePoint, and Adobe cloud

Good alternatives

• Foxit PDF Editor — strong collaboration tools, often cheaper than Adobe
• Nitro PDF Pro — solid for team workflows, but collaboration is less advanced
• Kami — very collaboration-focused, especially for education and review-heavy teams
• Smallpdf / pdfFiller — convenient cloud collaboration, but less powerful for deep editing

Best choice by use case

• Best overall collaboration: Adobe Acrobat Pro
• Best budget option: Foxit PDF Editor
• Best for simple shared review: Kami
• Best for form/sign workflows: pdfFiller
