PDF annotation tools for document review
Provide comprehensive annotation tools including highlights, shapes, text notes, stamps, and signatures to streamline document collaboration. Capture feedback, mark revisions, and track updates directly within PDF files to ensure clear, efficient review processes.
Highlight and mark PDF text
Mark selected PDF text with highlighting, underlining, strikethrough, or squiggly annotations to flag important passages. Use this feature to highlight key information and clearly mark text that requires attention, correction, or verification during document review.
Draw shapes and measure PDFs
Draw shape annotations and measurement tools directly on PDF pages to annotate layouts, designs, and spatial dimensions. Use this feature when you need to provide visual feedback about page layouts, verify measurements, or highlight specific areas during document reviews.
Add freehand sketches and text notes
Draw freehand sketches with ink annotations and add text annotations to capture ideas and feedback directly on PDF pages. Use ink and free-text annotations when visual context or custom notes are needed beyond traditional markup.
Add comments with sticky note
Attach sticky note comments to specific PDF locations to keep feedback connected to relevant content and discussion points. Use this feature when review discussions and decisions need to stay linked to exact document locations for greater clarity and context.
Sign and approve PDF documents
Add approval marks and digital signatures to PDF documents to show review status and confirm final decisions. Use this feature to document approval steps, establish audit trails, and maintain a clear record of who approved the document and when.
Customize annotation appearance and behavior
Tailor annotation appearance and behavior including colors, opacity, line styles, fonts, and stamps to match organizational standards. Use this feature to create consistent, branded annotation experiences that align with your review requirements and professional document standards.
Manage annotation review workflows
Keep document reviews organized by modifying markups, controlling permissions, undoing changes, and organizing feedback throughout the review lifecycle. Use this feature to support complex review processes with multiple contributors while maintaining clear, structured, and audit-ready collaboration.
Import and export PDF annotations
Preserve and share annotation data across teams and systems by importing and exporting annotation data. Use this feature to integrate PDF reviews with business workflows, streamline collaboration across departments, and maintain review history across multiple platforms.
