1. Automated Bates Numbering
Legal professionals have long used Bates numbering to index large document collections, but this feature has become more powerful in 2025:
- Dynamic numbering: Automatically apply sequential numbers with custom prefixes/suffixes
- Metadata integration: Include case numbers, dates, or other metadata in your stamps
- Batch processing: Number thousands of pages across multiple documents simultaneously
Pro Tip: Use our PDF Merger with the "Add Sequential Numbering" option to automatically apply Bates numbering when combining legal documents.
2. Professional PDF Portfolios
Modern PDF portfolios go far beyond simple file collections:
- Custom interfaces: Create branded navigation with your company logo and colors
- Mixed content: Combine PDFs, Word docs, Excel sheets, and images in one package
- Search functionality: Enable full-text search across all included documents
Portfolios are perfect for client deliverables, project submissions, and sales proposals.
3. Smart PDF Forms with Calculations
2025's PDF form capabilities rival dedicated form builders:
- Auto-calculating fields: Create forms that automatically total values or perform complex calculations
