PDF Page Merger
Insert selected pages from one PDF into another at an exact position.
The PDF Page Merger lets you combine documents with page-level control. Instead of appending an entire file, you can choose only specific source pages and insert them into a base PDF at a precise point. This is useful for building custom packets, revising briefs, and assembling client-ready files from multiple document sources.
What This Tool Does
This tool loads two PDFs in your browser: a base document and a source
document. You can optionally filter base pages (keep list), pick source
pages to insert, and define the insertion point using a page number.
Enter 0 to insert before the first base page, or a page
number to insert after that page. The output PDF is generated as a new
file, preserving the original documents.
Why Selective Page Merging Matters
Traditional PDF merging often creates oversized, cluttered documents by combining everything. Selective merging gives teams control over exactly what appears in the final file. Legal teams can insert updated exhibits, operations can combine only relevant scanned pages, and project managers can create concise review packets. This reduces back-and-forth edits and lowers the risk of shipping unrelated content in external deliverables.
How to Use
- Upload a base PDF and a source PDF.
- Optionally set base pages to keep (blank = all).
- Set source pages to insert (blank = all source pages).
- Choose insertion point and generate merged output.
Merge Workflow Tips
- Use base keep-pages when you want a shorter destination packet
- Use source page ranges to insert only annexes or specific sections
- Set insertion to 0 to prepend pages at the front
- Double-check page counts shown after upload before final merge
- Keep clear naming conventions for base vs source files
