How to Use PDF Merger Tool - Complete Guide

Merging PDF files is a common task whether you're combining reports, merging scanned documents, or creating comprehensive documents from multiple sources. Our free PDF merger tool makes this process simple and fast.

What is PDF Merging?

PDF merging combines multiple PDF files into a single document. This is useful when you need to:

  • Combine multiple reports into one document
  • Merge scanned pages into a single PDF
  • Create comprehensive documents from various sources
  • Organize related documents together
  • Prepare documents for sharing or printing

Step-by-Step Guide

Step 1: Upload Your PDF Files

Click the upload button or drag and drop your PDF files. You can upload up to 20 PDF files at once. The tool supports all standard PDF formats.

Step 2: Arrange File Order

Drag files to reorder them. The order you arrange determines how pages appear in the final merged PDF. This is crucial for maintaining document flow.

Step 3: Merge Files

Click the "Merge PDFs" button. The tool processes all files and combines them into a single PDF document. Processing time depends on file sizes.

Step 4: Download Your Merged PDF

Once merging is complete, download your new PDF file. The merged document contains all pages from your uploaded files in the order you specified.

Best Practices

  • Check File Order: Always review the order before merging to ensure pages flow correctly
  • File Size Limits: Individual files should be under 100MB for optimal performance
  • Password Protection: Remove passwords from PDFs before merging for best results
  • Page Count: The tool can handle documents with hundreds of pages
  • Quality Preservation: All original quality and formatting is preserved during merging
