Why Merge PDF Files?
Combining multiple PDFs into one document is one of the most common file tasks. Whether you are assembling a report from multiple chapters, combining scanned documents, creating a portfolio, or organizing receipts for tax season, a PDF merger saves you hours of manual copying and pasting.

Tips for Merging PDFs
- Name your files in order â If you have many PDFs, prefix filenames with numbers (e.g., 01-chapter1.pdf, 02-chapter2.pdf) to make ordering easier.
- Check page count â The merged document will have the sum of all pages from every source PDF.
- Compress after merging â If the merged PDF is too large, use our PDF compressor to shrink it.
- Convert before merging â Need to include images or Word documents? Convert them to PDF first using JPG to PDF or Word to PDF.
