Merge PDF

What to know before using this tool

PDF merging copies pages from multiple source documents into one output file. It does not edit text, optimize scanned images or automatically remove duplicate pages. If you need to extract or reorder pages, use the dedicated PDF page tools before or after merging.

Very large PDFs can require significant browser memory, particularly on older phones. When working with important documents, download the result and open it to make sure every expected page is present and readable.

How to use it

1. Choose two or more PDF files.
2. Select them in the sequence you want for the final document.
3. Click the merge action.
4. Wait while the browser copies the pages into a new PDF.
5. Download the merged PDF and verify the page order.

Common uses

• Combining a cover letter and supporting documents.
• Joining monthly statements or reports.
• Putting several scanned sections into one upload.
• Creating one printable file from multiple PDF sources.

Tips for better results

• Arrange source files before selecting them to make page order predictable.
• Use Extract PDF Pages first if a source file contains pages you do not need.
• Use Reorder PDF Pages when individual pages need a custom sequence.
• Keep source PDFs until you have checked the merged result.
