Merge multiple PDFs
Add two or more PDF files, review the order, and export them as one PDF. You can remove a file before merging if needed.
For this merge flow, the selected PDFs are processed in your browser and are not uploaded to PDFresh.
Browser-side PDF tools and privacy
Review file order
Move files earlier or later. The merged PDF follows this order exactly.
Add at least two PDFs to begin.
Merge order
File orderThis list controls the merged page order. Files higher in the list appear earlier in the result.
Removed files
0Multiple files, one result
Add as many PDFs as you need, then merge them into one output PDF in the browser.
Order before export
Change the file order before downloading so the final merged PDF matches the sequence you need.
Browser-side processing
The core merge flow runs on your device in the browser, so the selected PDFs are not uploaded to PDFresh.

What this tool is for
Use this tool when you need to combine several PDFs such as chapters, invoices, scan batches, or appendices into one file without uploading them. The merged result follows the file order you set on this page.
Limits
Password-protected or damaged PDFs may fail to load. This tool merges full files in the chosen order and does not edit text or rotate pages. If you need to remove pages first, clean each file before merging. Very large batches may take longer depending on your device and browser memory.
Concrete examples
Combine monthly invoices into one package, merge a cover sheet with a proposal, join scanned chapters into one handbook, collect signed forms in one file, merge lecture notes and appendices, or prepare one PDF from separate report sections.
Common mistakes and what to do
If the final order is wrong, move files before downloading and check the list from top to bottom. If one PDF will not load, confirm that it is not password protected or damaged. If you need to delete pages first, clean the files before merging. After export, open the merged PDF and confirm that page order and boundaries are correct.
Privacy and processing
This tool processes PDFs in your browser. The PDFs you select for merging are not uploaded to PDFresh for this workflow. Processing speed and stability still depend on your device and browser.
