Merge PDF
Combine multiple PDF files into a single document, in the order you choose.
About this tool
Upload two or more PDFs and combine them into one file. Pages are added in the order the files are listed, so you control how the final document reads from first page to last.
The merge runs on the server and the combined file is streamed back to you for download. Uploaded files are processed in memory and not retained after the response is sent.
Frequently asked questions
- How many PDFs can I merge at once?
- You can select several files in one go. For very large documents the practical limit is your upload size and available memory rather than a fixed count.
- Will the original formatting be kept?
- Yes. Pages are copied as-is, so fonts, images and layout in each source PDF are preserved in the merged file.
- Are my files stored?
- No. Files are processed in memory to produce the merged PDF and are not saved on the server afterwards.
