How to merge PDF files
Choose your PDF documents or drag them into the upload area. Once the files appear, drag their cards to arrange the order you want. Then select Merge PDFs and download the new document.
Your files stay on your device
This tool uses browser-side JavaScript to read and combine your PDFs. The files are processed in the browser rather than being uploaded to a remote processing queue.
Why combine PDF files?
Merging is useful when you need one organized document from several files—for example, a report with supporting pages, a collection of invoices, scanned paperwork, or a complete application package.
Frequently asked questions
Are my PDF files uploaded?
No. The merge operation is performed locally in your browser. Your selected PDF files are read from your device and are not sent to a server by the merge code.
Can I change the PDF order?
Yes. Drag the PDF cards into the order you want before selecting Merge PDFs.
Can I merge several PDFs at once?
Yes. Select multiple PDF files at the same time or add more files in several batches.
What if a PDF is password protected?
A protected PDF may not be readable by the browser library. If merging fails, make sure the document can be opened without a password or use an appropriate PDF-unlocking workflow first.
