Merge PDF combines several PDF files into one document. Add the PDFs you want to join, drag them into the right order, and download a single merged file — perfect for putting together scanned pages, bundling receipts or statements, or combining chapters and reports into one document.
It works entirely in your browser: your PDFs are read from your device and stitched together locally, so nothing is uploaded to a server. You can add as many files as you like, see how many pages each contains, reorder or remove them, and name the final file before downloading.
How to merge PDF files
- Drag and drop your PDF files, or click “Choose PDFs” to add them.
- Reorder the files with the up/down arrows — they are merged from top to bottom — and remove any you do not need.
- Optionally set a name for the output file.
- Click “Merge PDFs” to combine them and download the single document.
Order is everything
The files are joined in the order shown, top to bottom, and all the pages of each file are kept. So if you want a cover page first, put that PDF at the top; the second file’s pages follow, and so on. Use the arrows to arrange the list before merging.
Private by design
Unlike many online merge tools that upload your documents to a server, this one does everything locally in your browser. That means even confidential PDFs — contracts, bank statements, medical documents — never leave your device, which is the safest way to combine sensitive files.
Password-protected files
A PDF that is encrypted with an open password may not be readable for merging. If a file cannot be added, remove its password first (open it and re-save without protection) and then add it again.
Frequently Asked Questions
How do I combine multiple PDFs into one?
Add all your PDF files, arrange them in the order you want with the up/down arrows, then click “Merge PDFs”. Every page of each file is kept, and you download a single combined document.
Can I choose the order of the files?
Yes. The files are merged from top to bottom in the list, and you can move any file up or down before merging so the pages come out in the right order.
Are my PDFs uploaded to a server?
No. The merge happens entirely in your browser, so your files never leave your device — ideal for confidential documents.
Why won’t one of my files load?
It is usually because the PDF is password-protected or corrupted. Remove the password (open and re-save it without protection) and try adding it again.
Is there a limit on the number or size of PDFs?
There is no fixed limit, but because everything runs in your browser, very large files or many files at once use more memory and take a little longer to process.
