Merge PDF Files
Combine multiple PDF files into one, in whatever order you choose. Everything runs in your browser — your files are never uploaded anywhere.
Drop PDF files here, or click to browse
Add two or more PDF files. They stay on your device — nothing is uploaded.
How to merge PDF files
- Drop or select two or more PDF files.
- Reorder them using the up/down controls — files merge in the order shown.
- Click "Merge PDFs" and download the combined file.
Your files stay on your device
This tool processes PDFs entirely in your browser using client-side JavaScript. Your files are never uploaded to a server, which means they can't be stored, inspected or lost in transit — and it works the same whether you have one file or a hundred.
- No upload
- Files are read and merged locally in your browser — nothing is sent to a server.
- Merge order
- Files combine in the order they're listed, top to bottom.
Questions
Are my PDF files uploaded anywhere?
No. The merge happens entirely in your browser using JavaScript — your files are read locally and the combined PDF is generated on your device. Nothing is sent to a server at any point.
Can I change the order the files are merged in?
Yes. Files merge in the order they're listed — use the up and down controls next to each file to reorder them before merging.
Is there a file size or count limit?
There's no artificial limit set by this tool, but since everything runs in your browser's memory, very large files or a very large number of files may be limited by your device's available memory rather than by the tool itself.
What happens if one of my files is corrupted or password-protected?
That file is skipped and named after merging so you know exactly which one failed — the rest of your files still merge normally.
