About PDF Merging
Combining multiple PDF files is useful for consolidating reports, merging scanned documents, or assembling presentations. This tool processes everything in your browser using pdf-lib, so your documents remain completely private.
Frequently Asked Questions
Is there a file size limit?
There's no hard limit, but very large files (100MB+) may be slow since everything processes in your browser's memory.
Are my files uploaded anywhere?
No. All processing happens entirely in your browser. Your files never leave your device.
Can I reorder pages?
You can reorder entire PDF files by dragging them in the list. The pages within each PDF maintain their original order.
Does it work with encrypted PDFs?
Password-protected PDFs cannot be merged. Remove the password first using a PDF tool.
