Why Merge PDFs?
Combining PDFs is one of the most common document tasks. Maybe you scanned pages separately and need one file. Maybe you have multiple reports, invoices, or forms that belong together. Whatever the reason, merging them into one PDF makes sharing, printing, and organizing much easier.
This tool does it entirely in your browser. Your files never leave your device, so you can merge sensitive documents without worrying about privacy.

Frequently Asked Questions
Are my files uploaded to a server?
No. This tool runs entirely in your browser using PDF-lib. Your files are read locally and the merged PDF is generated on your device. Nothing is sent anywhere.
How many PDFs can I merge at once?
There is no hard limit. You can merge as many PDFs as you want, though very large files may take longer to process depending on your device.
Can I reorder the files before merging?
Yes. Each file has up and down arrows so you can arrange them in the exact order you want before clicking Merge PDFs.
Does the merged PDF keep the original quality?
Yes. The merged PDF preserves all pages, text, images, and formatting from the original files.
Is this tool free?
Completely free. No account, no sign-up, no watermarks, and no limits on how many times you can use it.
