Merge PDFs online for free, no software needed
The PDF merge tool lets you combine multiple documents — contracts, invoices, assignments, records — into a single file in seconds. Unlike many other sites, the entire process runs with JavaScript right in your browser: your file never leaves your computer.
Reorder files before merging
After selecting your files, you can drag-and-drop to change the order of the documents before merging. This is handy when you need a cover page first or an appendix at the end.

Frequently Asked Questions — Merge PDF
No. Everything is processed right in your browser with JavaScript, so your file is never sent anywhere and stays fully private — even sensitive documents like contracts or ID papers.

It's completely free, no sign-up required, no usage limits, and no ad watermark added to your file.
