PDF ToolsCombine multiple PDFs into one, in any order

About the PDF Merge
Combine two or more PDF files into a single document. Add files, reorder them with the up/down arrows, and merge — the whole operation happens locally in your browser, so nothing you upload here ever leaves your tab.
A common need for assembling a single document from several sources — combining scanned pages, stitching together chapters or reports, or bundling multiple invoices into one file for submission — without installing desktop software or trusting an unknown website with the contents.
How to Use the PDF Merge
Click Add PDFs and select two or more files.
Reorder them with the up/down arrows — the merge follows this exact order.
Click Merge PDFs, then download the combined file.
Frequently Asked Questions
Are my PDF files uploaded anywhere?
No. Every file you add is read and merged directly in your browser using JavaScript — nothing is sent to a server, so it works fine offline and is safe to use on confidential documents.
Can I control the order the PDFs are merged in?
Yes — after adding files, use the up/down arrows next to each one to reorder them before merging. The final document follows that exact order.
What happens with a password-protected PDF?
Encrypted PDFs can't be processed — you'll get a clear error telling you to remove the password first (in whatever tool originally protected it) before merging.
Is there a limit on how many files I can merge, or their size?
No hard limit is enforced, but very large or numerous files take longer since everything is processed on your own device rather than a server. For typical documents — reports, scans, invoices — merging is effectively instant.
