Yes — files are merged in the order they appear in your list, which is the order you added them. If you need a specific order, add the files in that sequence.

How to Combine PDF Files Online
Combining PDFs is useful when you have scanned documents saved as separate files, reports split across multiple PDFs, or contracts with attachments that need to be sent as one document. Our merger handles all of these in a single step.
Why Merge PDF Files?
Sending one PDF is simpler than sending five. Merged PDFs are easier to share via email, upload to portals, print, and archive. Combining related documents into one file also makes them easier for recipients to read in the correct order.
Private & Secure PDF Merging
Unlike many online PDF tools that upload your files to cloud servers, this tool merges your PDFs entirely inside your browser. Your documents — including any sensitive contracts, forms, or personal records — are never transmitted or stored on any external server.
