Merge PDF on Windows: what it is and when to use it

Windows doesn't include a built-in tool to merge PDFs, so most people end up with heavy programs or sites that upload files to the cloud. With Rayo PDF GO you do it in your browser or with the desktop app, without sending your documents to any server.

Drag the files in from File Explorer, put them in order, and save the final PDF wherever you want.

Common uses

Gather invoices, receipts, or statements into one document.
Build a portfolio or resume packet with attached certificates.
Combine multi-page scans taken separately.
Prepare school assignments or paperwork that asks for a single file.

Tips for better results

Put the files in order before merging: the result follows that order.
If the final file is large, run it through Compress PDF afterward.
Check the result in the viewer before sending it.
