Combine PDFs into a single file

How merging works and how to control page order

Add two or more PDFs, drag the arrows to arrange them, and DocMak appends every page of each file into one new document in exactly the list order shown. Pages are copied rather than re-rendered, so fonts, vector graphics, embedded images and page sizes survive the merge — mixed A4 and Letter pages simply keep their own dimensions inside the combined file.

The merge runs entirely in your browser using pdf-lib, so confidential material such as licence copies, shareholder documents or payroll files never leaves your device. There is no watermark on the output and no signup step before downloading.

Typical uses

• Combine trade licence, passport copies and MOA into a single bank or tender attachment
• Join a quotation, terms sheet and company profile into one client-ready PDF
• Assemble monthly invoices or receipts into one file for your accountant
• Reorder scanned pages that came out of the scanner in the wrong sequence
