Join PDF Files Online Free
Runs 100% in your browser — your files never leave your device.
When related PDF parts arrive separately, joining them prevents missing attachments and awkward multi-file sharing. Drop the documents into AnkhKit, put them in reading order, and create one continuous PDF using the same private browser merge engine.
How it works
- 1
Select separate PDFs
Add every document that belongs in the joined file.
- 2
Set the reading order
Reorder the inputs before processing.
- 3

Download a single continuous PDF.
About this tool
Joining PDFs into one file
This page opens the PDF merge tool — drop two or more PDFs, arrange their order by dragging, and download one joined document. Everything runs locally in your browser and nothing is uploaded.
Order is the whole craft
The merged document follows the order you arrange — drag the file cards until the sequence matches what the recipient should read. Rename files with numeric prefixes (01-, 02-, 03-) before starting if the order is long and matters.
Frequently asked questions
Is this different from the merge tool?
No — same tool, same result. This page exists for the alternate phrasing; the merge tool is the canonical home.
Does joining re-compress my pages?
No — pages are copied exactly as they are. Quality stays identical and the merged file is roughly the sum of its parts.
Can I remove a file after adding it?
Yes — the file list is editable until you merge. Drag to reorder and remove anything you added by mistake.
