Merge PDF Files
Your files stay on your device — nothing is uploaded.
How it works
Merge PDF joins several PDF files into one document in the order you set — scanned chapters into a single book, a month of invoices into one file, a contract with all its annexes. Pages are copied as they are, so text stays selectable and images keep their original resolution; nothing is re-compressed. The whole merge runs inside your browser: your files are never uploaded to a server and never leave your device, so even confidential documents are safe to combine here.
- Drop up to 20 PDF files onto the page, or click to browse for them. A fully encrypted PDF has to be unlocked first — use the Unlock PDF tool, then come back.
- Check the numbered list: it is the exact order the pages will follow in the result. The arrows next to each file move it up or down, and the cross removes a file you added by mistake.
- Add more files at any time — the order you already set stays as it is. Twenty files is the limit, and the drop area goes away once you reach it.
- Press “Merge PDFs” and download the combined document.
