合并 PDF

Add the PDF files you want to combine, then drag them into the order you prefer. Once arranged, the tool joins them into a single document while keeping each file's original fonts, layout, and formatting. Download the merged result right away.

Yes. Before combining, you can drag each file into your preferred sequence so the final document follows the exact order you want. This is handy when consolidating chapters, invoices, or contracts that need to appear in a specific arrangement.

You can merge as many PDF files as you need into one document. Because everything runs locally in your browser using your own device's memory, very large batches depend on your computer's available resources rather than a fixed server cap.

No. All merging happens directly in your browser, so your PDFs never leave your device or touch a server. This keeps sensitive documents like contracts and financial reports completely private and confidential throughout the process.

Completely free, with no signup or account required. You can combine unlimited PDFs as often as you like at no cost, and there are no watermarks added to your merged document.
