What is a PDF merger?
A PDF merger combines two or more PDF files into a single document. Whether it is a contract with its signature 페이지, a scanned report with an appendix, or several invoices you want to send as one attachment, merging keeps everything in one tidy file that is easy to store, share, and archive.
This tool runs entirely in your browser. Your documents are never uploaded to a server, so merging is instant, private, and free with no file-size limits. Drop in as many PDFs as you need and drag them into the exact order you want in the final file.

Frequently asked questions
Is merging PDFs free?
Yes — completely free with no limits, no watermark, and no signup.
Are my PDFs uploaded to a server?
No. The merge happens locally in your browser with pdf-lib; your files never leave your device.
Can I reorder the files before merging?
Yes. Each added file appears in the list and you can drag it to change its position in the merged document.
Does merging reduce quality?
No. The 페이지 are joined as-is, losslessly, so text and 이미지 keep their original quality.
