자주 묻는 질문

Is this PDF merger free?

Yes. Convertr lets you merge PDF files for free, with no account, no watermark, and no software installation.

How many PDFs can I merge at once?

You can merge up to 50 PDF files in a single session. Each file can be up to 1 GB.

최대 PDF 파일 크기는 얼마인가요?

Each PDF file can be up to 1 GB, the same limit as every other Convertr tool.

업로드된 PDF는 비공개인가요?

Files are processed on Convertr servers and automatically deleted after merging. The tool is built for quick file conversion, not long-term document storage.

Does merging change PDF quality?

No. qpdf concatenates the pages without re-encoding or re-compressing images, so the merged PDF keeps the exact same quality as the originals.

Convertr는 비밀번호로 보호된 PDF를 지원하나요?

Unlock each PDF first if you know the open password and are authorized to modify it. The merger skips encrypted files it cannot read.
