Frequently asked questions
Everything you need to know about Merge PDF.
How do I merge PDF files into one?
Upload two or more PDFs, drag them into the order you want, then click Merge PDF. Your combined document is ready to download in seconds.
Will merging reduce the quality of my PDFs?
No. Pages are copied exactly as they are, so all text, images, and formatting stay identical in the merged file.
Is there a limit to how many files I can combine?
You can merge many PDFs in one go. Each individual file can be up to 50 MB.
Is Merge PDF free to use?
Yes. Merge PDF is completely free — no account, no software to install, and no watermark added to your files.
Are my files safe and private?
Your files are uploaded over an encrypted (HTTPS) connection, processed on our servers, and automatically deleted 30 minutes after processing. We never open, share, or keep copies of your documents.
Do I need to install any software?
No. Merge PDF runs entirely in your web browser and works on Windows, Mac, Linux, and mobile devices. There is nothing to download or install.
