Merge PDF files

How to use Merge PDF files

Select PDFs in the order you want them joined. Encrypted or damaged PDFs are rejected; signed documents will lose signature validity when rewritten.

Use up to 20 files totaling 50 MB. PDF editing rewrites the document, so check the output before sharing it. Keep an original copy of signed or important documents.

A practical example

Select PDFs in the required document order. The result appends all pages from the first file, then the next file, and so on. Open the merged PDF to confirm page order and appearance.

Can I merge password-protected or digitally signed PDFs?

Password-protected files are rejected. Rewriting a signed document can invalidate its signature, so keep the original and use an appropriate signing workflow. This tool is for combining ordinary readable PDF pages.
