Encrypted files must be unlocked before they can be combined.

A single PDF is easier to submit, archive and share.

Merging normally copies page data, so image quality should not be intentionally reduced.

Open the result and check boundaries between source files.
Large combined documents may be slow on phones; merge fewer files at a time if needed.

FAQ

Can I change the order before merging?

The displayed selection order is used. Clear the list and choose the files again in the required order.

Does merging reduce page quality?

The tool copies pages rather than intentionally rasterizing them, so visual quality should remain the same.

Why is an encrypted PDF rejected?

Password-protected PDFs are not supported. Unlock the file with a trusted PDF application before using this tool.
