Will the merged PDF lose quality?

No. The merge process preserves the original quality of each PDF. No recompression, no resolution loss, no font substitution—pages appear exactly as they did in the source files.

How many PDF files can I merge at once?

There is no fixed limit on the number of files. You can merge as many PDFs as your browser memory allows. For very large merges (50+ files), the process may take a few moments.

Is my PDF data sent to a server?

No. All processing happens locally in your browser using JavaScript. Your PDF files are never uploaded to any server, ensuring complete privacy for sensitive documents.

Can I reorder the files before merging?

Yes. You can drag and drop files to rearrange them in any order before clicking merge. The page count for each file is displayed so you can verify the sequence.

What happens if one of my PDFs is password-protected?

The merge tool works with standard PDFs. If a PDF is password-protected, you will need to remove the password protection before merging. Most PDF readers allow you to print to PDF as an unlocked version.
