About merge pdf files
Merging PDFs joins complete documents into one file without converting their pages to images. It is a quick way to package related contracts, statements, scans or report sections in the sequence a recipient should read them.
Add between two and ten valid PDF files. The merger copies pages from the first document, then the second, and continues in list order. Uploaded filenames are never used as server paths, and temporary files are removed after the download response.
When should I use it?
- Combine a cover letter, form and supporting documents into one submission.
- Join monthly statements or report chapters in chronological order.
- Package several scanner outputs into a single attachment without printing again.

Frequently asked questions
Does merging change page quality?
No. Existing PDF pages are copied into the new document instead of being rendered and recompressed.
Can I merge password-protected PDFs?
No. Encrypted files must be unlocked before upload because the service cannot access their pages.
What determines the order?
The files are processed in the order shown after selection; every page from one file is added before the next file begins.
