Select two or more PDF files and merge them into one PDF. Order follows your selection or on-page ordering controls.
How to use this tool
- Add PDF files (drag-and-drop or file picker).
- Arrange order if the UI allows.
- Merge and download the combined PDF.
Tips
- Merge only PDFs you have rights to combine.
- For image-only sources, Image to PDF may be simpler than printing to PDF first.
- Huge files can stress memory—merge in batches on older devices if needed.

FAQ
Are PDFs uploaded to a server?
No. pdf-lib merges locally in your browser.
Can I password-protect the result?
This merger focuses on combining files—use a desktop PDF tool for encryption if required.
What if page order is wrong?
Re-order in the UI or re-select files in the sequence you want before merging.
