PDF Merger
Merge multiple PDFs into one file in your browser. No upload to server—files stay on your device.
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.
