Understanding the Concepts

The merger processes each uploaded file sequentially, stitching pages together while maintaining the original page sizes and orientations. You can reorder files by dragging them into place before merging, so the final document reads exactly as intended. Because everything runs in your browser, no files are uploaded to a server.

Frequently Asked Questions

Is there a limit to how many files I can merge?

There is no hard limit. Performance depends on your browser and the total file size, but merging dozens of typical documents works smoothly.

Will the merged PDF keep my bookmarks?

Yes. Bookmarks from each source file are preserved in the final document.

Can I merge password-protected PDFs?

You will need to remove the password first. Use the PDF Password Protector tool to unlock files before merging.
