How PDF merging works
PDF merging combines pages from multiple PDF files into one document.
Each input PDF contributes its pages to the merged output.
File order controls the final page order.
Browser-based merging may not preserve every advanced PDF feature.
This version merges all pages from each selected PDF.
Large PDFs can take longer and use more browser memory.
PDF files, pages, order, and document structure explained
PDFs are page-based documents.
Merging usually copies pages into a new PDF.
Reordering files changes the order of the final document.
Different PDFs can have different page sizes and orientations.
The merged output may contain mixed page sizes.
Page ranges are not implemented in this paste-ready version.
File size, page count, security, and compatibility notes
Large PDFs may take longer and use more browser memory.
Password-protected or encrypted PDFs may not merge.
Corrupted PDFs may fail validation.
Digital signatures may be invalidated after merging.
Forms, annotations, bookmarks, layers, and metadata may not be preserved.
Keep original files before merging important documents.
