Tips for best results
- Name your files logically (01-intro.pdf, 02-body.pdf) to make ordering easier.
- Each PDF's page orientation is preserved — landscape and portrait pages can coexist.
- Bookmarks and table of contents from individual PDFs may not be merged automatically.
- The output file size equals roughly the sum of all input files.
