Batch Merge PDFs
Batch Merge PDFs is a Windows desktop app by 3thousand30 for merging all the PDFs in a folder into one combined PDF file — in filename order.
Select a folder. Merge. Done.
How it works
- Select your PDF folder — pick a folder containing the PDF files you want to merge
- Choose an output folder — the merged PDF is saved here, named after your input folder
- Merge — all PDFs are combined in filename order into one output file
Files merge in alphabetical filename order, so you control the sequence by naming your files accordingly — for example 00_cover.pdf, 01_chapter1.pdf, 02_chapter2.pdf, 99_end.pdf.
All merging happens locally on your machine. Your files are not uploaded anywhere.
Key features
