Complete guide to merging multiple PDFs and splitting one PDF into many.
The PDF Merge and Split tools let you combine or divide PDF documents without any software installation.
## Merging PDFs
1. Upload multiple PDF files (drag and drop to reorder)
2. Arrange pages in the desired order
3. Click "Merge PDFs"
4. Download the combined document
You can upload up to 20 files and drag them into any order before merging.
## Splitting PDFs
### Split by Page Range
Specify exactly which pages go into each output file. Example: "1-5, 6-10, 11-end"
### Split Every N Pages
Create equal chunks. Split a 100-page PDF into 10-page documents.
### Extract a Single Page
Pull out one specific page as its own file.
### Split Every Page
Create one PDF per page — useful for archiving.
## Tips
- Large PDFs (100+ MB) may take a few seconds to process
- All processing is client-side — your documents never leave your browser
- Merge PDFs before printing for a single clean document
