# Merge PDF

ToolSugar joins two or more PDF files into a single PDF inside your browser. Add the files, move them up or down until the list shows the order you want, and press Merge PDFs. The pages of each file are copied unchanged, so text stays selectable and nothing is uploaded.

Runs on your device

## How it works

1. Choose two or more PDFs, or drop them on the box. Adding more later keeps the files already listed.
2. Use the up and down arrows on each row to set the order, and the cross to remove a file.
3. Press Merge PDFs and wait for the page count to appear.
4. Download merged.pdf.

## Key facts

- **Result**: One PDF with every page of every file, in list order
- **Quality**: Pages are copied as they are, so text stays selectable
- **Where it runs**: In your browser. The file is not uploaded and no account is needed.
- **Not supported**: Password protected PDFs must be unlocked first

## Common uses

- Combine a cover letter, CV and certificates into one application file.
- Put scanned receipts from a month into a single expense report.
- Stitch chapters exported separately into one document before sending.

## Questions

### Can I change the order of the PDFs before merging?

Yes. Every file is a row with up and down buttons. The page order of the result follows the list from top to bottom, and each file keeps its own page order.

### Does merging make the file quality worse?

No. The pages are copied into the new document without being redrawn, so text stays sharp and selectable. The size is about the sum of the inputs.

### What happens with a password protected PDF?

The tool stops and names the file that is locked. Remove the password in the program that made it, then add the file again.

### How many PDFs can I merge?

The tool sets no file count limit. The real limit is the memory of your device, since it holds every file while it builds the result.

### Are my PDFs uploaded, and do I need an account?

No to both. The merge runs inside your browser, so your files stay on your device, and there is no sign up.
