How to Merge PDF Files Online for Free
Combine several PDFs into one file in the order you want, without installing software or uploading your documents.
Merging PDFs is one of the most common document jobs: a CV and its certificates, a set of invoices for one month, or scanned pages that came out as separate files. This guide shows the quickest way to do it in your browser.
Before you start
Put the files you need in one folder and give them clear names. The order you choose matters, because the merged PDF follows it from the first file to the last.
Steps
- Open the Merge PDF tool and select all the PDFs you want to combine. You can pick several files at once or add more later.
- Use the arrows on each file to move it up or down until the order is right.
- Click Merge PDF. The combined file downloads as merged.pdf.
- Open the result and scroll through it to check the page order.
Tips for a clean result
- Merge small files first to check the order, then add the rest.
- If one file is much larger than the others, compress it first so the final file stays easy to email.
- Password-protected PDFs must be unlocked before they can be merged.
- Keep your original files until you have checked the merged copy.
Your files are processed on your own device. They are not uploaded to a server, which makes this approach suitable for documents such as contracts and ID copies.
Common problems
If the merge fails, one of the files is usually damaged or protected. Try opening each file in your browser first. If a file asks for a password, unlock it and try again.
