Your PDFs are merged in your browser and are never uploaded or stored.
How to merge PDF files
- Click the box above, or drag and drop your PDF files onto it. You can add several files at once.
- Use the up and down arrows to put the files in the order you want. Remove any file with the cross button.
- Type a name for the merged file if you like, then click Merge PDFs.
- Click the Download button to save your combined PDF.
Is it safe and private?
Yes. The merging happens entirely in your web browser on your own device, so your PDF files are never uploaded to a server or stored anywhere. That makes it suitable for private documents such as contracts and invoices. The page loads a small open-source PDF library when it opens, so it needs an internet connection the first time.
Good to know
- Password-protected PDFs cannot be merged. Remove the password first.
- Pages are combined in the order of the files, and every page of each file is included.
- Bookmarks and some interactive form features may not carry over to the merged file.
- Very large files can be slow or fail on older phones. The total size limit is 100 MB.
