How to use the merge pdf
- Select at least two PDF files. Their file selection order determines the order of the merged document.
- Check that the combined file size is no more than 30 MB, then select Process & download.
- Download merged.pdf and review its page order before sharing it.
Worked example
Combine a two-page cover letter and a three-page portfolio to create one five-page PDF. If the order is wrong, select the files again in the desired order.
Frequently asked questions
Are my files uploaded?
No. This tool reads and combines the selected files in your browser. Your documents are not sent to a conversion server.
Can I merge encrypted PDFs?
Password-protected PDFs are not supported. Use an unprotected copy you are entitled to process.
Will digital signatures stay valid?
Creating a new combined document can invalidate existing digital signatures. Keep the signed original files and verify any signing requirements.
