How to Merge PDF Files

The process takes three steps and does not require installing desktop software or uploading sensitive files to an online converter.

1. Upload your PDFs

Select two or more PDF files from your device. Each file can be up to 50MB for reliable browser performance.

2. Arrange the order

Use the up and down buttons to arrange your PDFs in the order you want them to appear in the merged document.

3. Download the merged file

Click merge and your combined PDF downloads instantly. All pages from your selected files are combined into one document.

Important Limitations

PDFs that are password-protected cannot be merged. If a file requires a password, use our PDF Unlock tool first to remove the protection, then merge the unlocked copy.

All files are processed locally in your browser. Large files (over 50MB) or very large page counts may cause slower performance depending on your device's available memory.
