Merge multiple unencrypted PDFs in file-selection order. Files are processed in your browser. Review page order and download the combined PDF.
How to use
- Select PDFs in the desired order
- Check the displayed file list
- Merge the files
- Review the combined PDF and download
Practical example
A two-page file followed by a three-page file creates a five-page PDF. Order follows the browser’s selected file list; drag-to-reorder is not available in this version.
Privacy and file limits
The tool does not upload your files. Processing happens in this browser. Limit: 25 MB per file, 50 MB total and 30 files; decoded images up to 24 megapixels. Keep the original and review every output.
Troubleshooting
Choose a supported format and an unencrypted PDF. If memory runs low, use smaller files or fewer files. A low KB limit may be impossible at large dimensions. Do not use PDF edits for signed or interactive documents without checking the result.
