Check a one-page cover plus a two-page body

About this tool
Merge PDFs or extract the pages you need directly in your browser. PDF files are not uploaded to a server; processing happens in the browser on your device.
Password-protected PDFs are not supported. Very large PDFs or PDFs with many pages may take longer to process or may not work on every device.
PDF processing uses pdf-lib under the MIT License.
