PDF Java developers can effortlessly append PDF files using the Aspose PDF Cloud REST API. This short tutorial shows how to combine an entire PDF or a specific page range with another PDF directly from your Java application, leveraging the official Aspose PDF Cloud SDK for Java. For more details on the PDF format, visit the PDF file information page.
Prerequisite
- Create an account API credentials
- Download the Aspose.PDF Cloud SDK for Java
- Set up a Java project with the SDK to enable PDF appending operations
Steps to Append PDF Documents with Java Low Code API
- Configure the client ID and secret in the PdfApi instance for authentication.
- Load the target PDF file and the source PDF file that you want to append.
- Call the PostAppendDocument() method to attach the source PDF to the target PDF.
- Specify the start and end page numbers of the source PDF (use 0 for both to append the whole document).
- Download the resulting PDF, which now contains the appended content, and save it locally.
These steps illustrate how to append PDF files with Java REST Interface. Load the two PDFs, define the page range (if needed), invoke PostAppendDocument(), and store the combined file on disk.
Code to Append PDF to PDF with Java REST API
The sample demonstrates how to append PDFs together with the Java‑based API. The PostAppendDocument() method receives the target PDF as the first argument and the source PDF (to be appended) as the second. Omitting the start/end page values or setting both to 0 results in the complete source PDF being appended.
If you need to split a PDF instead, see the related guide: Split PDF Document with Java REST API.
