The heavy lifting is done by executing pdfunite, a Linux command-line tool available here. You should also be able to deploy this to Cloud Run on GKE if you'd rather run on a different environment. If you'd like to make this available as a service for your friends and family or within your company to avoid sharing files with random online services, then deploying this container image to Cloud Run (see the Getting started section below) is an interesting option.

It should also not be too hard for folks to adapt the code to turn this into a headless service instead of a web app. The application can be improved in many ways such as on UI/UX front (see the Contributing section below).

In contrast with other services available online to merge multiple PDF files into one, this solution can be used as a regular Spring Boot app, a standalone Docker image, or better yet, deployed to Cloud Run. This small web app merges PDF files (think multiple page scans into one file) using a simple Linux command.Ī service based on this code is running here.

If you have HTML markup of the PDF, convert to bytearray using HTMLtoPDF activity. If you have Base64 of the file, convert to bytearray and then pass it to function. Java.io.ByteArrayOutputStream bos = new java.io.ByteArrayOutputStream() PDFMergerUtility merger = new .PDFMergerUtility() PDDocument docf = .PDDocument.load(bis2) PDDocument doc1 = .PDDocument.load(bis1) Java.io.InputStream bis2 = new java.io.ByteArrayInputStream(byteArray2) Java.io.InputStream bis1 = new java.io.ByteArrayInputStream(byteArray1) PDDocument mergedPDF = new .PDDocument() Input : ByteArray of 2 PDFs Output: ByteArray of merged PDF PublicAPI tools = ThreadContainer.get().getPublicAPI() Hi, I wrote a function utilizing the OOTB Apache PDFBox library to merge PDFs in our application.
