In this post, you’ll learn how to convert PDF to Word in your Java application using ComPDFKit’s PDF to Word API. With our API, you can convert up to 1000 PDF files per month for free. All you need to do is create a free account to get access to your API key. ComPDFKit API Document conversion is just one of our 30+ PDF API tools. You can combine our conversion tool with other tools to create complex document processing workflows. You’ll be able to convert various file formats from or to PDFs, and also to: - Merge, split, insert, extract, and delete specific PDF pages - OCR, watermark, or compress PDFs - Compare documents (including content comparison and overlay comparison) Request Workflow The processing workflow of the ComPDFKit API is very simple. It consists of four basic request instructions: create a task, upload a file, execute a task, and download a result file. Through these four requests, you can select the corresponding PDF tool to process your file and obtain the download link of the result file. How to Convert PDF to Word ComPDFKit supports converting PDF to Word accurately with simple API requests, keeping text, page layout, columns, formatting, graphics, etc. It also supports recognizing and extracting the highlight, underline, squiggly, and strikeout in PDF files, and keeping these annotation features after converting them to Word. What’s more, even if your PDFs include hyperlinks, it is also able to keep the links working properly after conversion. The steps to access the PDF to Word API tool and process PDF conversion are as follows: Step 1 — Creating a Free Account on ComPDFKit Go to our website, where you’ll see the page below, prompting you to create your free account. Once you’ve created your account, you’ll be welcomed by the page below, which shows an overview of your plan details. As you can see on the dashboard, you can process 1000 documents per month, and you’ll be able to access all our PDF API tools. Step 2 — Obtaining the API Key for Authentication After you’ve verified your email, you can get your API key from the dashboard. In the menu on the left, click API Keys. You’ll see the following page, which is an overview of your keys: Now You need to replace public_key and secret_key with accessToken in the publicKey and secretKey authentication return values you get from the console. import java.io.*;
import okhttp3.*;
public class main {
  public static void main(String []args) throws IOException{
    OkHttpClient client = new OkHttpClient().newBuilder()
      .build();
    MediaType mediaType = MediaType.parse("text/plain");
    RequestBody body = RequestBody.create(mediaType, "{\n    \"publicKey\": \"{{public_key}}\",\n    \"secretKey\": \"{{secret_key}}\"\n}");
    Request request = new Request.Builder()
      .url("https://api-server.compdf.com/server/v1/oauth/token")
      .method("POST", body)
      .build();
    Response response = client.newCall(request).execute();
  }
} Step 3 — Creating Task You need to replace the accessToken which was obtained from the previous step, and replace the language type you want to display the error information. After replacing them, you will get the taskId in the response data. import java.io.*;
import okhttp3.*;
public class main {
  public static void main(String []args) throws IOException{
    OkHttpClient client = new OkHttpClient().newBuilder()
      .build();
    MediaType mediaType = MediaType.parse("text/plain");
    RequestBody body = RequestBody.create(mediaType, "");
    Request request = new Request.Builder()
      .url("https://api-server.compdf.com/server/v1/task/pdf/docx?language={{language}}")
      .method("GET", body)
      .addHeader("Authorization", "Bearer {{accessToken}}")
      .build();
    Response response = client.newCall(request).execute();
  }
} Step 4 — Uploading Files Replace the file you want to convert, the taskId obtained in the previous step, the language type you want to display the error information, and the accessToken obtained in the first step. import java.io.*;
import okhttp3.*;
public class main {
  public static void main(String []args) throws IOException{
    OkHttpClient client = new OkHttpClient().newBuilder()
      .build();
    MediaType mediaType = MediaType.parse("text/plain");
    RequestBody body = new MultipartBody.Builder().setType(MultipartBody.FORM)
      .addFormDataPart("file","{{file}}",
 RequestBody.create(MediaType.parse("application/octet-stream"),
                                          new File("")))
      .addFormDataPart("taskId","{{taskId}}")
      .addFormDataPart("language","{{language}}")
      .addFormDataPart("password","")
      .addFormDataPart("parameter","{  \"isFlowLayout\": \"1\",  \"isContainImg\": \"1\"}")
      .build();
    Request request = new Request.Builder()
      .url("https://api-server.compdf.com/server/v1/file/upload")
      .method("POST", body)
      .addHeader("Authorization", "Bearer {{accessToken}}")
      .build();
    Response response = client.newCall(request).execute();
  }
} Step 5 — Processing Files Replace the taskId you obtained from the Create task, and the accessToken obtained in the first step, and replace the language type you want to display the error information. import java.io.*;
import okhttp3.*;
public class main {
 public static void main(String []args) throws IOException{
   OkHttpClient client = new OkHttpClient().newBuilder()
     .build();
   MediaType mediaType = MediaType.parse("text/plain");
   RequestBody body = RequestBody.create(mediaType, "");
   Request request = new Request.Builder()
     .url("https://api-server.compdf.com/server/v1/execute/start?taskId={{taskId}}&language={{language}}")
     .method("GET", body)
     .addHeader("Authorization", "Bearer {{accessToken}}")
     .build();
   Response response = client.newCall(request).execute();
 }
} Step 6 — Getting Task Information Replace taskId with the taskId you obtained from the step "Create the task", access_token replaced by access_token obtained in the first step. import java.io.*;
import okhttp3.*;
public class main {
  public static void main(String []args) throws IOException{
    OkHttpClient client = new OkHttpClient().newBuilder()
      .build();
    MediaType mediaType = MediaType.parse("text/plain");
    RequestBody body = RequestBody.create(mediaType, "");
    Request request = new Request.Builder()
      .url("https://api-server.compdf.com/server/v1/task/taskInfo?taskId={{taskId}}")
      .method("GET", body)
      .addHeader("Authorization", "Bearer {{accessToken}}")
      .build();
    Response response = client.newCall(request).execute();
  }
