How to Delete Pages from a PDF Using Syncfusion API

16 Feb 20264 minutes to read

This feature allows you to delete pages in a PDF document. To perform this operation, you need to supply a PDF document as input to the Delete Pages API.

Delete PDF Pages

To delete PDF pages, send a request to the /v1/edit-pdf/delete-pages endpoint with a PDF document and its options as shown below.

Curl

curl --location 'http://localhost:8003/v1/edit-pdf/delete-pages' \
--form 'file=@"Input.pdf"' \
--form 'settings={
   "File": "file",
  "Password": null,
  "PageRanges": [
    {
      "Start": 1,
      "End": 2
    }]
}'

JavaScript

const formdata = new FormData();
formdata.append("file", fileInput.files[0], "Input.pdf");
formdata.append(
  "settings",
  JSON.stringify({    
    File: "file",      
    Password: null,
    PageRanges: [
      { Start: 1, End: 2 }         ]
  })
);

const requestOptions = {
  method: "POST",
  body: formdata,
  redirect: "follow"
};

fetch("http://localhost:8003/v1/edit-pdf/delete-pages", requestOptions)
  .then((response) => response.text())
  .then((result) => console.log(result))
  .catch((error) => console.error(error));

C#

var client = new HttpClient();
var request = new HttpRequestMessage(HttpMethod.Post, "http://localhost:8003/v1/edit-pdf/delete-pages");
var content = new MultipartFormDataContent();
content.Add(new StreamContent(File.OpenRead("Input.pdf")), "file1", "Input.pdf");

var settings = new
{
    File = "file",
    Password = (string?)null,
    PageRanges = new[]
    {
        (Start: 1, End: 2)
    }
};

var json = JsonSerializer.Serialize(settings);
var settingsContent = new StringContent(json, Encoding.UTF8, "application/json");
content.Add(settingsContent, "settings");
request.Content = content;

using var response = await client.SendAsync(request);
response.EnsureSuccessStatusCode();
Console.WriteLine(await response.Content.ReadAsStringAsync());

Once the request is sent, it will create a job to delete PDF pages and return the job details as follows:

{
    "jobID": "6be827c5-d86d-4fe5-9bd5-c8fd5887a455",
    "status": "requested",
    "createdAt": "2024-05-06T09:39:13.9505828Z"
}

Poll the status of the Delete Pages Job

Next, you can retrieve the job status by sending a request to the /v1/edit-pdf/status/{jobID} endpoint with the job ID.

Curl

curl --location 'http://localhost:8003/v1/conversion/status/9b131bfe-d4eb-4f1d-b946-46443a363eb5' \
  --output Output.pdf

JavaScript

const requestOptions = {
  method: "GET",
  redirect: "follow"
};

fetch("http://localhost:8003/v1/edit-pdf/status/4413bbb5-6b26-4c07-9af2-c26cd2c42fe3", requestOptions)
  .then((response) => response.text())
  .then((result) => console.log(result))
  .catch((error) => console.error(error));

C#

var client = new HttpClient();
var request = new HttpRequestMessage(HttpMethod.Get, "http://localhost:8003/v1/conversion/status/ef0766ab-bc74-456c-8143-782e730a89df");
var response = await client.SendAsync(request);
response.EnsureSuccessStatusCode();
Console.WriteLine(await response.Content.ReadAsStringAsync());

You will receive one of the following statuses until the job is completed. Upon completion, you will receive the actual output file.

Job Statuses:

• Queued:

{
    "jobID": "4b2782b2-9f08-478b-98fc-4464bd219ca0",
    "status": "queued"
}

• In Progress:

{
    "jobID": "ef0766ab-bc74-456c-8143-782e730a89df",
    "status": "in progress"
}

• Error:

{
    "jobID": "ef0766ab-bc74-456c-8143-782e730a89df",
    "status": "errror",
    "code": "500",
    "message": "Failed to convert the document to PDF"        
}
