Converting PowerPoint to PDF Using Syncfusion Web API

24 Mar 20265 minutes to read

The syncfusion PowerPoint to PDF Web API enables you to convert presentation files into polished, high‑quality PDF documents while preserving slide layouts, fonts, images, charts, and visual effects. Each slide is accurately rendered as a PDF page, ensuring consistent appearance across devices and platforms. The conversion supports customization options such as accessibility tagging for screen readers and PDF/A compliance for long‑term archiving.

Convert PowerPoint to PDF

To convert a PowerPoint document to PDF, send a request to the /v1/conversion/powerpoint-to-pdf endpoint, including both the PowerPoint file as input and the settings JSON.

Curl

curl --location 'http://localhost:8003/v1/conversion/powerpoint-to-pdf' \
--form 'file=@Input1.pptx' \
--form 'settings={
  "File":"file",
  "Password": null,
  "PdfComplaince": "PDF/A-1B",
  "EnableAccessibility": false
}'

JavaScript

const formdata = new FormData();
formdata.append("file", fileInput.files[0], "Input1.pptx");
formdata.append(
    "settings",
    JSON.stringify({
      File: "file",
      Password: null,
      PdfCompliance: "PDF/A-1B", 
      EnableAccessibility: false
    })
  );

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

fetch("http://localhost:8003/v1/conversion/powerpoint-to-pdf", 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/conversion/powerpoint-to-pdf");
var content = new MultipartFormDataContent();
content.Add(new StreamContent(File.OpenRead("Input1.pptx")), "file", "Input1.pptx");
var settings = new
{
    File = "file",
    Password = (string?)null,
    PdfCompliance = "PDF/A-1B",
    EnableAccessibility = false
};

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

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

PowerPoint to PDF settings

Password

Specifies the password required to open a protected Word document before converting it to PDF.

PdfCompliance

Defines the PDF/A compliance level for archival and standards adherence. Supported levels include PDF/A‑1B, PDF/A‑2B, PDF/A‑3B, and PDF/A‑4.

EnableAccessibility

Applies accessibility tags to the PDF to improve compatibility with screen readers and assistive technologies.

Presentation to PDF Job Response

Once the request is sent, it will create a conversion job to convert the PowerPoint to PDF and return the job details as follows:

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

Check Presentation to PDF Job Status

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

Curl

curl --location 'http://localhost:8003/v1/conversion/status/f58c9739-622e-41d4-9dd2-57a901dc13c3' \
  --output Output.pdf

JavaScript

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

fetch("http://localhost:8003/v1/conversion/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"
