Convert HTML to PDF - Cloud SDKs

Summary

Aspose.HTML Cloud v4.0 provides the simplest API to convert HTML documents to PDF format with high quality, easy and fast. HTML files are frequently used to create, edit, or communicate a lot of information. HTML to PDF conversion is often required to establish limited access to documents editing or copying, to produce official documentation, or send some information, for example, by email.

The article explains in a set of Aspose.HTML Cloud SDKs and REST API examples how to convert HTML to PDF. We will consider various scenarios of HTML to PDF conversion: from storage to storage, local file to the local file system and from the Web to a local file system.

Examples of HTML to PDF Conversion

A widespread use case for Aspose.HTML Cloud functions is file processing and converting. Aspose.HTML Cloud allows you to fetch an HTML document from a storage location by its name, from a URL or a local file on your drive, convert it to a specified format and save it to the storage or a local drive. The following code examples demonstrate how to convert HTML to PDF for different cases using available SDKs and REST API. A family of SDKs is available to help developers speed up their development, including C#, Java, C++, Python, PHP, Ruby, Swift, Java/Android, Node.js, etc.

Example 1. Convert a local HTML file to PDF and save the result to local path

The following example demonstrates the simplest way to convert HTML to PDF C# language applying. Local HTML converted to PDF and saved to the local path. You can download the C# SDK from the GitHub repository .

// Initialize SDK API
var api = new HtmlApi("CLIENT_ID", "CLIENT_SECRET").ConvertApi;

// Convert HTML to PDF
var result = await api.ConvertAsync("test.html", "test.pdf");

Java

The following example demonstrates how to convert HTML to PDF java language applying. Local HTML converted to PDF and saved to the local path. You can download the java SDK from the GitHub repository .

Configuration.setBasePath("https://api.aspose.cloud");
Configuration.setAuthPath("https://api.aspose.cloud/connect/token");

HtmlApi api = new HtmlApi("CLIENT_ID", "CLIENT_SECRET");

JobBuilder builder = new ConverterBuilder()
                .fromLocalFile("input.html")
                .saveToLocal("output.pdf");

OperationResult result = api.convert(builder);

C++

The following example demonstrates how to convert HTML to PDF C++ language applying. Local HTML converted to PDF and saved to the local path.

// Get current directory
std::string cur_dir(argv[0]);
int pos = cur_dir.find_last_of("/\\");
cur_dir = cur_dir.substr(0, pos + 1); // Include the last slash
std::wstring w_cur_dir(cur_dir.begin(), cur_dir.end());

const utility::string_t clientId = L"XXXXXXXX-XXXX-XXXX-XXXX-XXXXXXXXXXXX";
const utility::string_t clientSecret = L"XXXXXXXXXXXXXXXXXXXXXXXXXXXXXXXX";
const utility::string_t basePath = L"https://api.aspose.cloud/v4.0";
const utility::string_t authPath = L"https://api.aspose.cloud/connect/token";

// Create configuration for authorization
std::shared_ptr<ApiConfiguration> apiConfig(new ApiConfiguration(clientId, clientSecret, basePath, authPath));

// Create client from configuration
std::shared_ptr<ApiClient> apiClient(new ApiClient(apiConfig));

// Create ConversionApi
std::shared_ptr<ConversionApi> api = std::make_shared<ConversionApi>(apiClient);

// File name for conversion
utility::string_t src = w_cur_dir + L"test.html";
utility::string_t dst = w_cur_dir + L"result.pdf";

//Conversion
auto result = api->convertLocalToLocal(src, dst);

// Check the result file
auto re = result->getFile();
std::ifstream f(re.c_str());
if(!f.good())
{
    throw std::runtime_error("Conversion failed");
}

CURL

The following example demonstrates how to convert HTML to PDF using REST API. HTML is taken from the Web, converted to PDF and saved to the local file system. Follow a few required steps:

Call REST API to execute conversion (in the example below).
Download conversion result back from storage using Storage API .

curl -X POST -v \
	"https://api.aspose.cloud/v4.0/html/conversion/html-pdf" \
    -d "{'InputPath': 'https://example.com', 'OutputFile': 'test.pdf'}" \
    -H "Content-Type: application/json" \
    -H "Authorization:Bearer <JWT_token>"

HTML to PDF conversion occurs with the default conversion options: the resulting PDF document’s width and height correspond to A4, all margins have zero value.

Test HTML to PDF conversion online

Insert URL to the text field.
Press “Convert” button.
