Compress

With the PDF Compression tool, you can compress your PDFs. The following examples show how to upload a PDF file and run the PDF Compression feature using Java, PHP, C#, Python, and Swift programming languages. Then, output a compressed PDF file.

Java

// Create a client
CPDFClient client = new CPDFClient(publicKey,secretKey);

// Create a task
// Create an example of a PDF Compression task
CPDFCreateTaskResult result = client.createTask(CPDFDocumentEditorEnum.COMPRESS);

// Get a task id
String taskId = result.getTaskId();

// File handling parameter settings
CPDFCompressParameter fileParameter = new CPDFCompressParameter();
fileParameter.setQuality("50");

// Upload files
client.uploadFile(new File("test.pdf"), taskId, fileParameter);

// Execute task
client.executeTask(taskId);

// Query TaskInfo
CPDFTaskInfoResult taskInfo = client.getTaskInfo(taskId);

PHP

// Create a client
$client = new CPDFClient('public_key', 'secret_key');

// Create a task
// Create an example of a PDF Compression task
$taskInfo = $client->createTask(CPDFDocumentEditor::COMPRESS);

// File handling parameter settings
$file = $client->addFile('test.pdf')
    ->setQuality('50');

//Upload files
$fileInfo = $file->uploadFile($taskInfo['taskId']);

//Execute task
$client->executeTask($taskInfo['taskId']);

//Query TaskInfo
$taskInfo = $client->getTaskInfo($taskInfo['taskId']);

C#

// Create a client
CPDFClient client = new CPDFClient(publicKey,secretKey);

// Create a task
// Create an example of a PDF Compression task
CPDFCreateTaskResult result = client.CreateTask(CPDFDocumentEditorEnum.COMPRESS);

// Get a task id
string taskId = result.TaskId;

// File handling parameter settings
CPDFCompressParameter fileParameter = new CPDFCompressParameter();
fileParameter.Quality = "50";

// Upload files
client.UploadFile(new FileInfo("test.pdf"), taskId, fileParameter);

// Execute task
client.ExecuteTask(taskId);

// Query TaskInfo
CPDFTaskInfoResult taskInfo = client.GetTaskInfo(taskId);

Python

# Create a client
client = CPDFClient(public_key, secret_key)

# Create a task
# Create an example of a PDF Compression task
create_task_result = client.create_task(CPDFDocumentEditorEnum.COMPRESS)

# taskId
task_id = create_task_result.task_id

# File handling parameter settings
file_parameter = CPDFCompressParameter()
file-parameter.quality = "50"

# Upload file
upload_file_result = client.upload_file('test.pdf', task_id, file_parameter)

# Execute task
client.execute_task(task_id)

# get task processing information
task_info = client.get_task_info(task_id)

Swift

// Create a client
let client: CPDFClient = CPDFClient(publicKey: public_key, secretKey: secret_key)

Task { @MainActor in
    // Create a task
    // Create an example of a PDF Compression task
    let taskModel = await client.createTask(url: CPDFDocumentEditor.COMPRESS)
    // Get a task id
    let taskId = taskModel?.taskId ?? ""

    // Upload file
    let path = Bundle.main.path(forResource: "test", ofType: "pdf")
    let uploadFileModel = await client.uploadFile(filepath: path ?? "", password: "", params: [CPDFFileUploadParameterKey.quality.string():"50"], taskId: taskId)
    
    // Execute task
    let _ = await self.client.processFiles(taskId: taskId)
    // Query TaskInfo
    let taskInfoModel = await client.getTaskInfo(taskId: taskId)
}

Needed Parameters:

• quality: Compressed document quality in the range 0-100, e.g. 50.

Result:

File Type	Description
.pdf	The PDF file after compressing.
