Compress PDF Java REST API

Compress PDF in Java

Using our powerful Java API, developers can compress PDF documents to optimize content and output file size. Reducing PDF size occurs by cleaning up unused data and resources. You can also compress images inside PDF to make the output file size even smaller.

The result of content optimization and compression can be saved in the original PDF or any available save format – DOCX, DOC, RTF, HTML and many others. For example, compress PDF and save the output as Word.

Reduce PDF file size in Java

As mentioned, our Java SDK allows you to programmatically reduce PDF size. And now you can try our powerful functionality and evaluate how to compress PDF in Java with the following example:

Compress PDF using Java

Input file

Upload a file you want to optimize/compress

Run code

Output format

Select the target format from the list

import com.aspose.words.cloud.*;

ApiClient apiClient = new ApiClient("####-####-####-####-####", "##################", null);
WordsApi wordsApi = new WordsApi(apiClient);

byte[] requestDocument = Files.readAllBytes(Paths.get("Input.pdf").toAbsolutePath());
CompressOptions requestCompressOptions = new CompressOptions();
requestCompressOptions.setImagesQuality(75);
requestCompressOptions.setImagesReduceSizeFactor(1);

CompressDocumentOnlineRequest compressDocumentRequest = new CompressDocumentOnlineRequest(
   requestDocument, requestCompressOptions, null, null, null, null);
CompressDocumentOnline compressDocument =
   wordsApi.compressDocumentOnline(compressDocumentRequest);

ConvertDocumentRequest convertDocument = new ConvertDocumentRequest(
   compressDocument.getDocument().iterator().next(), "pdf", null, null, null, null);
