Convert DWG to DWF using Java REST API

This quick guide shows you how to convert DWG to DWF using Java REST API. By taking advantage of the DWG to DWF conversion with Java Low Code API, you can transform an editable CAD drawing into a lightweight, read‑only DWF file—perfect for secure sharing, viewing, printing, and markup. The entire workflow is executed with the Dotjava‑based Aspose.Cad Cloud SDK.

Prerequisite

Steps to Convert DWG File to DXF using Java-based API

  1. Create a CadApi instance with your App Key, App SID, and baseUrl
  2. Point inputPath to the source DWG and outputPath to the target DWF file
  3. Open the DWG, copy it into a MemoryStream, and reset Position to 0
  4. Build a PutDrawingDwfRequest with the prepared MemoryStream
  5. Call cadApi.PutDrawingDwf(request) to obtain the converted DWF as a stream
  6. Create the destination file and copy the result stream to the outputPath

These steps have summarized the process to change DWG in DWF using Java-based API. First, set up CadApi with your credentials and point it to your DWG file and the DWF you want to create. Then load the DWG into memory, send it with PutDrawingDwfRequest to convert, and save the returned stream as your DWF.

Code for AutoCAD to DWF Converter using Java REST Interface

This example shows how to create an online DWG‑to‑DWF converter using the Java REST API. Although the demo reads the source file from the local disk, you can equally upload multiple files to Cloud storage and run conversions on any of those stored assets. Additionally, the PutDrawingDwfRequest() call accepts optional parameters—such as target page size/DPI, background color, rotation, zoom/scale, and more—enabling you to fine‑tune the resulting DWF to your exact requirements.

Now that you’ve mastered converting DWG files to DWF with the Java REST API, you’re ready to tackle the next format. For a detailed, step‑by‑step walkthrough on turning a DWG into a DXF, check out our guide on Convert DWG into DXF using Java REST API.
