In our previous blog post, we learned how to convert RAR files to JPG in .NET. This article demonstrates how to achieve RAR to PNG conversion in a Node.js-based application. GroupDocs.Conversion offers Cloud SDKs and REST APIs to perform file conversion and manipulation among many popular file formats. In addition, there is an online RAR to PNG converter that is also backed by GroupDocs.Conversion Cloud SDK. Basically, you have both options either convert RAR to PNG programmatically or manually by using a web-based online tool. So, let’s start this guide and see how to convert RAR files to PNG in Node.js programmatically.
The following points shall be covered in this article:
- File Conversion API Installation - GroupDocs.Conversion
- Convert RAR Files to PNG in Node.js Programmatically
- Online RAR to PNG Converter
File Conversion API Installation - GroupDocs.Conversion
The installation of any cloud-based library matters when it comes to rapid application development. However, the installation process of GroupDocs.Conversion Cloud SDKs for Node.js is quite simple. Simply, run the following command into the terminal/CMD and it will be installed in a few seconds:
npm install groupdocs-conversion-cloud
After the installation, the next step is to obtain the API credentials (i.e. Client Secret, Client API). Again, you can get these credentials from our API Cloud dashboard by performing a few clicks.
Note: You may visit our tutorial on obtaining the API credentials.
Convert RAR Files to PNG in Node.js Programmatically
Let’s get to the point now. We will write a code sample in Node.js to build an RAR file converter for our business application. For that purpose, we already have a source RAR file in the API Cloud dashboard. Although, you can also upload by calling the UploadFile method. Nevertheless, you can upload manually too.
So, the following steps demonstrate how to convert RAR to PNG using this file conversion API:
- First, require the groupdocs-conversion-cloud module into your Node.js project.
- Call the fromKeys method of the ConvertApi class and pass the API credentials(Client ID + Client Secret).
- Instantiate an instance of the ConvertSettings class.
- Assign the values to the properties of the ConvertSettings class such as storageName, filePath, format, and outputPath.
- Initialize an object of the ConvertDocumentRequest class with the instance of the ConvertSettings class.
- Invoke the convertDocument method to convert RAR to PNG.
The following code snippet is for RAR to PNG conversion in Node.js:
After a successful run, you will see a PNG(i.e. output-sample.png) file generated in the “test” folder. This file conversion API provides the DownloadFile method to download the files programmatically.
Online RAR to PNG converter
