In this concise guide you’ll discover how to Python ImagingAPI‑based conversion of a JPG image to PNG using the Aspose.Imaging Cloud REST API, enabling you to embed the functionality into any Python application running on Windows, macOS, or Linux.

Prerequisite

• Create an account and get API credentials to perform JPG to PNG conversion
• Download the Aspose.Imaging Cloud SDK for Python from the official repository
• Set up a Python project and add the SDK as a dependency

Steps to Convert JPG to PNG with Python REST API

1. Set the client_id and client_secret for the API to convert JPG to PNG.
2. Create an instance of the ImagingApi class with the client credentials.
3. Define the source JPG file name and the desired PNG output file name.
4. Load the sample JPG file from local storage and upload it to Aspose Cloud storage.
5. Instantiate a ConvertImageRequest with the input JPG file stream and specify the PNG format.
6. Call the convert_image method to perform the conversion.
7. Save the returned PNG file stream to the local disk.

The conversion workflow is straightforward: initialize the SDK via ImagingApi, read the source JPG into a file stream, create a ConvertImageRequest, and invoke convert_image to obtain the PNG result.
