Overview
How to Convert BMP to WEBP Images and Photos with Python
Image files conversion from one format to another is a common task encountered by every graphic designer. The efficiency and excellence in converting files not only impact the speed of completion but also play a crucial role in assessing the overall work quality. Concerning the images sources, they frequently necessitate transformation into alternative formats more suited for printing or online distribution. An image crafted in a graphic editor is likely to be in vector format. In such instances, for website publication, it must undergo rasterization and be saved in a raster format. You have the option to convert the image in an uncompressed format for superior quality or save it to a lossless compressed format to minimize the file size. For scenarios where file size reduction is obligatory, like in website applications, there’s the possibility of conversion to lossy compression formats. Specialized data compression algorithms for images can significantly diminish file size while upholding acceptable image quality, ensuring swift image loading. To convert images and photos from BMP to WEBP, we will employ Aspose.Imaging for Python via .NET API which is a feature-rich, powerful and easy to use image manipulation and conversion API for Python platform. You may install it using the following command from your system command.
The system command line
>> pip install aspose-imaging-python-net
Steps to Convert BMP to WEBP via Python
Developers can easily load & convert BMP files to WEBP in just a few lines of code.
- load BMP file with Image.Load method;
- create & set the instance of required subclass of ImageOptionsBase (e.g. BmpOptions, PngOptions, etc.);
- call the Image.Save method;
- pass file path with WEBP extension & object of ImageOptionsBase class.
System Requirements
Before running the conversion example code, make sure that you have the following prerequisites:
- Operating system: Windows or Linux.
- Development environment: Supports .NET Core 7 and higher, such as Microsoft Visual Studio.

BMP What is BMP File Format
Files having extension .BMP represent Bitmap Image files that are used to store bitmap digital images. These images are independent of graphics adapter and are also called device independent bitmap (DIB) file format. This independency serves the purpose of opening the file on multiple platforms such as Microsoft Windows and Mac. The BMP file format can store data as two-dimensional digital images in both monochrome as well as color format with various colour depths.

WebP, introduced by Google, is a modern raster web image file format that is based on lossless and lossy compression. It provides same image quality while considerably reducing the image size. Since most of the web pages use images as effective representation of data, the use of WebP images in web pages results in faster loading of web pages. As per Google, WebP lossless images are 26% smaller in size compared to PNGs, while WebP lossy images are 25-34% smaller than comparable JPEG images. Images are compared based on the Structural Similarity (SSIM) index between WebP and other image file formats. WebP is a sister project of WebM multimedia container format.
