As an uncompressed bitmap format, BMP can preserve the complete original image data, but the large file size of images has become the most critical issue in image management. The JPG image format offers significant advantages in optimizing storage and improving system performance, while BMP, at the same resolution as JPG, is several times larger in file size, resulting in low network transmission efficiency and occupying considerable storage space. In scenarios such as photography, medical imaging, web content, and mobile app development, JPG's lossy compression can save a large amount of storage space without compromising visual quality. So how can we reduce the file size of these BMP images without significantly degrading image quality? Here is a method that can directly batch convert hundreds or thousands of BMP images to JPG format, while also supporting JPEG, PNG, TIF, WEBP, SVG, and various other image formats.
1. Use Cases
When creating web pages, attachments often include many images in BMP format. However, because BMP lacks a compression mechanism, using these images directly on web pages can significantly reduce loading speed. In such cases, we can batch convert them to JPG format to quickly improve the page's response time.
