Quality
For web use, it is generally appropriate to set the quality to around 70-90%. This allows you to maintain a small file size while minimizing visual loss. Adjust the quality while checking the preview image and estimated conversion file size.

Edit Image
BMP (Bitmap) is a bitmap image file format used to store pixel data. Each pixel's color is directly specified, preserving high resolution and detail in graphics. BMP is primarily used in Windows environments and is supported by various graphic applications. However, BMP files typically have larger file sizes than other image file formats and do not support compression, resulting in more storage usage. Additionally, they do not support transparency and may not be suitable for web or online use.
JPG, short for Joint Photographic Experts Group, is a standard format for compressing and storing digital images. Widely used for photographs and web images, it maintains a certain level of image quality while reducing file size. It primarily uses Discrete Cosine Transform (DCT) for image compression, which helps reduce file size and save storage space. However, some information may be lost during the compression process. JPG is supported by most image viewers and editing programs, making it very convenient for online image sharing. However, it does not support transparency and may not be suitable for images with sharp details or text.
One advantage of converting BMP to JPG is that when converting large BMP images to JPG, the compression rate improves, reducing the storage capacity. This allows for faster loading speeds and efficient bandwidth usage when loading images on web pages. Additionally, JPG provides excellent compression rates for color images, saving storage space. However, one should be cautious when converting BMP to JPG as some loss of image quality may occur. JPG uses lossy compression, so detailed information may be lost when saving high-resolution images or images with transparent backgrounds as JPG. Particularly, the quality may decrease when converting images with text or sharp edges to JPG, and alpha channels may not be properly handled when saving semi-transparent images as JPG.
