Format descriptions
JPG — JPG (JPEG) is the most widely used image format in the world. It uses lossy compression to reduce file size, making it ideal for photos and complex images, but it does not support transparency.
BMP — BMP is a lossless raster image format developed by Microsoft. It delivers perfect quality but produces very large files.

What happens when converting JPG to BMP?
The JPG data is decoded inside your browser with WebAssembly and re-encoded to the BMP specification, so no file is ever uploaded to a server. BMP uses lossy compression: the file gets far lighter, but a small amount of fine detail is discarded in the process.

Which format will the result be in?

What happens to transparency when converting to JPG?
JPG does not support transparency. If your image has an alpha channel (for example a PNG or WebP with a transparent background) and you convert it to JPG, the transparent areas are flattened and may appear with a dark or black background. Use PNG, WebP, TIFF or GIF output to preserve transparency.
