Does converting BMP to JPG reduce image quality?

JPG uses lossy compression, so there is some quality trade-off, but at the default quality setting the difference is generally not visible to the eye. You can re-convert at a higher quality if you notice artifacts.

Is my image uploaded to a server?

No. The conversion from BMP to JPG happens entirely on your device using your browser's built-in image processing — your files are never uploaded anywhere.

BMP and JPG are both common image formats, but they serve different purposes. BMP is typically used for Windows-native applications, while JPG is best known for photographs. Converting from BMP to JPG takes seconds with this tool — just drop your files below, and the conversion happens instantly on your own device.

A raw BMP screenshot or scan can be ten times larger than it needs to be for sharing — converting to JPG makes it small enough to email or post with no noticeable quality loss.

JPG remains the most universally compatible photo format — converting to JPG is a safe choice when you need a file that will open correctly in absolutely any app, browser, or printer.
