When this tool is useful
BMP files can be relatively large because they often store pixel data with little compression. JPEG can reduce file size, but it is lossy and does not preserve transparency, so check the saved image before using it in a design.
How to use it
- Select a BMP or bitmap image from your device.
- Choose the available JPG quality setting and run the conversion.
- Preview or download the JPEG copy, keeping the original until you check it.
Common uses
- Sharing bitmap images with apps that prefer JPEG
- Creating a smaller copy for a website or email
- Converting an older BMP graphic for common image workflows

Tips for a reliable result
JPG is smaller for many photos, but it uses lossy compression and cannot keep transparency. Keep the original BMP if you may need its uncompressed pixels later.
Frequently asked questions
Is BMP to JPG the same as bitmap to JPEG?
Yes. BMP is commonly called a bitmap image, and JPG/JPEG is the output format used here.
Will converting BMP to JPG reduce file size?
It often does, depending on the image and quality setting. JPEG uses lossy compression, so the output may not be suitable when every original pixel matters.
Does JPG preserve transparent pixels?
No. JPEG does not support transparency. Transparent areas are rendered against the browser canvas background during conversion.
