About the BMP to JPG Converter
The BMP to JPG Converter turns Bitmap (BMP) images into JPEG (JPG) files right inside your web browser. Shrink huge uncompressed BMP files into small JPG images that are easy to email and upload.
BMP is an uncompressed Windows bitmap format. It keeps full quality but produces very large files, and it is rarely accepted by websites or social networks.
JPG (or JPEG) is the most widely used photo format in the world. It uses lossy compression to keep photographs small, which makes it perfect for cameras, websites and messaging, but it cannot store transparent areas and loses a little quality every time it is re-saved.
JPG uses lossy compression, so use the quality slider to balance file size and detail; 85–92% looks virtually identical to the original. BMP images have no transparency, so the result looks exactly like the original. You can convert dozens of images at once, optionally limit the maximum width to shrink large photos, and download everything as a single ZIP file. Because the conversion runs locally on your device, your pictures are never uploaded to a server.
How to use the BMP to JPG Converter
- Drop your BMP files into the upload area, click to browse, or paste an image.
- Adjust the quality, background color or maximum width if needed.
- Wait a moment while each image is converted to JPG on your device.
- Download files individually or click Download all (ZIP).
