Convert BMP to JPG
An uncompressed BMP becomes a JPG many times lighter, with the same pixels and a file that fits in an email.
Convert BMP to JPG because of the weight: an uncompressed picture takes megabytes where a couple of hundred kilobytes would do, and neither an upload form nor a mailbox wants to take it.
What happens when you convert BMP to JPG
BMP stores every dot as its own number, so the file size depends on the pixel count alone. JPG compresses the image with losses and weighs many times less for the same picture.
Width and height in pixels stay as they were, and nothing is shrunk or cropped. What changes is the way the data is kept, and at high zoom you can spot faint halos along sharp edges and flat fills.
- Photos and scans look the same after compression, with the difference visible only under heavy zoom.
- Screenshots and diagrams with thin lines suit JPG less well, since the outlines blur.
- Converting an already compressed file again adds fresh losses, so keep the original.
The way back is the JPG to BMP converter. If you want crisp lines and a small file at once, take the BMP to PNG converter.
How to convert
- Upload your BMP file to this page.
- Check that the target format is JPG.
- Start the conversion and wait for the finished file.
- Download the picture and open it before sending.
Frequently asked questions
Does the pixel size change?
No. Width and height stay the same, and only the weight of the file goes down.
Is quality lost?
Some data is dropped during compression. On a photo it goes unnoticed; for a diagram with thin lines PNG is the better target.
