Convert BMP to JPG
Updated Jul 2026
BMP is an old Windows image format that stores pictures uncompressed, which makes the files huge. To convert BMP to JPG, open the file in a converter and export it as JPG, which shrinks it down to a fraction of the size. You can do this right on your own computer, so the image never has to be uploaded anywhere.

How to convert BMP to JPG
- Open Morphjet and drag in the BMP file, or a whole folder of them, at once.
- Choose JPG as the output format, and set a quality level if you want an even smaller file.
- Convert. The JPGs are written next to your originals, and nothing leaves your machine.
BMP vs JPG: what actually changes
| BMP | JPG | |
|---|---|---|
| File size | Very large, stored uncompressed | Much smaller, often a tenth the size or less |
| Quality | Lossless, pixel-perfect | Very good, with a small one-time loss on export |
| Opens everywhere | Mostly Windows apps, rarely used on the web | Yes, universal support |
| Good for sharing or web use | No, too heavy to email or upload comfortably | Yes, built for it |
| Metadata | Rarely stores camera or location info | Can carry EXIF data if present in the source |
When to convert, and when not to
Convert BMP to JPG when you need to email, upload, or post an image and the BMP file is too large to work with, or when a site or app simply won't accept BMP.
Keep the BMP original if you need pixel-perfect, uncompressed data for something like technical imaging or archival scans, since JPG's compression throws away detail you can't get back.
Why not just use an online converter?
BMP files are often old scans, screenshots, or exports sitting on a Windows machine, and running them through an online converter means uploading that image to a stranger's server just to shrink it. Converting on your own computer skips that step entirely. The file gets smaller and stays exactly where it was.
Questions
Does converting BMP to JPG lose quality?
Yes, a small amount. BMP stores every pixel with no compression, while JPG compresses the image to save space. At a reasonable quality setting the loss is hard to notice, but it's not perfectly lossless like the original.
Why are BMP files so much bigger than JPG?
BMP doesn't compress the image data at all, so every pixel is stored in full. JPG applies compression that removes detail the eye barely notices, which is why the same picture can be ten times smaller or more as a JPG.
Will converting to JPG keep any metadata from the BMP?
BMP files usually don't carry camera or location metadata to begin with, so there's typically nothing to lose. If the source does have embedded data, it can carry over to the JPG.
Can I convert a whole folder of BMP files at once?
Yes. Morphjet lets you drag in a folder of BMP files and convert them all to JPG in one pass, which is handy for old batches of scans or screenshots.
Can I convert BMP to JPG without uploading the file?
Yes. A desktop app like Morphjet converts the file on your own computer, so it never has to travel over the internet. You can do it with your wifi off.
