Convert BMP to JPG Online Free
BMP files store images without any compression, so they are often enormous: a single scanned page or screenshot can take 10 MB or more. Converting them to JPG usually makes them 80 to 95 percent smaller.
BMP images often come from Microsoft Paint, older scanners, and legacy software. As JPG, they can be emailed, uploaded to websites, and opened on any phone.
Use a quality of 90 for scans you want to keep, or lower it for images that only need to be viewed on screen.

One Converter for Every Image Format
Phones, cameras, websites, and design apps all use different image formats. Instead of a separate tool for every pair, ToolCube converts any supported format to any other in one place: open an iPhone HEIC and save a JPG, turn a logo PNG into an ICO favicon, or shrink a large PNG into a WebP for your website.
Fast and Safe on Your Own Device
The conversion runs in a background process inside your browser, so the page stays responsive even with large photos and long batches. Decoders for formats such as HEIC, AVIF, and TIFF load only when you need them, and nothing is ever sent to a server.
FAQ
Frequently Asked Questions
Answers to common questions about converting BMP to JPG.
Why are BMP files so large?
BMP stores every pixel as raw colour values with no compression. JPG compresses the image, which reduces the size dramatically with little visible change.
Will converting BMP to JPG reduce the quality?
JPG compression is lossy, but at quality 85 to 90, the result looks the same as the BMP for photos and scans. For images with tiny text, consider PNG instead.
Can I convert BMP files from Windows Paint?
Yes. Standard 24-bit and 32-bit BMP files from Paint and other Windows programs are supported.
