Convert BMP images to JPG without uploading them.

Convert a BMP or bitmap file to JPG for a smaller, more widely supported sharing copy. Choose the JPEG quality after checking the decoded image. The output is a single opaque JPG with the same pixel dimensions; the original BMP remains unchanged and conversion runs in this browser.
Benefits of this conversion
- Create a real JPG file for a different app or workflow.
- Adjust output quality before downloading.
- Preview the converted BMP image and keep the source untouched.
How it works
- Choose a valid BMP file.
- Adjust JPG quality and choose the background used for transparent pixels.
- Convert, preview and download the JPG file.
BMP compared with JPG
BMP is a raster bitmap that is often large and less convenient for everyday sharing.
JPG is a widely compatible, lossy photo format without transparency.
Bitmap input and JPEG output
BMP files often store raster pixels with little or no space-efficient compression. JPG can be substantially smaller for photographs, but it achieves that by discarding some visual information during encoding.
JPG is opaque and lossy, so it is not a pixel-perfect archive replacement for BMP. Keep the source when exact raster data matters and use the new JPG as the compatible delivery copy.

Private by design
Your files stay on your device. Processing starts only when you choose an image, and nothing is stored on our servers.
Frequently asked questions
Are my images uploaded?
No. Processing happens locally in your browser, so your image files never leave your device.
Will converting to JPG change image quality?
You control the output quality. A higher setting preserves more detail and creates a larger file.
What does BMP to JPG conversion create?
It decodes the source and creates a new, genuine JPG file.
Can I convert several files at once?
No. This converter processes one source image at a time.
How are quality and file size handled?
JPG uses lossy compression: raising quality preserves more detail but usually creates a larger file. BMP transparency cannot be stored in JPG, so transparent pixels use the background selected in the converter. Pixel dimensions stay unchanged.
What happens to transparency?
JPG has no alpha channel. Transparent pixels decoded from BMP use the background selected in the converter.
