How to convert JPG to BMP

Choose a JPG, optionally resize it, and download a newly encoded BMP without uploading the image.

Select an image from your device or drag it into the upload area.

Resize the image if you need different output dimensions.

Review the preview and file size, then save the converted image.

This free online JPG to BMP converter includes the following controls and output tools:

Private browser conversion. The image is processed locally and is not uploaded.
Custom dimensions. Set an exact width and height, lock the aspect ratio, and prevent accidental enlargement.
Lossless output encoding. The visible decoded pixels are written without an additional lossy quality setting.
Before-and-after preview. Review the original and converted image, output dimensions, format, and file size.
File-size comparison. See the original and converted sizes and the percentage change.
Custom filename. Rename the converted file before downloading it.
Metadata-free export. The newly encoded BMP does not copy source metadata.

BMP may be required by older Windows software, embedded tools, or a legacy image workflow.

BMP files are usually much larger than JPG because they store uncompressed pixel data.

The BMP stores the decoded JPG pixels without adding new lossy compression, but it cannot restore detail already lost in the JPG.

The output is a 32-bit bitmap. A PNG copy is used for the browser preview, and source metadata is not retained.

Is this JPG to BMP converter free?

Yes. Convert one JPG at a time.

Will quality improve?

No. BMP cannot restore details removed by JPG compression.

Why is BMP larger?

The output stores four bytes per pixel with no image compression.

Why is the preview PNG?

Browser BMP display varies, so a PNG copy provides a reliable preview.

Is my JPG uploaded?

No. Conversion happens locally.
