What is JPG to BMP Converter?
JPG to BMP Converter turns compressed JPEG photos into BMP bitmap files. BMP stores decoded pixel data in a simple bitmap structure, which can help with older software, hardware displays, and workflows that expect BMP input. The tool decodes the JPG in the browser and exports a BMP copy.
How does JPG to BMP Converter work?
This tool decodes the JPG source, draws the pixels to canvas, and writes a BMP output file. The BMP result can be much larger because it does not use JPG-style lossy compression. Existing JPG compression artifacts remain because they are part of the decoded source pixels.

Common Use Cases
Image editing preparation
Convert JPG to BMP for editing in tools that handle uncompressed bitmaps more efficiently.
Legacy software compatibility
Transform JPG images into BMP for use in older applications that do not support JPG format.
Pixel-level analysis
Convert JPG to BMP for exact pixel data access without compression artifacts affecting analysis.
Embedded systems
Generate BMP files from JPG photos for hardware displays and embedded systems that require raw bitmap data.
How to Use This Tool
Upload an image
Drag and drop a JPG file or select one from your device.
Convert
Click Convert. The tool processes the image and generates a BMP file.
Download
Save the converted BMP image to your device.
Pro Tips
- 1
BMP files are uncompressed and will be much larger than the JPG source, often 10x or more.
- 2
JPG compression artifacts will be preserved in the BMP output since the decoded pixels include them.
- 3
Use BMP when you need raw pixel data without any further compression.
- 4
For a smaller uncompressed format, consider PNG which uses lossless compression.
Frequently Asked Questions
Will the quality change?
BMP is uncompressed, so the decoded pixel data from the JPG is preserved exactly. However, JPG compression artifacts from the original are retained.
Is my image uploaded to a server?
No. The JPG is decoded, converted, and exported in the browser.
What is the maximum file size?
The tool supports images up to 50MB. Since BMP is uncompressed, the output file may be very large.
Does BMP support transparency?
No. Both JPG and BMP are opaque formats, so no transparency is involved in this conversion.
Can I convert multiple images at once?
Yes. Upload multiple files and the tool converts all of them.
