This free JPG to BMP converter turns your .jpg images into .bmp files. JPG is universal and lossy. Every re-save degrades it a little further, so it is a poor place to keep an image you will edit again.
This conversion tries your browser first. If your browser cannot decode or encode the selected format, it falls back to our server. Server conversions are processed in memory and returned without storing the file.

- Download each converted file, or pick them up one by one from the list.
What changes when you convert JPG to BMP
BMP is lossless, but it cannot restore what JPG already discarded. The output will be larger than the input and no sharper — you are preserving the current state, not recovering the original.
JPG and BMP compared
| JPG | BMP | |
|---|---|---|
| Full name | JPEG — Joint Photographic Experts Group | Windows Bitmap |
| Extension | .jpg, .jpeg | .bmp |
| MIME type | image/jpeg | image/bmp |
| Compression | Lossy | Lossless |
| Transparency | No | No |
JPG: Lossy compression tuned for photographs, supported by every device made in the last thirty years. No transparency, and repeated re-saving degrades the image, so keep an original.
BMP: Uncompressed raw pixels, which makes the files enormous and the format trivial to parse. Mostly encountered coming out of legacy Windows software and scanners.
Frequently asked questions
How do I convert JPG to BMP?
Drop your .jpg file onto the box on this page and the .bmp file is ready to download in a second or two. There is no signup, no email, no watermark and no file limit beyond about 4 MB per upload — larger images are re-encoded smaller in your browser first, and the page says so when that happens.
Is this JPG to BMP converter free?
Yes, completely, with no account, no trial and no watermark on the output. There is nothing to buy on this page: choose a file, convert it and download the result.
Are my files uploaded anywhere?
The converter tries your browser first. If your browser cannot handle the format, the file is sent to our conversion server and processed in memory. The result tells you where the conversion ran. Use a desktop tool if you must avoid all uploads.
Will converting to BMP reduce the quality?
BMP is lossless, but it cannot restore what JPG already discarded. The output will be larger than the input and no sharper — you are preserving the current state, not recovering the original.
Can I convert several JPG files at once?
Yes, up to 20 files in one go. Drop them all onto the box together and each one appears in the results list with its own download button.
