This free BMP to JPG converter turns your .bmp images into .jpg files. BMP turns up from legacy Windows software and scanners. It stores raw uncompressed pixels, so files are enormous for what they contain.
Because browsers cannot write JPG, this one runs on our server: the file is converted in memory and sent straight back. It is never written to disk, never logged and never stored.
How to convert BMP to JPG
- Drop your BMP files onto the box above, or click it to choose from your computer. Up to 20 at once.
- Set the quality if you want to trade size against detail. 85 is a good default; below about 70 the loss starts to be visible.
- Download each converted file, or pick them up one by one from the list.
What changes when you convert BMP to JPG
BMP is lossless and JPG is not, so this conversion discards some image data permanently. At quality 85 the difference is invisible for photographs; for screenshots, text and line art it shows as faint haloing around edges.
BMP and JPG compared
| BMP | JPG | |
|---|---|---|
| Full name | Windows Bitmap | JPEG — Joint Photographic Experts Group |
| Extension | .bmp | .jpg, .jpeg |
| MIME type | image/bmp | image/jpeg |
| Compression | Lossless | Lossy |
| Transparency | No | No |
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.
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.
Frequently asked questions
How do I convert BMP to JPG?
Drop your .bmp file onto the box on this page and the .jpg 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 BMP to JPG converter free?
Yes, completely, with no account, no trial and no watermark on the output. We are a consultancy and these tools exist because we needed them ourselves; there is nothing to buy on this page.
Are my files uploaded anywhere?
This one has to run on our server, because browsers cannot write JPG. The file is converted in memory and returned immediately — it is never written to disk, never logged and never stored. If that is not acceptable for your file, use a desktop tool instead.
Will converting to JPG reduce the quality?
BMP is lossless and JPG is not, so this conversion discards some image data permanently. At quality 85 the difference is invisible for photographs; for screenshots, text and line art it shows as faint haloing around edges.
Can I convert several BMP 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.
