How to convert JPG to BMP
Converting JPG to BMP stops any further quality loss, which is useful if you plan to edit the image further.
- Click the Choose Files button and select your JPG files.
- BMP is already selected as the output. Click the gear if you want to adjust quality or resize.
- Click Convert, then hit Download to save your BMP files, or grab them all as a ZIP.
Built for JPG files
Drop in as many JPG images as you like and they all come out as BMP. You can also change the output on any individual file if you need a mixed batch.
Keep the quality
Adjust quality per file and resize on the way through. Formats without transparency get a clean white matte instead of the black edges most converters leave behind.
Nothing is uploaded
Your files are read and written by your own browser. They are never sent to a server, so there is nothing to delete afterwards and no size or file-count limit.
More image tools
Three separate tools, all running the same way — entirely inside your browser, with nothing uploaded.
The compressor is the one to use when you want a smaller file without changing its format — it can hit an exact target file size, which the converter cannot. The resizer handles exact dimensions and ready-made presets for Instagram and YouTube, including common sizes like 1920×1080 and 1080×1080.
A few things are built into this converter and need no separate tool:
- Compress without converting — pick the same format as your input and lower the quality slider to shrink a file while keeping its type.
- Resize — open the gear on any file and set a maximum width; the height follows automatically.
- Images to PDF — choose PDF as the output to turn a photo or scan into a document.
- Make a favicon — choose ICO as the output to produce a browser icon from any square image.
What is a JPG file?
JPG stands for Joint Photographic Experts Group. JPG is the most widely supported image format in existence. It uses lossy compression, discarding detail the eye is unlikely to notice in order to produce a much smaller file.
JPG cannot store transparency, and repeatedly re-saving a JPG degrades it a little each time.
What is a BMP file?
BMP stands for Bitmap. BMP stores pixels with no compression at all. That makes it simple and completely lossless, and it is still used by some Windows software and older imaging tools.
Files are very large — often ten times the size of the same image as PNG — and it has no place on a modern website.
JPG to BMP: expect the file to grow enormously
This conversion makes the file much bigger and the picture no better. BMP stores uncompressed pixels, so a 2 MB JPG can emerge as a 40 MB BMP containing exactly the same visual information, compression artifacts included.
There are legitimate reasons to want one. Some older Windows applications, industrial and laboratory instrument software, embedded display systems and certain game modding tools accept BMP and nothing else, because reading the format requires no decoding library at all. If something on your machine demands a .bmp, this produces one. Otherwise PNG gives you the same lossless result at a fraction of the size.

Frequently asked questions
Is BMP better quality than JPG?
BMP is lossless, but converting a JPG to BMP does not recover anything the JPG already discarded. You get a perfect, very large copy of a lossy image. Converting to PNG achieves the same thing in far less space.
Will converting JPG to BMP improve the quality?
No. Detail already discarded by JPG cannot be recovered. What converting to BMP does is stop any further loss, so the image will not degrade again on the next save.
Is there a limit on file size or how many files I can convert?
No. Conversion runs inside your browser rather than on a server, so there is no upload, no queue and no cap. Very large images may simply take a moment on a slower device.
Are my JPG files uploaded anywhere?
No. Your files are read and written by your own browser and never leave your device. You can disconnect from the internet once the page has loaded and the converter will still work.
