BMP to JPEG Converter
Convert BMP images to JPEG in your browser. Nothing is uploaded, nothing is watermarked, and every option is available to everyone.
Drop your images here
or click to browse your files
Up to 200 files at a time, 200 MB per file. These limits protect your browser from running out of memory, they are not commercial restrictions.
This image is being read and converted by your own browser. It is never uploaded.
How to do it
Step 1: Drop your BMP files onto the page, or click to choose them. You can also paste an image straight from the clipboard.
Step 2: JPEG is already selected as the output. Adjust the quality or size if you want to.
Step 3: Press Convert. The work happens in your browser, so nothing is uploaded.
Step 4: Download the JPEG file, or download everything as a ZIP if you converted several.
Why convert BMP to JPEG?
BMP files store pixels with almost no compression, so this conversion usually shrinks the file dramatically.
BMP is rarely accepted by websites and messaging apps, which is the other common reason for converting it.
JPEG also brings its own advantage here: photographs compress dramatically, often to a tenth of a lossless file.
BMP compared with JPEG
The two formats are built for different jobs, and the differences decide whether this conversion is the right one. BMP and JPEG differ mainly in these respects.
| Aspect | BMP | JPEG |
|---|---|---|
| Compression | Usually none at all. | Lossy. Detail is discarded permanently, controlled by a quality setting. |
| Transparency | Sometimes, in 32-bit files, though many programs ignore it. | No. |
| Software support | Good on Windows, patchier elsewhere. | Universal. |
| Best suited to | Output from older Windows software, scanners and some scientific tools. | Photographs, camera output, and anything that has to open anywhere. |
Questions
Are my BMP files uploaded anywhere?
No. The conversion runs entirely in your browser. Your files are read from your device and never sent to a server, because this site has no server that receives them.
What happens to transparency when converting BMP to JPEG?
JPEG cannot store transparency, so transparent areas are filled with a background colour. You choose the colour, and the preview shows exactly how the result will look before you download it.
Does converting to JPEG lose quality?
Yes. JPEG is a lossy format, so some detail is discarded permanently. The quality setting controls how much: at 80 or above the difference is rarely visible, and lower values trade visible detail for a smaller file.
Can I convert several BMP files at once?
Yes. Add as many as you like, convert them together, and download the results individually or as a single ZIP. Progress is shown per file and overall.
Is there a file size limit?
There is no commercial limit and no account. There are technical limits, because a browser has finite memory: very large images are flagged before conversion, and the tool says plainly when a device may struggle rather than freezing.
Does it cost anything?
No. Every format and every feature is available to everyone. There is no paid tier, no watermark and no sign-up.
