Quick answer

BatchSet converts BMP to JPG free and entirely in the browser: BMP decodes natively in the browser canvas, so nothing is uploaded and no account is needed. A BMP stores pixels uncompressed (a 1920x1080 image is about 6 MB whatever it shows), so the JPG is dramatically smaller. The pixel size is kept, quality is adjustable, and many BMP files convert at once with a ZIP download.

How to use the BMP to JPG

Three quick steps — free, private, right in your browser.

1

Add your BMP files

Drop one or many .bmp files, or click to pick them.

2

Set the quality

JPG trades a little detail for a much smaller file. The default suits photos and screenshots alike.

3

Convert and download

Each file is converted in your browser. Save them one by one or as a ZIP.

Frequently asked questions

Why is a BMP so big?+

A BMP usually stores every pixel with no compression at all, so a 1920 x 1080 image takes about 6 MB whatever is in it. JPG compresses that, which is why the same picture lands in the tens or hundreds of KB.

Is BMP to JPG free here?+

Yes. Browsers decode BMP natively and write JPG natively, so the conversion runs on your own device with no account and no watermark.

Will it lose quality?+

JPG is lossy, so some fine detail goes. At the default quality that is hard to see on a photo; on a screenshot with sharp text, PNG is the better target.

Does the image stay the same size?+

Yes. The pixel dimensions are unchanged unless you resize it yourself.

Can I convert many BMP files at once?+

Yes. Add the whole set and download the results as a ZIP.
