BMP to JPG converter: free, fast and secure
This free BMP to JPG converter turns your BMP images into JPG files in seconds, right in your browser. BMP files are uncompressed and very heavy. JPG gives you the same picture at a fraction of the size. JPG is accepted by every app, website and upload form, and it keeps photos small enough for WhatsApp, email and online applications.
Unlike most converters, ConvertKaro never uploads your images. The conversion happens on your own device, so it is quicker, there are no file limits, and your photos stay private.
How to convert BMP to JPG in 3 steps
- Add your BMP files. Tap “Select files” or drag and drop one or more .bmp images into the box above. You can also paste a screenshot with Ctrl+V.
- Adjust the options. Set the quality slider. Lower quality means a smaller JPG file.
- Download your JPG. Conversion starts instantly. Download each JPG file, or all of them at once as a ZIP.

What is BMP?
BMP is the classic Windows bitmap format. It stores every pixel without compression, so the quality is perfect but the files are huge: a normal phone photo can become 10–30 MB. Today BMP is mostly used by older Windows programs, embroidery and printing machines, and some industrial software that expects raw pixel data.
What is JPG?
JPG (also written JPEG) is the most widely used photo format in the world. Created in 1992, it uses lossy compression that throws away detail the eye barely notices, which keeps photos small. Every phone, camera, browser, printer and upload form understands JPG, which is why government portals and job sites usually ask for it. The trade-off is that JPG has no transparency, and saving the same file again and again slowly lowers its quality.
When should you convert BMP to JPG?
- Uploading photos to job, exam and government portals
- Sending pictures on WhatsApp and email
- Printing at a local photo shop
- Posting on Instagram, Facebook and marketplaces
Tips for the best JPG results
- For online forms with a size limit, use our Resize Image to 50KB or 20KB tool after converting.
- You can convert many BMP files at once. They are processed one after another and can be downloaded together as a ZIP.
- Keep your original BMP files until you have checked the converted JPG images.
How BMP to JPG keeps your photos and images private
When you add a file to BMP to JPG, it is opened with your browser’s own engine, processed in memory and offered back to you as a download. ConvertKaro never receives a copy. This is why the tool is fast even on 4G, why there is no daily limit, and why it is safe for confidential photos and images like ID proofs, bank documents, contracts and family photos.

Frequently asked questions
Will converting BMP to JPG reduce quality?
JPG uses lossy compression, so a tiny amount of detail is removed. With the quality slider at 90% (our default) the difference is practically invisible, and you can raise it to 100% if you need maximum quality.
Does JPG keep transparency from BMP?
BMP images do not have transparent areas, so there is nothing to lose.
Can I convert multiple BMP files to JPG at once?
Yes. Select or drop as many BMP images as you like. Each one is converted separately, and you can download them all together as a ZIP file.
Is BMP to JPG really free?
Yes, completely free. You can use it as many times as you want, and every option on the page is included at no cost.
Is it safe to use BMP to JPG online?
