Convert BMP to JPG.
Shrink a bulky BMP into a JPG right in your browser. The file never uploads and the result opens anywhere.
Why BMP files are so big
BMP is the classic Windows bitmap: a straight dump of every pixel with no compression. That makes it simple, but a single image can be many times larger than it needs to be.
JPG for photos
JPG was built for photographs. It drops detail the eye barely notices, which is why the same picture can shrink so much. It is accepted by every app, website and printer.
Private by design
Your browser does the conversion with its own decoder and canvas. There is nothing to upload and no server copy.
How it works
- 01
Choose your BMP
Pick a file from your device. It is read by your browser and never uploaded.
- 02
Convert in your browser
Your browser decodes the bitmap and saves a high-quality JPG on a canvas.
- 03
Download
Grab your JPG.
Runs in your browser. Your file never uploads
Typically a fraction of the BMP's size
High-quality JPG encoding
No watermark, no signup
Instant, no queue
BMP to JPG: smaller, lossy
JPG uses lossy compression tuned for photographs, so the file gets much smaller while staying visually close to the original. It has no transparency (transparent areas fill with a solid colour), so it suits photos rather than logos or line art.
Common questions
Is it free?+
Yes. Convert BMP to JPG free, with no signup, no watermark and no daily cap, because the conversion runs in your browser.
Is my file private?+
This conversion runs entirely in your browser. Your file never uploads to a server.
How much smaller will it be?+
Usually dramatically smaller. BMP stores every pixel uncompressed, so a photo that is several megabytes as a BMP is often a few hundred kilobytes as a JPG.
Is there any quality loss?+
JPG is lossy, but at the high quality used here the difference is very hard to see in photos. For screenshots with sharp text, BMP to PNG is lossless.
