How to Convert BMP to JPG?
Nothing is uploaded. The bmp file is decoded and re-encoded as jpg inside this tab.
Add your BMP files
Drag them in or use Choose Files. Batches are fine.
JPG is already selected
85 to 90 is the sweet spot. This is the bitmap's first lossy encode, so quality holds up better than a re-encode would.
Convert and download
Everything runs locally, so the jpg file saves straight to your device.
Why Convert BMP to JPG?
A 1920×1080 BMP file can be 6MB or more. Converting to JPG at 85% quality typically reduces that to under 300KB, a 95%+ reduction with no visible quality difference. Essential for sharing, emailing, or publishing BMP images on the web.
About BMP
BMP (Bitmap) is an uncompressed Windows image format. BMP files contain raw, uncompressed pixel data, making them extremely large compared to modern formats. A full HD BMP image can be 5, 8MB.
About JPG
JPG's efficient lossy compression makes it the best choice for reducing BMP file sizes while maintaining visual quality. JPG is universally supported and the standard format for web, social media, and email.
What Happens to Transparency
Not a factor. Standard 24-bit BMP files have no alpha channel, and neither does JPG, so nothing is lost in the move.
File Size: What to Expect
This is the largest saving available here. A 5.93 MB 1920x1080 BMP typically drops to between 200 and 400 KB at 85% quality, a reduction of 93 to 97%, with no difference visible at normal viewing size.
When Not to Convert BMP to JPG
If the bitmap is a screenshot, a diagram, or anything containing small text or flat colour, convert to PNG instead. JPG will produce visible ringing around the hard edges, and PNG gives you a lossless result that is still far smaller than the BMP.
How the Conversion Works
The bitmap is decoded to raw pixels and re-encoded with the browser's JPEG coder. Since BMP is uncompressed, this is the first lossy step the image has ever been through, so quality at 85% and above holds up excellently.

How much smaller will my BMP get?
Typically 93 to 97% smaller at 85% quality. Uncompressed bitmaps are the most compressible input there is.
Is JPG the right choice for my bitmap?
For photographs, yes. For screenshots, diagrams or anything containing text, convert BMP to PNG instead to avoid JPG's edge artifacts.
Are my BMP images uploaded to a server?
No. The conversion runs entirely in your browser. Your BMP files never leave your device and are never sent anywhere.
