BMP is the uncompressed Windows bitmap format. Every pixel is stored as-is, so files are very large, but some older programs and devices still require it. JPG is the most widely supported photo format. It uses lossy compression, so photos are small, and every device, app and website can open it.
Converting to JPG gives you a file that opens anywhere and is easy to email, upload and print. The conversion happens entirely in your browser, so your files are never uploaded and there’s no size limit beyond your device’s memory.
How to convert BMP to JPG
- Add one or more BMP files.
- They’re converted to JPG automatically.
- Download them individually or as a ZIP.
Questions
Is BMP to JPG conversion free?
Yes, completely free with no limits, sign-up or watermark.
Are my files uploaded?
No. Conversion runs on your own device, so your files stay private.
What happens to transparent areas?
JPG can’t store transparency, so they’re filled with a colour you choose (white by default).
