Convert old BMP bitmaps to compact JPG in your browser. BMP is an uncompressed Windows raster format — a photo that is 10 MB as BMP can be under 1 MB as JPG. This converter is especially useful for screenshots and images exported from Paint, legacy engineering software, or older Windows applications. Processed locally, nothing uploaded.

Common questions
How much smaller is JPG?+
Dramatically — uncompressed BMPs frequently shrink by 90% or more when converted to JPG.
Quality loss?+
JPEG is lossy but at quality 90 the difference is not visible for normal viewing and sharing.
Private?+
Yes — nothing is uploaded. The conversion happens entirely in your browser.
What if my BMP is very large?+
BMP files can be hundreds of megabytes. The browser handles them locally, so conversion speed depends on your device memory — give it a moment for very large files.
