BMP to JPG Converter

Convert large BMP images to much smaller JPG files.

BMP is an old, usually uncompressed Windows image format, so BMP files are often very large. Converting them to JPG typically cuts the size dramatically with no visible difference, and makes them easy to email, upload and share. Convert one BMP or many, set the quality, and download them singly or as a ZIP. Files are converted in your browser and never uploaded, so photos and documents stay on your device.

FAQ

Why are BMP files so big?

Most BMP files store every pixel without compression: three bytes per pixel for colour images. A 1920 × 1080 picture is about 6 MB as a BMP, but often a few hundred KB as a JPG.

Will I lose quality?

JPG is lossy, but at 90% quality the difference is very hard to see. For screenshots with sharp text, PNG keeps every pixel exactly.
