Convert old BMP files to modern JPG. Dramatically smaller files — typically 90%+ size reduction with no visible quality loss.
BMP is a legacy Windows format with essentially no compression — every pixel is stored uncompressed. A photographic BMP can be 10–50× larger than the same image as JPG. Converting to JPG is one of the most dramatic file-size reductions you can do.
BMP files often appear from old Windows software, screenshots from legacy programs, or specific industrial systems. Converting them to JPG makes them practical to email, store, and share.
You almost always want to convert BMP to JPG when modernizing files. Reasons include massive size reduction (a 30 MB BMP might become 1 MB as JPG), universal compatibility (JPG works everywhere; BMP support is patchy on mobile and modern web), and practical sharing (BMP attachments are often too large to email or upload).
Most online BMP to JPG converters require uploading your files to their servers. We don't. The conversion happens entirely in your browser using the native Canvas API. Your images never travel over the network.
Open your browser's developer tools, watch the Network tab, and convert a file — you'll see code being downloaded but no images being uploaded. Read our take on why client-side image processing matters.
