BMP (Bitmap) is an uncompressed raster image format developed by Microsoft. It stores raw pixel data with no compression, resulting in large file sizes.
JPG files are much smaller than BMP. Converting to JPG makes the image easier to share, upload, and use on the web.
Yes. JPG is lossy, so some image data is discarded during compression. At high quality settings the difference is minimal.
Yes. JPG is the most universally supported image format and opens natively on Windows, macOS, iOS, Android, and all web browsers.
A quality setting of 80 to 85 percent gives a good balance between file size and visual quality for web images. Below 70 percent you may notice visible compression artefacts.
Lower the quality setting during conversion. Alternatively, use our Image Compressor tool after converting to reduce the file size to a specific target.
The tool converts one file at a time. For batch conversion, use a desktop tool like IrfanView or XnConvert which support bulk BMP to JPG conversion.
