Transform your JPG files into BMP format instantly within your browser.
JPG is the most common file extension for images compressed with the JPEG standard, published in 1992. It applies lossy compression based on the discrete cosine transform, splitting images into small blocks and discarding visually insignificant detail to shrink file size. The compression level is adjustable: higher quality keeps more detail at a larger size, while lower quality trades visible artifacts for a much smaller file. JPG supports 24-bit true color and embeds Exif metadata such as camera model and capture date. Its biggest strength is universal compatibility — it is the native output of virtually every camera and phone, and opens in every browser, viewer, and operating system without exception.
BMP (Bitmap, also called Device Independent Bitmap) is a raster format created by Microsoft for early versions of Windows around 1990. Most BMP files store pixel data with little to no compression, so file sizes scale directly with image dimensions and color depth rather than actual visual complexity. This simplicity made BMP easy for any program to read and write reliably, but it also means a BMP is often 5-10 times larger than an equivalent JPG or PNG. It's still occasionally produced by legacy Windows tools, screenshot utilities, and some scientific or industrial imaging software that prioritize a simple, uncompressed structure.
