How JPG to BMP Conversion Works
JPG is an image format: it uses lossy DCT compression that permanently discards fine pixel detail to achieve small file sizes, ideal for photographs. BMP is an image format that stores uncompressed pixel data in a simple row-by-row grid, resulting in large file sizes but zero quality loss. This conversion changes the file's encoding, compression method, and supported feature set. Colour profiles and orientation metadata are preserved in the output. Converting between these two formats is common when the source application does not support BMP natively or when the target platform only accepts BMP. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
