Lossless JPEG may refer to:
- The standard lossless modes of the original JPEG format
- The JPEG-LS format (which supports both lossless and lossy compression)
- A lossless JPEG transformation. A lossless JPEG transformation is not a format; it refers to the process of editing (e.g. rotating or cropping) a lossy JPEG image without causing any additional loss of image quality.
Less-likely things it could mean:
- Only the lossless form of JPEG-LS
- The nonstandard SmartScale features promoted by the IJG libjpeg software, when used to achieve lossless DCT compression
- The collection of all formats that are lossless and have JPEG in their name, which could even include some forms of JPEG 2000 and JPEG XR
