JPEG XT 是一種基於並兼容JPEG標準(ISO / IEC 10918-1和ITU Rec.T.81)圖像壓縮標準。 相比於 JPEG,JPEG XT 支援更高的色彩深度,高動態範圍成像和浮點數編碼,無損編碼,alpha頻道編碼。JPEG XT 向下相容 JPEG / JFIF 格式。

T.81). JPEG XT extends JPEG with support for higher integer bit depths, high dynamic range imaging and floating-point coding, lossless coding, alpha channel coding, and an extensible file format based on JFIF. It also includes reference software implementation and conformance testing specification. JPEG XT extensions are backward compatible with base JPEG/JFIF file format - existing software is forward compatible and can read the JPEG XT binary stream, though it would only decode the base 8-bit lossy image.ld only decode the base 8-bit lossy image.
