The JPE file extension represents a JPEG image, a standard for digital image compression developed by the Joint Photographic Experts Group. It is widely utilized by digital cameras and web applications for storing and transmitting high-quality photographic data with efficient file sizes. While functionally identical to the more common JPG and JPEG extensions, this specific three-letter variant is historically associated with legacy file systems requiring restricted character limits.

Python

with open(file_path, "rb") as f:

Node.js

const signature = Buffer.from([0xFF, 0xD8, 0xFF]);
return buffer.subarray(0, 3).equals(signature);
}
Go
func IsJPE(data []byte) bool {
signature := []byte{0xFF, 0xD8, 0xFF}
if len(data) < 3 {
return false
}
return bytes.Equal(data[:3], signature)
