What is a JPEG file?
JPEG is a raster image format utilizing lossy compression defined by the Joint Photographic Experts Group standard (ISO/IEC 10918-1). It employs discrete cosine transform (DCT) to convert spatial image data into frequency domain coefficients, which are then quantized to reduce high-frequency information that is less perceptible to the human eye. The format supports 24-bit color depth (TrueColor) and is the de facto standard for digital photography and web images due to its adjustable compression ratios, which balance visual fidelity against file size storage requirements.
How to open a JPEG file
Native support for JPEG is embedded in the kernel or core frameworks of virtually all consumer operating systems (Windows, macOS, Android, iOS, Linux). Files open instantly in default applications such as Windows Photos and Apple Preview. For advanced manipulation of compression artifacts or metadata (EXIF/IPTC), professional software like Adobe Lightroom or open-source alternatives like GIMP and ImageMagick are utilized. All web browsers render JPEG content natively.
