About formats

YUV is a raw pixel data format storing images in the Y'UV color model, where image data is separated into a luminance component (Y', representing brightness) and two chrominance components (U/Cb and V/Cr, representing color difference signals). The YUV color model originated with analog color television broadcasting — specifically the NTSC system adopted in 1953 and the PAL system in 1967 — where backward compatibility with existing black-and-white receivers required separating brightness from color information. In digital imaging, the ITU-R BT.601 standard (1982) formalized the digital YCbCr encoding derived from the analog YUV model, defining the conversion matrices and sample precision used by virtually all digital video and broadcast systems. YUV raw files contain no header, compression, or metadata — they are flat sequences of luminance and chrominance samples in a specified ordering (4:4:4, 4:2:2, 4:2:0, or other subsampling ratios), requiring external specification of dimensions, bit depth, and subsampling scheme. The 4:2:0 subsampling mode (where chrominance has half the horizontal and half the vertical resolution of luminance) is particularly common, used by H.264, H.265, AV1, and most consumer video codecs. One advantage is direct video pipeline compatibility: YUV data is the native input format for video encoders, hardware display controllers, and camera sensor ISPs, making raw YUV the most direct representation for frame-accurate video processing and analysis. The perceptual efficiency of the YUV color model is another fundamental strength — separating luma from chroma enables effective subsampling that halves or quarters the color data with minimal visible impact. YUV data is processed by FFmpeg, ImageMagick, and all video processing tools.
Developer: ITU-T (CCIR)
Initial release: 1982
JBG is a file extension for images compressed using the JBIG (Joint Bi-level Image experts Group) standard, formally ITU-T Recommendation T.82, completed in 1993 as a successor to the Group 3 and Group 4 fax compression standards. JBIG compression is designed for bi-level (black and white) images but can also handle grayscale and limited-color images by encoding each bit plane separately. The algorithm uses a form of arithmetic coding guided by an adaptive context model: for each pixel, the encoder examines a template of surrounding already-coded pixels to build a probability estimate, then feeds this estimate to a QM-coder (a variant of the Q-coder arithmetic coder) that produces a highly efficient binary output. JBIG achieves 20-40% better compression than Group 4 on typical document images, with the improvement being even larger on halftoned photographs and images with gradual density transitions where Group 4's simple run-length approach is less effective. The standard supports progressive encoding, where a low-resolution version of the image is transmitted first and progressively refined — useful for fax-like applications where the receiver can begin displaying the image before the full-resolution data arrives. One advantage is superior compression of documents containing halftone images: newspapers, magazines, and marketing materials that mix text with photographic halftones compress dramatically better with JBIG than with Group 3/4. The standard's ITU-T backing ensures it is implemented in document imaging hardware and software worldwide. JBG files are supported by ImageMagick and various document imaging tools.

Frequently Asked Questions

Why convert YUV to JBG?

YUV data from video encoding, broadcast, and processing pipelines becomes universally viewable once converted to JBG format.

How do I open JBG files?

Use JBIG viewers, fax systems to view JBG files. This format enjoys broad software support on all major platforms.

Is YUV to JBG conversion accurate?

Convertio preserves the visual content from your YUV data during conversion — the JBG output faithfully represents the source.

Is my YUV data kept private?

Convertio deletes uploaded YUV files immediately after conversion. JBG outputs are automatically purged within 24 hours.

Do I need to install anything?

Convertio is fully browser-based. No desktop software, plugins, or extensions are necessary for YUV to JBG conversion.

What quality can I expect from JBG output?

Expect solid results — JBG delivers efficient bi-level image compression, and the converter maximizes output fidelity.
