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.

TCR (Text Compression for Reader) is a compressed plain-text ebook format developed by Barry Childress in the early 1990s for the Psion Series 3 family of palmtop computers. The format was created for Childress's Reader3 application, a text file viewer that needed to fit large books into the Psion's extremely limited storage — typically 128 KB to 2 MB of available memory. TCR uses a dictionary-based compression scheme derived from the earlier ZVR format by Ian Giddings, replacing repeated byte sequences with single-byte tokens that reference a header dictionary. This straightforward approach achieves compression ratios of roughly 40-60% on typical English prose while requiring minimal CPU resources for decompression. The Psion Series 3 ran on a 3.84 MHz NEC V30 processor with no floating-point unit, so TCR's low computational overhead was essential for smooth page-by-page reading. A key advantage is remarkable storage efficiency for its simplicity — users could carry dozens of novels on removable SSD cards that held only a few hundred kilobytes. The format found a dedicated user community among Psion enthusiasts who built libraries of compressed literature for portable reading years before smartphones existed. Though the Psion platform faded from the market in the early 2000s, TCR files can still be opened and converted by modern ebook tools, and the format stands as an early example of purpose-built mobile reading technology from the pre-smartphone era.

Frequently Asked Questions

Why convert YUV to TCR?

Converting YUV to TCR lets you turn raw video frame data into viewable images for inspection or sharing — TCR is widely recognized and easy to share.

How do I open TCR files?

Open TCR files with Calibre, Psion organizer devices. Most operating systems handle TCR natively or with built-in viewers.

What quality can I expect from TCR output?

Quality depends on the source data, but TCR format provides compressed text for handheld devices for excellent results.

Can I use this converter on any operating system?

The tool is browser-based and works on Windows, macOS, Linux, ChromeOS, and mobile platforms — no OS-specific software needed.

What platforms support this conversion?

Any device with a web browser can run this conversion. Desktop, laptop, tablet, or phone — all supported equally.

Can I convert multiple YUV files at once?

Batch conversion is supported — upload several YUV files and each will be independently converted to TCR format.
