About formats

JPG is the most common file extension for images compressed with the JPEG standard, published by the Joint Photographic Experts Group as ISO/IEC 10918-1 in September 1992. The three-letter .jpg extension became dominant due to the 8.3 filename limitation of MS-DOS and early Windows, while .jpeg is the full-length variant — both extensions represent identical file contents and compression. JPEG applies lossy compression using the discrete cosine transform (DCT), dividing images into 8x8 pixel blocks, transforming them into frequency coefficients, quantizing to discard visually insignificant data, and entropy-coding the result. Users control the compression level: higher quality retains more detail at larger file sizes, while lower quality achieves dramatic size reduction with increasing visible artifacts in complex textures. The format supports 24-bit true color (16.7 million colors) and 8-bit grayscale, with Exif metadata embedding camera model, exposure settings, orientation, GPS location, and creation timestamp. One advantage is unmatched device compatibility — JPG is the native output format of virtually every digital camera and smartphone, and is displayed by every image viewer, browser, and operating system in existence. Efficient photographic compression is another strength: real-world photographs with smooth gradients and complex textures compress extremely well under DCT, typically achieving 10:1 reduction at high visual quality. JPG images power the vast majority of photographic content across the web, email, social media, and digital archives worldwide.

RGB is a raw (headerless) image format that stores pixel data as a flat sequence of red, green, and blue sample values with no container structure, compression, or metadata. Each pixel is represented by three consecutive bytes (in 8-bit mode) — one for red intensity, one for green, and one for blue — written in scanline order from the top-left corner of the image to the bottom-right. Because there is no header, the image dimensions and bit depth must be specified externally when reading the file. The format supports multiple bit depths: 8-bit (0-255 per channel), 16-bit (0-65535 per channel), and floating-point variants, with 8-bit being the most common. The RGB color model itself reflects how display hardware produces color — by mixing red, green, and blue light at varying intensities — and raw RGB files represent this model in its most direct digital form. With 8-bit channels, three bytes per pixel yield a 24-bit color palette capable of representing 16,777,216 distinct colors. One advantage is zero-overhead processing: without headers or compression to parse, raw RGB data can be memory-mapped, fed directly into GPU textures, or piped between processing stages with minimal latency — valuable in real-time imaging, scientific instrumentation, and computer vision pipelines where every millisecond matters. The format's universal simplicity provides another practical strength — any programming language can read or write raw pixel data with just basic file I/O, making it a reliable interchange format between custom software that may not share support for structured image containers. Raw RGB files are handled by ImageMagick, FFmpeg, and various scientific and graphics tools.

Frequently Asked Questions

Why convert JPG to RGB?

Raw RGB data is needed for custom image processing, embedded displays, and rendering pipelines that consume unformatted pixel arrays directly.

What opens RGB files?

Photoshop (File > Open As), GIMP with raw import, ImageMagick CLI tools, and custom scripts that parse raw pixel buffers can handle RGB data.

What does the RGB file contain?

Pure red-green-blue byte triplets for every pixel, in raster order — no headers, no compression, no metadata. Just raw color values.

How do I know the dimensions?

The RGB file does not store width/height metadata. You must know the original JPG dimensions to interpret the raw data correctly.

Is this conversion free?

Yes, standard JPG to RGB conversions are free on Convertio. Premium accounts add batch export and priority processing.
