JPEG to TGA converter

JPEG is a standard digital image format that uses a type of data compression algorithm to reduce file size. This makes it ideal for web pages, email, and other online media. JPEG files are often identified by the .jpg or .jpeg file extensions. The JPEG format allows for images with millions of colors, though their resolution is usually somewhat lower than other image file types.

The JPEG standard can be adjusted to various levels, allowing the user to trade off image quality for better compression. As such, JPEG can be used in a variety of ways - from low quality display images to high-resolution photographs. JPEG also includes metadata support in the form of markers and comments that allow for photo capture data, descriptions and other information to be embedded in the image.

TGA is a raster graphics file format developed by Truevision, Inc. It is primarily used for gaming purpose. It is a popular format for storing high-dynamic range content and intermediary frames for video production. TGA files come in uncompressed and compressed form and can be 8-bit or 16-bit. It can also contain 24-bit or 32-bit RGB color values.

A TGA file is composed of one or more Image Descriptors (ID), which contain information about the format and size of the image, as well as some other useful information such as bits per pixel, palette colors, etc. The TGA file format also supports various compression techniques such as RLE and ZIP compression.
