Convert ART to RGB

Understanding ART and RGB file formats

ART is a proprietary image file format developed by America Online (AOL) for compressing graphics, primarily used in the early days of dial-up internet to speed up image loading. ART files are rarely used today and are not widely supported by modern software.

RGB is a raster image file format that stores uncompressed pixel data in the Red, Green, and Blue color channels. RGB files are often used in graphics applications and scientific imaging due to their simplicity and high quality.

Why convert ART to RGB?

Converting ART files to RGB format allows you to preserve image quality and make the files accessible in modern image editing and viewing software. RGB files are compatible with a wide range of applications, making them ideal for further editing or archiving.

How to convert ART to RGB

Since ART is a legacy format, direct conversion tools are limited. The best approach is to use a two-step process:

1. First, convert the ART file to a more common format like BMP or PNG using a legacy image viewer or converter that supports ART files.
2. Then, convert the resulting file to RGB format using an image editor or specialized converter.

Recommended software for ART to RGB conversion

• XnView Classic: This free image viewer supports ART files and can export them to BMP or PNG. Use File → Save As to choose your desired format.
• IrfanView: Another popular image viewer that may support ART files with the right plugins. Use File → Save As to export to BMP or PNG.
• ImageMagick: Once you have a BMP or PNG, use ImageMagick to convert to RGB with a command like convert input.bmp rgb:output.rgb.

Step-by-step conversion process

1. Open your ART file in XnView Classic or IrfanView.
2. Export the file to BMP or PNG using File → Save As.
3. Use ImageMagick or another image converter to convert the BMP/PNG to RGB format.

Tips and considerations

• ART files may lose some quality during conversion due to their heavy compression.
• RGB files are uncompressed and can be large in size.
• Always keep a backup of your original ART files before converting.
