How to Convert Files

Work with PAL colour palette files alongside common image formats in your browser. All processing happens locally on your device.

What a PAL file holds

PAL denotes a colour palette: an ordered list of colours, typically stored as red, green, and blue triplets, without any pixel image data. It defines the set of colours that an indexed image or a piece of graphics hardware may use.

Palettes appear throughout computing, from the fixed colour tables of retro game consoles and DOS-era graphics to the swatch files used by paint and design programs. A PAL file is not a picture in itself; it is the reference table that an indexed image points into, which is why it is small and contains only colour definitions.

Strengths and limits

Separating the palette from the image is useful: a single palette can be shared across many images to keep a consistent look, swapped to recolour a whole scene at once, or edited without touching pixel data. The files are tiny because they store only colours.

The trade-off is that a PAL is meaningless on its own, since it carries no image. There is also no single universal PAL layout: several programs use the .pal extension for their own slightly different structures, so a palette from one tool may need conversion before another can read it.

History of PAL Format

The PAL format emerged in the early days of computer graphics, primarily in the 1980s. Various developers created it to address the limitation of displaying a limited number of colors on screens, especially in systems with constrained memory. By defining a palette, developers could optimize memory usage while allowing for a broader range of colors in images. This approach was particularly useful for early graphics hardware and software, which often struggled with color representation.

As graphics technology advanced, the PAL format became widely adopted in various applications, from video games to desktop publishing. It facilitated the creation of swatch libraries and indexed images, allowing designers to maintain color consistency across projects. Over time, tools for creating and editing PAL files emerged, leading to some standardization. However, variations in palette layouts persisted, reflecting the diverse needs of different software and hardware environments.

Using PAL Effectively

Choose PAL when working with indexed graphics or when color consistency is essential across multiple images. It is particularly beneficial in scenarios where memory constraints exist, such as in older hardware or embedded systems. PAL is also useful for applications that require quick color changes across a series of images, as updating the palette automatically updates the colors in all associated graphics without needing to modify pixel data.

Be aware of compatibility issues when converting to or from PAL. Some graphics software may not fully support custom palette layouts, leading to color discrepancies. When exporting images, ensure the target format can handle indexed color modes. Additionally, keep track of the palette size; exceeding the limits may result in incorrect color representation. For best results, use dedicated tools for creating and managing PAL files to avoid potential pitfalls during conversion.

Working with PAL files

You will meet PAL files when working with indexed graphics, sprite art, or applications that let you save and load colour swatches. The palette is applied to an image that references it by index.

Because the extension is used by several incompatible layouts, check which program produced a PAL file before importing it. To bake a palette into a viewable image, apply it to the indexed data and export the result as PNG or GIF, both of which store their palette internally.
