About formats

MAP is an internal raster image format used by ImageMagick, the open-source image processing suite first released by John Cristy at DuPont on August 1, 1990. MAP files store indexed-color (color-mapped) images in ImageMagick's native representation: a color palette (the map) followed by pixel data where each pixel is an index into that palette rather than a direct RGB value. The format provides a compact representation for images with a limited number of distinct colors — each pixel requires only enough bits to index the palette (typically 8 bits for up to 256 colors), compared to the 24 or 32 bits per pixel required by full-color formats. MAP serves primarily as an intermediate format within ImageMagick's processing pipeline, useful when performing operations that benefit from or require palettized representation: color quantization (reducing an image to a specific number of colors), palette manipulation, GIF preparation, and indexed-color analysis. The format is invoked through ImageMagick's standard I/O syntax and can be piped between processing stages without disk overhead. One advantage is direct access to ImageMagick's color quantization and palette management capabilities: MAP format output makes the palette structure explicit and manipulable, enabling workflows where specific palette operations (reordering, remapping, merging) need to be performed between processing steps. The format's integration into the ImageMagick processing ecosystem is another practical strength — any of ImageMagick's extensive image manipulation operations can consume or produce MAP format data, making it a natural intermediate for color-reduction pipelines that ultimately target GIF, PNG with palette, or other indexed-color formats.
Initial release: 1990
SK is the native file format of Skencil (originally named Sketch), a free vector graphics editor for Linux created by Bernhard Herzog, with the first public release on October 31, 1998. Skencil holds historical significance as one of the earliest full-featured vector drawing applications written almost entirely in Python, with only performance-critical rendering components implemented in C. The SK file format uses a text-based, Python-like syntax to describe document structure — pages, layers, groups, and individual graphic objects are represented as nested statements with parameters specifying coordinates, colors, line styles, and transformations. The format supports Bezier curves, rectangles, ellipses, text objects with font specifications, imported raster images, gradient and pattern fills, and hierarchical grouping with affine transforms. One advantage is human readability — SK files can be opened in any text editor, making it possible to inspect, modify, or generate artwork programmatically using simple scripts. The Python-native structure also provides a benefit for automation: since Skencil itself is a Python application, the file format integrates naturally with scripting workflows for batch processing and procedural graphic generation. While Skencil's development slowed after the mid-2000s, its SK format became the foundation for the sK1 project, which extended the format and continued active open-source vector graphics development. SK files remain convertible through sK1, UniConvertor, and other open-source tools.

Frequently Asked Questions

Why convert MAP to SK?

MAP requires niche software to open. Converting to SK lets you share and view your color maps on virtually any platform.

What programs open SK?

Open SK in Illustrator, Inkscape, CorelDRAW, or Affinity Designer. For viewing, many image viewers handle this format.

Is the conversion instant?

Near-instant for typical images — the cloud-based processing handles MAP to SK conversion quickly. Very large data may take a moment.

Is the output quality comparable?

The conversion extracts the best possible quality from your MAP data. The SK output reflects the format's capabilities accurately.

Does this work on mobile devices?

Yes — the converter runs in any web browser, so it works on phones, tablets, laptops, and desktops regardless of operating system.

Can I batch convert MAP to SK?

Yes — Convertio supports batch uploads. Add multiple MAP images and convert them all to SK at once to speed up your workflow.
