Mindstorms Ready

Your SVG artwork converts directly to the format LEGO Mindstorms bricks display — custom graphics for robotics projects and competitions.

Clean Small Graphics

SVG vector precision produces sharp monochrome images even at Mindstorms display resolutions — cleaner results than downscaling photos.

No LEGO Software

Generate RGF files without installing LEGO Mindstorms desktop software — convert online and transfer the file to your brick.

About formats

SVG (Scalable Vector Graphics) is an XML-based vector image format developed by the World Wide Web Consortium (W3C), with the 1.0 specification published as a Recommendation on September 4, 2001. Unlike binary vector formats, SVG describes shapes, paths, text, gradients, filters, and animations in human-readable XML markup that can be authored in a text editor, processed by scripting languages, and styled with CSS. The format supports both vector elements (lines, curves, polygons defined by mathematical coordinates) and embedded raster images, along with interactivity through JavaScript event handling and declarative animations via SMIL or CSS transitions. SVG is natively rendered by all modern web browsers without plugins, making it the standard format for resolution-independent graphics on the web — from icons and logos to interactive data visualizations and animated illustrations. A major advantage is infinite scalability: SVG graphics remain perfectly sharp on any display, from low-DPI monitors to ultra-high-resolution Retina screens, because rendering is computed from geometry rather than pixels. The text-based nature provides another core strength — SVG content is indexable by search engines, accessible to screen readers, and trivially manipulable via the DOM using standard web technologies. The active W3C specification continues to evolve with modern web platform capabilities, maintaining SVG's position as the essential vector format for responsive web design.

RGF (Robot Graphics Format) is a simple monochrome bitmap image format used by LEGO Mindstorms EV3 programmable robotics kits, introduced with the EV3 system on September 1, 2013. RGF files store 1-bit (black and white) images designed for display on the EV3 Intelligent Brick's 178x128 pixel monochrome LCD screen. The format uses a minimal structure: a header containing the image width and height as binary values, followed by the pixel data where each bit represents one pixel (1 for black, 0 for white), packed eight per byte in row-major order. RGF images are used as custom display graphics in EV3 programs — students and hobbyists create them for robot status displays, user interfaces, splash screens, and animation frames shown on the brick's screen during program execution. The images are typically designed using LEGO's EV3 software (which includes a built-in image editor) or converted from other formats using community tools. RGF fits within LEGO's broader educational robotics platform, where the Mindstorms system teaches programming, engineering, and computational thinking to students worldwide. One advantage is the format's role in educational technology: RGF provides a simple, concrete example of how digital images are represented as binary data — a concept that students working with Mindstorms can directly observe by examining the file contents and seeing the corresponding image on the brick's screen. The format's simplicity makes it accessible for young programmers learning about file formats and binary data. RGF files can be created and converted using ImageMagick, the EV3 development environment, and community tools like ev3dev.

Frequently Asked Questions

Why convert SVG to RGF?

RGF is the image format for LEGO Mindstorms brick displays — converting SVG lets you show custom graphics on NXT and EV3 LCD screens.

What uses RGF files?

LEGO Mindstorms NXT and EV3 programmable bricks display RGF images on their built-in LCD screens during program execution.

What resolution is the Mindstorms screen?

The NXT screen is 100x64 pixels and the EV3 is 178x128 pixels — both monochrome. Your SVG is rasterized to fit these small displays.

Is RGF monochrome?

Yes — Mindstorms displays are monochrome, so RGF stores black-and-white pixel data matching the physical screen capabilities.

Is SVG to RGF conversion free?

Standard conversions are free on Convertio. Premium plans offer batch processing for creating multiple display graphics.
