About formats

PSD (Photoshop Document) is the native file format of Adobe Photoshop, the industry-standard raster image editor first released on February 19, 1990. PSD files preserve the complete editing state of a Photoshop project: all layers (raster, text, adjustment, shape, and smart object layers) with their positions, blending modes, opacity, and layer effects; layer masks and vector masks; alpha channels; spot color channels; paths; guides; slices; and the full undo history. The format supports images up to 30,000 x 30,000 pixels (PSB, the large document format, extends this to 300,000 x 300,000) in color modes including RGB, CMYK, Lab, Grayscale, Indexed, Duotone, and Multichannel, at 1, 8, 16, or 32 bits per channel. PSD files use a combination of RLE compression for individual layer data and store composite (flattened) preview images for quick display by applications that cannot parse the full layer structure. The format has become a de facto standard for professional creative workflows far beyond Photoshop itself — photographers, graphic designers, web developers, and video post-production artists exchange PSD files as the working format that preserves creative flexibility. One advantage is the non-destructive editing model: PSD preserves every layer, mask, adjustment, and effect as independently editable elements, allowing creative decisions to be revised at any point without starting over. The format's role as the interchange standard for the creative industry provides another core strength — PSD files can be opened by Adobe Illustrator, InDesign, After Effects, Premiere Pro, as well as Affinity Photo, GIMP, Sketch, Figma, and Photopea, making it the lingua franca of visual 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 PSD to RGF?

RGF is useful when you need your Photoshop design in a specific format for specialized tools, legacy systems, or particular workflows.

What opens RGF files?

LEGO Mindstorms EV3 software and brick display handle the RGF format for viewing and processing.

Does conversion flatten PSD layers?

Yes — RGF is a flat format. All Photoshop layers merge into a single image during the conversion process.

Is the output quality good?

Your PSD artwork is rendered at high quality before encoding into the RGF format for maximum fidelity.

Is PSD to RGF conversion free?

Standard conversions are free on Convertio. Premium plans offer batch processing and faster speeds.
