About formats

RGB is a raw (headerless) image format that stores pixel data as a flat sequence of red, green, and blue sample values with no container structure, compression, or metadata. Each pixel is represented by three consecutive bytes (in 8-bit mode) — one for red intensity, one for green, and one for blue — written in scanline order from the top-left corner of the image to the bottom-right. Because there is no header, the image dimensions and bit depth must be specified externally when reading the file. The format supports multiple bit depths: 8-bit (0-255 per channel), 16-bit (0-65535 per channel), and floating-point variants, with 8-bit being the most common. The RGB color model itself reflects how display hardware produces color — by mixing red, green, and blue light at varying intensities — and raw RGB files represent this model in its most direct digital form. With 8-bit channels, three bytes per pixel yield a 24-bit color palette capable of representing 16,777,216 distinct colors. One advantage is zero-overhead processing: without headers or compression to parse, raw RGB data can be memory-mapped, fed directly into GPU textures, or piped between processing stages with minimal latency — valuable in real-time imaging, scientific instrumentation, and computer vision pipelines where every millisecond matters. The format's universal simplicity provides another practical strength — any programming language can read or write raw pixel data with just basic file I/O, making it a reliable interchange format between custom software that may not share support for structured image containers. Raw RGB files are handled by ImageMagick, FFmpeg, and various scientific and graphics tools.
Initial release: 1990
CUR is the cursor image format for Microsoft Windows), structurally nearly identical to the ICO (icon) format but with the addition of a hotspot coordinate that identifies the precise pixel position where mouse clicks register. Introduced with early Windows versions, CUR files use the same container structure as ICO: a directory header listing one or more image entries, each specifying dimensions and color depth, followed by the pixel data for each variant. Like ICO, a single CUR file can contain multiple images at different sizes and color depths, allowing Windows to select the most appropriate cursor image for the current display resolution and color settings. Image data within CUR files can be stored as BMP pixel arrays (for legacy compatibility) or as embedded PNG images (supported since Windows Vista) for alpha-blended cursors with smooth edges. The hotspot coordinate — the distinguishing feature separating CUR from ICO — is stored as an X,Y pair in the directory entry header, typically pointing to the tip of an arrow or the center of a crosshair. One advantage is multi-resolution packaging: a single CUR file provides appropriate cursor imagery across display densities from standard DPI to high-DPI screens. Native Windows integration is another strength — CUR files are loaded directly by the operating system for mouse cursor) display without any third-party software. CUR files are used by application developers and theme creators to customize the pointing experience across Windows environments.

Frequently Asked Questions

Why convert RGB to CUR?

RGB stores unstructured pixel values that most programs cannot interpret. Converting to CUR packages the data into a format anyone can open.

Can I use this converter on any operating system?

The tool is browser-based and works on Windows, macOS, Linux, ChromeOS, and mobile platforms — no OS-specific software needed.

How does Convertio protect my uploaded data?

Your RGB data is encrypted during transfer and deleted after processing. Converted CUR outputs are purged from servers within 24 hours.

Does this work on Mac and Linux?

Convertio is entirely browser-based, so it works on macOS, Linux, Windows, and even mobile platforms without any software installation.

Can I convert RGB to CUR for free?

Yes, Convertio offers free RGB to CUR conversion. For heavy usage or larger data, premium subscriptions provide additional capacity.

What makes CUR a good target format?

CUR offers cursor hotspot data, Windows UI element, ICO-based. It gives your raw RGB data a proper structure that any image viewer or editor can handle.
