About formats

DST (Tajima) is a machine embroidery file format created by Tajima Industries, one of the world's leading manufacturers of commercial embroidery equipment. The format encodes stitch data as a sequence of relative coordinate movements, with each stitch record containing a horizontal offset, vertical offset, and a command flag indicating the stitch type — normal stitch, jump (move without stitching), color change, or stop. DST files use a compact binary encoding where each stitch occupies three bytes, making the format efficient for storing complex multi-color designs with tens of thousands of stitches. The coordinate system uses 0.1 mm increments with a maximum single-stitch length of 12.1 mm in any direction. DST has become the de facto standard in the commercial embroidery industry — virtually every embroidery machine from any manufacturer can read DST files, making it the most widely supported embroidery format in existence. One advantage is universal machine compatibility: a DST file will run reliably on Tajima, Barudan, SWF, Brother, and Melco machines alike, eliminating format conversion concerns. The minimal file structure is another strength — files are compact, load instantly even on older machine controllers with limited memory, and their simplicity makes them resistant to corruption during transfer. While DST lacks embedded metadata like thread color names and design previews, this limitation is offset by the format's unmatched portability across the global embroidery industry.

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.

Frequently Asked Questions

Why convert DST to RGB?

SGI RGB format is used in professional graphics and 3D pipelines. Converting DST renders embroidery for those workflows.

What programs open RGB files?

Adobe Photoshop, GIMP, XnView, and SGI workstation applications handle RGB image files natively.

Does RGB preserve full color?

Yes — RGB stores red, green, and blue channels, rendering the DST thread palette as a full-color image.

Is RGB a compressed format?

SGI RGB supports optional run-length encoding. Uncompressed mode keeps data lossless at the cost of larger files.

Is DST to RGB free on Convertio?

Completely free — upload your DST file and download the RGB result without any charges or signup.

Does this work on all operating systems?

Convertio runs in any browser. Windows, macOS, Linux, and mobile users all access the same converter.
