CDT to SUN conversion is the process of transforming a drawing file in the CorelDraw Template (CDT) format into the SUN raster image format used by Sun Raster (SUN/RAST). This conversion extracts vector and embedded bitmap content from a CDT template and renders it into the SUN raster structure so the image can be opened by software that supports Sun Raster images.

CDT files typically use the MIME type application/x-cdt and contain vector-based drawing data specific to CAD tools. SUN files use application/x-sun format, designed to support efficient rendering and cross-platform compatibility. Both formats use specialized codecs to encode drawing elements but differ in structural design optimized for either editing or sharing purposes.
The SUN (.SUN) format is commonly used for drawing. Understanding its characteristics can be helpful when converting to or from other formats like CDT.
While specific technical details aren't available here, SUN files generally serve the purpose of storing drawing effectively within their domain.
Our Online CDT to SUN Converter provides a seamless way to convert your CDT drawing files into SUN format without hassle. Designed for professionals and hobbyists alike, this tool ensures high-quality, efficient transformation of files within seconds. No software downloads or technical knowledge required—just upload your CDT file and get your SUN output instantly.
CDT files are primarily associated with certain CAD software known for detailed drawing capabilities, while SUN files are favored for their portability and compatibility across multiple design platforms. While CDT focuses on native editing features, SUN files are optimized for sharing and viewing, making the conversion useful depending on your workflow needs.
Keep CDT source files under 200–500 MB for faster, more reliable web conversions; very large templates with many embedded images may require desktop tools.
To preserve visual quality, export at the original DPI or higher and choose 24-bit truecolor SUN output when color fidelity matters.
For batch conversions, group CDT files with similar page sizes/DPIs to avoid per-file resampling; use command-line or bulk-conversion tools when possible.
Limitations: SUN is a simple raster format, so complex vector features, editable text and effects from CDT will be rasterized and cannot be preserved as vectors.
