About formats

SCT (Scitex Continuous Tone) is a high-end raster image format developed by Scitex Corporation for their prepress and color reproduction systems, with the HandShake format specification dating to 1988. Scitex, an Israeli company founded in 1968, was a pioneer in electronic prepress — their systems were used by major publishers, packaging companies, and advertising agencies to perform color separation, retouching, and page composition for high-quality print production. SCT files store images in CMYK color mode at 8 bits per channel (32 bits per pixel), with the color channels arranged in a band-interleaved-by-line format optimized for the scanline-based processing of Scitex's proprietary hardware. The format uses no compression, prioritizing direct access and processing speed over file size on the dedicated workstations where these files were used. SCT images were typically very large — high-resolution drum scans of transparencies and prints at resolutions of 300 dpi or higher for print-ready output. One advantage is print production heritage: SCT files represent some of the highest-quality digital prepress work of their era, scanned and color-corrected by expert operators on hardware that cost hundreds of thousands of dollars, making them valuable primary sources for reprinting and archival of commercial print work from the 1980s and 1990s. Adobe Photoshop has long supported SCT files for import, and the format can also be read by ImageMagick, XnView, and other tools with prepress format support.

PCT (also known as PICT) is a metafile graphics format originally developed by Apple Computer and introduced alongside the original Macintosh in January 1984. PCT files can contain both vector drawing commands and raster bitmap data, encoded as a sequence of QuickDraw drawing operations — the same graphics primitives used by the Macintosh operating system for all on-screen rendering. The format evolved through two major versions: PICT 1, which recorded basic QuickDraw operations (lines, rectangles, ovals, text, 1-bit bitmaps) in a compact format suitable for the original Macintosh's limited memory, and PICT 2, introduced with Color QuickDraw in 1987, which extended the format to support 24-bit color, multiple color spaces, and embedded JPEG-compressed data. PCT files begin with a 512-byte header (originally used for resource fork information), followed by the picture size, bounding rectangle, and a sequence of opcodes that define the drawing operations. During the Macintosh's commercial ascendancy, PICT was the universal graphics interchange format on Mac OS — the system clipboard used PICT for all graphical copy/paste operations, and most Mac applications could import and export the format. One advantage is the hybrid vector/raster nature: PCT files from the QuickDraw era preserve both scalable drawing commands and pixel data in a single format, enabling resolution-independent output for the vector portions. PICT's historical significance as the native Mac graphics format throughout the classic Mac OS era (1984-2001) provides another dimension. PCT files remain readable by Preview on macOS, ImageMagick, XnView, LibreOffice, and GIMP.

Frequently Asked Questions

Why convert SCT to PCT?

SCT is a specialized prepress format from Scitex with almost no support outside print production. PCT makes the image universally accessible.

What programs open PCT files?

PCT files can be opened in macOS Preview (older versions), XnView, IrfanView, and legacy Mac applications.

How long does SCT to PCT conversion take?

Most conversions finish within seconds. Processing time depends on your data size and server load, but results are typically ready almost instantly.

Does SCT to PCT conversion cost anything?

Basic conversions are completely free. If you need higher volume or larger data support, Convertio offers affordable premium options.

Is SCT to PCT conversion lossless?

The pixel data from your SCT source is mapped faithfully to PCT. Whether the result is lossless depends on the PCT format's compression method.

Can I convert multiple SCT data at once?

Yes — Convertio supports batch uploads. Queue several SCT inputs and convert them all to PCT in a single session to save time.
