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.

AVIF (AV1 Image File Format) is a modern image format derived from the AV1 video codec, developed by the Alliance for Open Media and specified in February 2019. The format leverages the intra-frame coding tools of AV1 — a royalty-free video codec backed by Google, Apple, Microsoft, Amazon, Netflix, and other major technology companies — to compress still images with substantially higher efficiency than JPEG, PNG, or even WebP. AVIF stores images in the HEIF (High Efficiency Image File Format) container, supporting both lossy and lossless compression, HDR (high dynamic range) with wide color gamuts up to 12-bit depth, alpha transparency, and animated sequences. At equivalent visual quality, AVIF files are typically 30-50% smaller than WebP and 50-70% smaller than JPEG, representing the largest compression improvement in mainstream image formats in over a decade. One advantage is exceptional compression efficiency — AVIF delivers visually indistinguishable images at dramatically lower file sizes, directly reducing bandwidth consumption and improving page load times for web content. The royalty-free licensing model provides another key strength: unlike HEIC/HEIF which relies on patent-encumbered HEVC, AVIF's AV1 foundation is free for anyone to implement without licensing fees. Browser support has reached broad adoption, with Chrome, Firefox, Safari, and Edge all rendering AVIF natively. The format is rapidly gaining adoption for web images where quality-to-size ratio is paramount.

Frequently Asked Questions

Why convert SCT to AVIF?

The Scitex CT format has extremely niche support. AVIF conversion frees the image data for everyday viewing and editing.

What programs open AVIF files?

AVIF files can be opened in Chrome, Firefox, Safari, Edge, and modern image editors with AVIF support.

Is batch SCT to AVIF conversion possible?

Yes, Convertio lets you upload multiple SCT inputs at once. All of them are converted to AVIF in parallel, speeding up your workflow.

Is SCT to AVIF conversion lossless?

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

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.
