FTS to ELECTRONIC Publication conversion is the process of transforming FTS image-based files into the EPUB ebook format by extracting images and embedded text, reflowing or embedding content, and packaging it into an EPUB container for e-readers. This conversion adapts the original FTS image assets and metadata into EPUB-compliant resources (HTML, CSS, image assets, and manifest) so they can be read on apps and devices that support ELECTRONIC Publication files.

The FTS file format typically uses a specialized MIME type associated with its source software, often without universal standards. EPUB files use the MIME type application/epub+zip and contain XHTML, CSS, and XML components for formatting and metadata. EPUB supports advanced codecs for multimedia integration, making it suitable for interactive publications.
The ELECTRONIC Publication (.EPUB) format is commonly used for image. Understanding its characteristics can be helpful when converting to or from other formats like FTS.

FTS files are often proprietary and limited in compatibility, primarily used in niche applications. In contrast, EPUB is a universal electronic publication format designed for accessibility and adaptability across numerous devices. EPUB’s reflowable content and broad support make it a preferred choice over FTS for digital reading.
Keep individual images under 5–10 MB when possible to ensure responsive performance on e-readers; aim for total EPUB size under 100–200 MB for general distribution.
To preserve visual fidelity, choose lossless export or high-quality JPEG/WebP and use fixed-layout EPUB for image-heavy content like comics or illustrated books.
For many files, convert in batches but limit batch sizes to avoid memory/timeouts — recommended 10–20 FTS files per batch depending on server resources.
Note format limitation: FTS is primarily an image/scan container and may not include structured text or semantic markup, so OCR might be required to produce searchable, selectable EPUB text.
