How SK1 to FB2 Conversion Works

SK1 file (SK1) stores data in the SK1 format. FB2 file (FB2) stores data in the FB2 format. This reformats the fixed-layout document into a reflowable ebook that adapts to screen size. Metadata such as creation date and embedded colour profiles is preserved where the target format supports it. The result is a standard FB2 file readable by any compatible application. 1converter handles SK1-to-FB2 conversion server-side: files are uploaded over HTTPS, processed on isolated cloud infrastructure, and the converted output is available for download for 24 hours before automatic deletion. No account is required for standard conversions.
