SK file (SK) stores data in the SK format. Tagged Image File Format (TIFF) stores high-depth raster images with optional lossless LZW compression and supports multiple pages in a single file. This renders each page as a raster image, making the content viewable without a document reader. Each page is rendered at the specified DPI and saved as a separate image; text in the output is no longer selectable. The result is a standard TIFF file readable by any compatible application. 1converter handles SK-to-TIFF 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.
