SK file (SK) stores data in the SK format. WebP Image (WEBP) supports both lossy and lossless encoding with transparency and animation, typically 25-35% smaller than equivalent JPEG or PNG files. 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 WEBP file readable by any compatible application. 1converter handles SK-to-WEBP 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.
