DJVU is a document format: it stores data in the DJVU format. PSD is a image format that preserves non-destructive editing layers, masks, adjustment layers, and smart objects in a proprietary Adobe format. 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. Converting between these two formats is common when the source application does not support PSD natively or when the target platform only accepts PSD. 1converter processes this conversion server-side using open-source tools. Files are transferred over HTTPS, converted on secure cloud servers, and automatically deleted after 24 hours.
