How do I convert DJVU to ORF using LetsConvert?

Upload your .djvu file to the converter, choose 'ORF' as the output format, and set the DPI to 300 or 600 in the advanced options. For multi-page documents, select 'Convert All Pages' to output each page as a separate .orf file. Click 'Convert' and download your ORF files; a ZIP archive is generated for multiple pages.

Why should I convert DJVU to ORF instead of storing as PDF or JPEG?

DJVU is a compressed document format for scans, while ORF is a raw image format from Olympus cameras. Converting to ORF gives you 12-bit depth for professional editing, lets you adjust white balance without data loss, and integrates with GPU-accelerated photo editors. It also avoids the DjVu browser plugin dependency, making your scans viewable in standard raw pipelines.

How are DJVU's layers and color profiles handled when converting to ORF?

Each DjVu page's raster background is flattened onto the foreground; since ORF has no layer stack, meshes are merged at the original resolution. ICC profiles are embedded in the output ORF, and bitonal pages are converted to 16-bit grayscale. Embedded OCR text becomes EXIF metadata, while DPI and print dimensions are preserved up to 600 DPI.
