How do I convert a 3FR file to DJVU?

Upload your Hasselblad 3FR file, select DJVU as the output format, optionally adjust the IW44 compression quality and DPI, then click 'Convert'. Our tool demosaics the raw sensor data and encodes it into a DJVU document. Download the result instantly.

Why should I convert 3FR to DJVU?

3FR files are large raw sensor captures from Hasselblad cameras, while DJVU is a highly compressed document format. Converting to DJVU reduces file size drastically via wavelet compression, making it easier to archive, share, or embed in digital libraries while retaining sufficient image quality for document use.

What happens to EXIF metadata and color depth when converting 3FR to DJVU?

The conversion demosaics the raw Bayer data and encodes the result using DJVU's IW44 wavelet codec. EXIF metadata (camera, lens, exposure) is preserved and embedded in the DJVU file. Color depth is typically reduced from 16-bit to 8-bit per channel due to DJVU's format limitations; DPI settings are retained for accurate printing or display.
