256 colors max. Best for simple graphics.

Uncompressed bitmap. Very large files.

Vector trace. Best for logos and simple graphics. Not a pixel-perfect conversion.

Frequently Asked Questions

For most purposes yes. The decoded NEF is embedded at full pixel dimensions with 150 DPI page geometry, so a 45.7 MP D850 frame prints cleanly well beyond A4. Commercial print houses often want a TIFF with a defined colour profile instead, so confirm before sending.

Yes. Upload up to 50 NEF files and turn on the multi-page PDF option, and each photo becomes one page in upload order. Leave it off and each NEF becomes its own single-page PDF, returned together as a ZIP.

150 DPI by default, and you can request anything from 72 to 600. DPI here sets the physical page size the image is placed on rather than resampling the photograph — a higher value produces a smaller page holding the same pixels, which is what a print shop usually wants.

No. A PDF stores the rendered 8-bit image, not the sensor data, so the exposure latitude that makes a NEF worth keeping is gone. Archive the NEF itself and use PDF when someone needs a fixed layout they can open without photo software.
