What Filee does for NEF → JPG
NEF files are too large and too unusual to send as they are. As JPG they become small, universally viewable photos; use JPG 70 % or a half-size preset for messaging apps. Nikon's NRW files from Coolpix cameras work the same way.
- Built in: works right after installing Filee, with nothing else to download.
- Engine: ImageMagick.
- Metadata (EXIF, XMP, colour profile) is kept by default and can be removed for privacy.
- Batch: one file or hundreds, converted in parallel; a failure never stops the rest.
- Private: files are converted on your PC and never uploaded, even without internet.
- Saved next to the original, or in a folder and with a file name pattern you choose.
NEF can also become
- PNG
- WEBP
- AVIF
- TIFF
- BMP
- GIF
- ICO
- PSD
- TGA
- PPM
- JPEG XL
- JPEG 2000
- ICNS
About NEF and JPG
JPG
JPEG image
JPEG is the most widely used photo format. Its lossy compression keeps files small, but every save at lower quality discards some detail, and it has no transparency.
