Upload a NEF image and save it as PNM without installing desktop image software.
NEF is a format for original, raw graphic files created by Nikon technology. Accordingly, the developer of the format is also the specified company. The name of the format is an abbreviation for Nikon Electronic Format. At the same time, NEF format files received by Nikon cameras of different models can have a different structure, so compatibility is not guaranteed. Nikon's graphic editors are geared towards supporting specific camera models. When creating a file, the data comes directly from the matrix. NEF files are of good quality and contain metadata, and therefore take up a lot of space.
PNM is a raster image category format. This is a bitmap bitmap created in Portable Any Map format. As you know, this format was intended from the very beginning to process some types of portable monochrome black and white images (PBM), color images (PPM) and grayscale images with shades of gray (PGM). Allows the inclusion of raster graphics data in the .PBM, .PGM or .PPM format. Such formats can provide an intermediate representation of data during the conversion of raster graphic files by different platforms. Separate applications support these three formats directly because they are defined as the PNM format. Able to be stored using binary data or ASCII text.
PNM is the common format for the Netpbm package. It contains intermediate files that are used when it comes to converting several open source programs called Portable Bitmap. The PPM format was developed by J. Poskanzer. This is the easiest format for storing graphics. PNM files store one image. They do not apply compression. To view and process a bitmap image in PNM format, you can use programs such as GIMP, ImageMagick, Newera Graphics Converter Pro, XnViewMP. The same programs are able to convert images of this format.
