ARW to PPM
File Converter

ARW is a raw image file format used by Sony digital cameras, capturing unprocessed data from the camera’s sensor. This format provides photographers with extensive flexibility in post-processing, allowing for adjustments to exposure, color balance, and other settings without loss of image quality, but it results in larger file sizes and requires specialized software to view and edit.

PPM stands for Portable Pixmap, and it is a simple image format that is part of the Netpbm package. The PPM format stores color images in a plain text or binary format, representing pixel values with three numbers for red, green, and blue color channels. PPM files are easy to read and understand, but they can be large in size as they do not employ any form of compression, resulting in each pixel being represented by full color intensity values.
