CRW

The CRW file format is a Canon proprietary RAW image format used by Canon digital cameras. It retains unprocessed image data, offering superior image quality and flexibility during post-processing. Ideal for photographers, CRW files facilitate detailed edits while preserving original quality, making them a preferred choice for professional and amateur photographers alike.

PGM

The Portable Gray Map (PGM) format is a simple, portable image file that represents grayscale images. It is part of the Netpbm format family, suitable for easy manipulation and conversion. PGM files store pixel intensity values in plain text or binary, ensuring broad compatibility across various platforms and applications. Ideal for graphic designers and developers looking for a straightforward approach to grayscale image processing.
