AVIF (AV1 Image File Format) is a new image format based on the AV1 video codec. It provides outstanding image quality and compression efficiency.
Portable GrayMap (PGM) is a simple grayscale image format, storing each pixel as a grayscale value in ASCII or binary form.
Reach for AVIF when your priority is modern web, next-generation web applications — its efficient compression makes sharing fast and storage minimal.
Reach for PGM when your priority is grayscale image processing, scientific data — its uncompromising quality ensures every detail is preserved.

No, converting AVIF to PGM does not cause additional quality loss — PGM uses lossless compression. However, any artifacts already present in the original AVIF file will persist in the PGM output.
PGM files are typically 2-5x larger than equivalent AVIF files because PGM preserves all pixel data. This is expected and necessary for lossless quality.
Yes, PGM supports transparency. Alpha channel information from AVIF is preserved during conversion.
