HEIF Sequence, burst photo format from Apple cameras — stored as image/heif-sequence — uses lossy encoding to handle ios burst photos, live photos, motion photos. Typical file sizes: varies by content.
Portable PixMap (PPM) is a simple color image format that stores RGB pixel data in ASCII or binary representation.
Reach for HEIFS when your priority is ios burst photos, live photos, motion photos — its efficient compression makes sharing fast and storage minimal.
Reach for PPM when your priority is simple color image processing, academic use — its uncompromising quality ensures every detail is preserved.

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