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 BitMap (PBM) is a simple monochrome image format that stores each pixel as either black or white in an ASCII text 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 PBM when your priority is simple image processing, scientific visualization — its uncompromising quality ensures every detail is preserved.

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