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.
Multiple-Image Network Graphics (MNG) is an animation format based on PNG compression, supporting complex frame-based and sprite animations.
Reach for HEIFS when your priority is ios burst photos, live photos, motion photos — its efficient compression makes sharing fast and storage minimal.

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