HEIC output can introduce lossy compression. Keep a master file for repeated editing.
Camera raw conversion requires decoding, demosaicing, white balance, tone mapping, and encoder choices.
Converting 3FR to HEIC decodes the source image and writes a HEIC output. Use this route when HEIC is a better fit for compatibility, file size, editing, or delivery.
HEIC is usually lossy in phone workflows. Converting to JPG is another lossy export, so choose quality carefully.
Convert HEIC to JPG for broad compatibility or to PNG when lossless decoded output or transparency workflows matter.
Strong in Apple workflows; cross-platform support varies.
