JP2 at a glance

JP2

Convert to JP2 when image preservation, high bit depth, or institutional-quality digitization matter more than ordinary browser ubiquity.

It is a strong target for archival masters and specialist imaging repositories.

AC3 at a glance

AC3

Convert to AC3 when the output is intended for surround-capable consumer playback, especially DVD, broadcast, legacy streaming hardware, or home-theater distribution.

It is a strong target for 5.1-compatible delivery where broad device support matters more than lossless fidelity.

For mastering or archival preservation, lossless formats are usually better.
