GIF at a glance

Convert to GIF when you need a universally recognizable lightweight animation or a simple indexed-color image for broad web and messaging compatibility.

It is useful for short loops, reactions, and legacy-friendly image sharing.

SLN at a glance

SLN

Convert to SLN when preparing prompts, voicemail assets, on-hold audio, or other sound files for Asterisk-style telephony systems that expect raw signed-linear input.

It is the right target when PBX compatibility and predictable call-audio handling matter more than metadata or ordinary media-player support.
