Why convert TGA to HEIF?

HEIF isn't automatically 'better' than TGA in every case – but for Apple devices — efficient storage, it's the clearer choice. This conversion processes your files entirely in your browser using WebAssembly – no upload, no server, no privacy concerns. Perfect for sensitive or large batches. Once you see the size or compatibility difference, going back rarely makes sense.

JPEG compression introduces minor quality loss — set quality to 90%+ to minimize
