OBJ (OBJ) - Wavefront OBJ - universal 3D geometry format supporting vertices, normals, and texture coordinates. Best for universal 3d exchange between modeling software.
ABC (ABC) - Alembic - ILM open framework for baking and caching animated 3D scenes. Ideal for animation caching, film vfx pipeline, large scene interchange.

Yes, converting OBJ to ABC uses lossy compression, which reduces file size by discarding some visual data. Set quality to 85-95% for a good balance of quality and file size.
ABC files are typically 50-80% smaller than OBJ files because ABC uses efficient lossy compression. The exact reduction depends on quality settings.
Wavefront OBJ is a universal 3D geometry format that stores vertices, normals, texture coordinates, and face data in human-readable text. It is supported by virtually all 3D modeling applications.
ABC files are built around lossy compression. Designed for animation caching, film vfx pipeline, large scene interchange, they use the model/alembic MIME type and typically range from varies by content.
Reach for OBJ when your priority is universal 3d exchange between modeling software — its uncompromising quality ensures every detail is preserved.
Reach for ABC when your priority is animation caching, film vfx pipeline, large scene interchange — its efficient compression makes sharing fast and storage minimal.
