What the engine does with these images

Studio product shots are the case the classical engine is genuinely competitive on. A seamless backdrop means the colour-distance key produces a soft alpha directly, with no segmentation step to shrink thin structures, so straps, wires and handles survive intact.

How e-commerce teams run it

Catalogue teams process in batches at ingest, not one image at a time, so throughput and a machine-readable confidence signal matter more than an editor. The batch endpoint applies quota per item and returns 207 with a per-item outcome, so a partial batch is reported as one.

Delivering as PNG

PNG is the only output here that carries a real alpha channel, so it is the only one that preserves a soft edge rather than approximating it. That matters more than it sounds: the engine produces alpha as a smooth transfer over colour distance and never thresholds it to fully-on or fully-off, so an anti-aliased boundary, a strand of hair or the taper of a shadow arrives as genuine partial transparency. Flatten that to a binary mask and the edge acquires the stair-stepped look that makes a cutout read as a cutout. PNG is also lossless, so the file you receive is the file the engine produced — no recompression is quietly re-drawing the boundary you are about to composite.
