Photo Compositor Rev 2 — Streaming Batch Merge

Photos (PNG) 0

Drop PNG photos here or click to browse Transparent foreground subjects. Held as references — not decoded until processing.

Backgrounds (JPG) 0

Drop JPG backgrounds here or click to browse Any size — stretched to the output canvas by default. Reused across batches.

Pair & queue 0

Each selected photo pairs with each selected background (20 photos × 1 background = 20 outputs). Alternate instead cycles the selected backgrounds across the photos in order (photo 1 → bkg 1, photo 2 → bkg 2, photo 3 → bkg 1, …). Queued pairings are self-contained, so after queuing you can Clear photo list, load the next batch, and queue again — the queue keeps everything. Removing a source here does not remove pairings already queued.

ZIP mode holds every rendered file in memory to build the archive, so it isn't recommended for very large batches (hundreds+). For big runs, use Individual — it saves each file as it renders and frees the memory immediately.

Output is sRGB. Duplicate-safe naming is automatic: if two photos share a name, the background name (then a counter) is appended so nothing overwrites.

Drop shadow Off

Casts the photo's own silhouette as a soft shadow behind it — defaults to a gentle, heavily-blurred shadow leaning slightly back, as if the light is almost directly overhead. Off by default. All values are remembered for next time. Offset and blur are stored as a percentage of the canvas, so what you see in the preview is exactly what the full-size output produces.
