How batch mode works
Images run one after another so your device's memory stays steady; the tray under the tool shows each one as waiting, working or done. Click any finished image to check it, touch it up with the brush, or download it on its own. Background, format and crop settings apply to the whole batch; brush edits belong to each image.
How long a batch takes
With WebGPU on a computer, each photo takes a few seconds, so 50 photos take a few minutes. On the CPU engine each photo takes roughly 10 to 30 seconds, so large batches are best done on a computer with WebGPU. You can keep working in other tabs; the batch pauses if the browser puts the tab to sleep and resumes when you come back.
