Currently this tool processes one image at a time. For batch resizing, you can process each image sequentially — the settings are preserved between uploads.
There's no fixed limit. Processing happens in your browser, so it depends on your device's RAM and CPU. Images up to 20MB or 8000×8000px work well on most devices.
