Architectural FAQs: Bulk Execution

Why download files sequentially?
Most batch processors attempt to zip your final images together into a single file. This forces the browser to hold every processed image in RAM simultaneously, causing memory leaks and browser crashes for large batches. By triggering individual, sequential HTML5 downloads, we immediately flush the memory (Garbage Collection), allowing you to safely process hundreds of files locally.
Where do my downloaded files go?
Because this tool executes entirely offline, the resulting images are piped directly to your operating system's default Downloads folder. To keep things organized, your browser may prompt you to "Allow multiple file downloads" on your first use. We recommend creating a new folder on your desktop to easily gather the batch output.
