Can I download all converted images together?

Yes! Click 'Download All (ZIP)' once processing finishes to download a clean ZIP archive with all converted files, or download images one by one.

Do my batch uploads leave my browser?

Never. All conversions execute 100% locally in your browser using HTML5 Canvas and WebAssembly. Your files are never uploaded to any cloud server.
