FAQ

Are my images uploaded anywhere?

No. The images are decoded, normalized, and exported in your browser. They are not uploaded to a server.

Why does export take a while?

The browser creates normalized frames and then encodes an MP4 locally with WebAssembly. Keep the tab open until it finishes.

Does the export add a watermark?

No. The generated MP4 is watermark-free.

How are frames ordered?

Use the Sort by Name button for numbered sequences, or reorder frames manually before export.
