BatchMate — a single file. Keep it anywhere, copy it to a USB stick,
use it on a machine with no internet. It will still work in ten years because there is no
server to switch off.
Your images are read with the browser's own file reader and drawn on a canvas in memory.
There is no upload, no account, no telemetry, and no network request of any kind.
