Encoder: loads on first conversion. OneFreePlace prefers a pinned libavif WebAssembly codec for professional controls and falls back to native AVIF encoding only when the browser truly supports it. The codec download is not an image upload.

Safety caps: 100 files, 250 MB/file, 750 MB source batch, 100 MP/output. Smart Target uses bounded re-encodes and never silently distorts aspect ratio.
