Resize JPEG

POST /api/image-resize-jpeg

Resize a JPEG to specified dimensions. Pass only one dimension to preserve aspect ratio. Configurable quality on re-encode.

Resizes a JPEG to the requested `width` × `height`. Pass one of them as `0` (or omit) to derive that dimension from the source aspect ratio. Output is JPEG with configurable quality (default 80). For a different output format see `image-resize` (multi-format) or the format-specific resize tools.
