Registration alone is not a production-quality guarantee. |\n| Browser execution | Use the visible action or interactive controls. |\n| Browser processing | Browser; see tool notes for network behavior. |\n| HTTP API | Not callable through HTTP. |\n| Browser-agent interface | run_current_tool |\n\n### Implementation notes\n\nRuns in your browser. Animated inputs produce a single still image. Supported decoding depends on your browser.\n\n### Inputs and settings\n\nNo free-text input is required. Use the file inputs and/or settings below.\n\nAccepted browser files: `image/*,.svg,.avif`. Choose one file.\n\n| Setting | Meaning | Control type | Default | Constraints |\n| --- | --- | --- | --- | --- |\n| `width` | Width (px) | number | \"\" | min=1 max=16384 step=1 |\n| `height` | Height (px) | number | \"\" | min=1 max=16384 step=1 |\n| `lock` | Keep aspect ratio | checkbox | true |  |\n\n### Browser-agent workflow\n\n1. Open the human page in a browser that supports WebMCP.\n2. Discover the interface exposed by that page; use its actual schema.\n3. Select files on the page first when the tool requires files.\n4. Call `run_current_tool` with valid input and settings.\n5. Inspect the returned result or error and the displayed output. Retrieve files from the displayed download links.\n\nCalls do not automatically copy or download results. Browser permissions still apply. Interface availability alone is not proof of successful execution.\n\n### Planning specification\n\nPixels/percent, aspect lock, fit/crop modes, no unintended upscaling, batch dimensions.\n\nThis describes intended requirements. Use the implementation notes, interface schema and observed output to determine current support.\n\n### Complete machine-readable capability record\n\n```json\n{\n  \"id\": \"resize-image\",\n  \"category\": \"image-tools\",\n  \"built\": true,\n  \"requirements\": \"Pixels/percent, aspect lock, fit/crop modes, no unintended upscaling, batch dimensions.\",\n  \"implementation\": {\n    \"fields\": [\n      {\n        \"key\": \"width\",\n        \"label\": \"Width (px)\",\n        \"value\": \"\",\n        \"type\": \"number\",\n        \"min\": 1,\n        \"max\": 16384,\n        \"step\": 1\n      },\n      {\n        \"key\": \"height\",\n        \"label\": \"Height (px)\",\n        \"value\": \"\",\n        \"type\": \"number\",\n        \"min\": 1,\n        \"max\": 16384,\n        \"step\": 1\n      },\n      {\n        \"key\": \"lock\",\n        \"label\": \"Keep aspect ratio\",\n        \"value\": true,\n        \"type\": \"checkbox\"\n      }\n    ],\n    \"files\": true,\n    \"accept\": \"image/*,.svg,.avif\",\n    \"input\": false,\n    \"note\": \"Runs in your browser.
