Registration alone is not a production-quality guarantee. |\n| Browser execution | Use the visible action or interactive controls. |\n| Browser processing | Server required |\n| HTTP API | /api/v1/tools/woff2-to-ttf/run |\n| Browser-agent interface | run_current_tool |\n\n### Implementation notes\n\nProcessed on our server with no external conversion service. Only TrueType-outline WOFF2 is supported. CFF-outline fonts require an OTF output and are rejected here.\n\n### Inputs and settings\n\nNo free-text input is required. Use the file inputs and/or settings below.\n\nAccepted browser files: `.woff2`. Choose one file.\n\nBrowser file-input limit: 20971520 bytes in total. HTTP limits can differ.\n\nNo additional settings are declared for this tool.\n\n### HTTP contract\n\nAPI calls process supplied data on the server. The website origin is `https://happytails.ai`. Server API hosting is not connected on the public website yet. Use your local server origin to test these requests.\n\n```http\nPOST https://happytails.ai/api/v1/tools/woff2-to-ttf/run\nContent-Type: application/json\n```\n\n[Detailed operation reference](https://happytails.ai/en/api/tools/woff2-to-ttf.md) · [Shared API guide](https://happytails.ai/en/api.md)\n\n#### Limits\n\n| Limit | Value |\n| --- | --- |\n| request_bytes | 31457280 |\n| input_characters | 1000000 |\n| files_bytes | 20971520 |\n| max_files | 1 |\n| timeout_seconds | 90 |\n\n#### Complete input schema\n\n```json\n{\n \"type\": \"object\",\n \"additionalProperties\": false,\n \"properties\": {\n \"input\": {\n \"type\": \"string\",\n \"maxLength\": 1000000,\n \"default\": \"\",\n \"description\": \"Plain text input.

Correct invalid input before retrying; retry server-busy responses with bounded backoff. Returned files contain Base64 data, not persistent download URLs. Decode and inspect the output before treating conversion as successful. See the shared API guide for the complete status and timeout rules.\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\nReject CFF-based fonts rather than relabeling them as TTF; preserve glyphs, mapping and metrics.\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\": \"woff2-to-ttf\",\n \"category\": \"font-tools\",\n \"built\": true,\n \"requirements\": \"Reject CFF-based fonts rather than relabeling them as TTF; preserve glyphs, mapping and metrics.\",\n \"implementation\": {\n \"fields\": [],\n \"files\": true,\n \"accept\": \".woff2\",\n \"multiple\": false,\n \"input\": false,\n \"processing\": \"Server required\",\n \"native\": true,\n \"expansion\": true,\n \"maxFileBytes\": 20971520,\n \"note\": \"Processed on our server with no external conversion service.
