file· File resultOpen tool

Quick start

Call this tool from your code in three languages.

cURL

# 1) Upload each file first → returns { filePath }
curl -X POST 'https://api.elysiatools.com/upload/avif-to-optimized-avif' \
  -F 'file=@/path/to/imageFile.ext'

# 2) Call the tool with the returned filePath values
curl -X POST 'https://api.elysiatools.com/en/api/tools/avif-to-optimized-avif' \
  -F 'imageFile=/path/to/file.ext' \
  -F 'quality=80' \
  -F 'effort=4' \
  -F 'chromaSubsampling=4:2:0' \
  -F 'lossless=false' \
  -F 'targetSize=Enter target file size in KB...' \
  -F 'maxFileSize=Enter maximum file size in KB...' \
  -F 'denoiseLevel=0' \
  -F 'sharpness=1' \
  -F 'clearMetadata=true' \
  -F 'removeExif=false' \
  -F 'keepColorProfile=false' \
  -F 'preserveTransparency=true'

API reference

Send a POST request with your inputs as JSON. File parameters require a separate upload first.

Endpoint

HTTP

POST https://api.elysiatools.com/en/api/tools/avif-to-optimized-avif

Parameters

Name	Type	Required	Description
imageFile	fileupload required	Yes	—
quality	range	No	Output quality (1-100, higher is better but larger)
effort	range	No	Compression effort (0=fast, 9=slowest but best compression)
chromaSubsampling	select	No	Chroma subsampling for color compression
lossless	checkbox	No	Use lossless compression for perfect quality
targetSize	text	No	Target file size for optimization (KB)
maxFileSize	text	No	Maximum allowed file size (KB)
denoiseLevel	range	No	Noise reduction level (0=none, 10=maximum)
sharpness	range	No	Image sharpening level (0=none, 10=maximum)
clearMetadata	checkbox	No	Remove all metadata for maximum compression
removeExif	checkbox	No	Remove EXIF metadata while keeping color profile
keepColorProfile	checkbox	No	Preserve original color profile (may increase file size)
preserveTransparency	checkbox	No	Keep alpha channel for transparency

File-type parameters must be uploaded first via POST /upload/avif-to-optimized-avif, then the returned filePath is passed to the corresponding file field.

MCP integration

Add this tool to your Model Context Protocol server so AI agents can list and call it.

Server configuration

Add this block to your MCP client configuration:

mcp.json

{
  "mcpServers": {
    "elysiatools-avif-to-optimized-avif": {
      "name": "avif-to-optimized-avif",
      "description": "Optimize AVIF images for better compression and performance while maintaining visual quality",
      "baseUrl": "https://api.elysiatools.com/mcp/sse?toolId=avif-to-optimized-avif",
      "command": "",
      "args": [],
      "env": {},
      "isActive": true,
      "type": "sse"
    }
  }
}

List available tools

After connecting to the SSE endpoint, list the exposed tools:

tools/list

{
  "jsonrpc": "2.0",
  "id": 1,
  "method": "tools/list"
}

Call this tool

Invoke the tool by its id, passing arguments built from its parameters:

tools/call

{
  "jsonrpc": "2.0",
  "id": 2,
  "method": "tools/call",
  "params": {
    "name": "avif-to-optimized-avif",
    "arguments": {
  "imageFile": "https://example.com/file.ext",
  "quality": 80,
  "effort": 4,
  "chromaSubsampling": "4:2:0",
  "lossless": false,
  "targetSize": "Enter target file size in KB...",
  "maxFileSize": "Enter maximum file size in KB...",
  "denoiseLevel": 0,
  "sharpness": 1,
  "clearMetadata": true,
  "removeExif": false,
  "keepColorProfile": false,
  "preserveTransparency": true
}
  }
}

Chain multiple tools in one session with a comma-separated toolId list, e.g. /mcp/sse?toolId=png-to-webp,jpg-to-webp,gif-to-webp (max 20).

File parameters accept a public file URL only (https://…). Local paths, data: URIs, and Base64 strings are not supported.
