Workers AI - New conversion options for Markdown Conversion

You can now customize how the Markdown Conversion service processes different file types by passing a conversionOptions object.

Available options:

• Images: Set the language for AI-generated image descriptions
• HTML: Use CSS selectors to extract specific content, or provide a hostname to resolve relative links
• PDF: Exclude metadata from the output

Use the env.AI binding:

await env.AI.toMarkdown(
	{ name: "page.html", blob: new Blob([html]) },
	{
		conversionOptions: {
			html: { cssSelector: "article.content" },
			image: { descriptionLanguage: "es" },
		},
	},
);

await env.AI.toMarkdown(
	{ name: "page.html", blob: new Blob([html]) },
	{
		conversionOptions: {
			html: { cssSelector: "article.content" },
			image: { descriptionLanguage: "es" },
		},
	},
);

Or call the REST API:

curl https://api.cloudflare.com/client/v4/accounts/{ACCOUNT_ID}/ai/tomarkdown \
  -H 'Authorization: Bearer {API_TOKEN}' \
  -F 'files=@index.html' \
  -F 'conversionOptions={"html": {"cssSelector": "article.content"}}'
