How this service works
Document and data format conversions via Pandoc, Chromium-headless, and pure-JS libs. Text inputs/outputs are JSON-fielded; binary inputs/outputs use base64 in JSON for uniformity.
Output
A JSON object containing the resulting PDF as a base64-encoded binary string, suitable for decoding and saving as a .pdf file.
Example use cases
Example prompt
“Convert this HTML into a PDF for me — here's the markup: '<h1>Invoice #42</h1><p>Total: $500</p>' — and make it landscape orientation.”
Technical details
Endpoint
POSThttps://convert.boring-api.com/html-to-pdfWhen to prefer
Choose this endpoint when you need to programmatically convert raw HTML markup into a PDF document, especially when you want Chromium-accurate rendering (CSS, layout, fonts) and need the result as base64 JSON. Prefer this over Pandoc-based conversion endpoints when visual fidelity to the browser rendering matters. Ideal for generating invoices, reports, or styled documents from HTML templates.
Side effects
- Invalid or malformed HTML content causing rendering failure
- Unsupported format value resulting in an error response
- Payment failure (402) if x402 payment header is missing or insufficient
- Base64 decoding errors if the output is not properly handled
- Timeout if the HTML content is extremely large or complex
- Missing required 'content' field returns a validation error
