How is the JSON structure decided?

An AI model reads the extracted text and builds object and array names from the document's own headings, labels, and fields, instead of forcing it into one generic template.

No, only text content is converted. Images and complex layouts are not carried over.

Is there a page limit?

PDFs up to 1000 pages are accepted, and the first 120,000 characters of extracted text are sent to the AI model for conversion.

Is PDF to JSON free to use?

Yes, converting a PDF to JSON with AI is completely free with no signup.

How accurate is the JSON structure?

The AI model reads the document's layout and produces well-structured JSON, but always spot-check the result against the original PDF for anything critical.
