Common questions

Is Chat with PDF free?

Chat with PDF is a Pro feature ($5/month flat, free trial) — the everyday tools (merge, split, rotate, organize, watermark, page numbers, image to PDF) stay free with no sign-up, no watermark and no daily limit.

How do I chat with a pdf?

Open Chat with PDF, drop your file, set the options, and download the result in a few seconds — processed securely, no queue and no ads.

Is my PDF uploaded?

No. The text is extracted from the PDF in your own browser and only that text is sent to be processed; the file itself stays on your device.

Does my PDF get uploaded?

Your file stays on your device; only the extracted text is sent to our AI provider (Anthropic) to answer your question. The text is extracted in your own browser.

Can it make things up?

Answers are built from your document's own text and come with the passages they were drawn from, so you can check any answer against the source rather than taking it on trust.
