What is Chat with PDF and how does it work?

Chat with PDF is a free online tool from HuntPDF. Ask questions about your PDF and get answers based on its content. You upload a file, the work happens on our servers, and you download the result. There is nothing to install and no account to create.

How do I use Chat with PDF online?

Upload your file using the box above — drag it in, browse for it, or bring it in from your cloud storage. A preview appears so you can check you've picked the right file. Run Chat with PDF, then download the result. You can rename it before you save it.

Is my file secure when I use Chat with PDF?

Yes. The file you send to Chat with PDF travels over an encrypted HTTPS connection and is processed automatically on our servers. It is never made public, never shared with anyone, and nobody reads it.

Does HuntPDF store my files after Chat with PDF has run?

No. Your upload is deleted the moment Chat with PDF finishes with it, and the file it produces is removed as soon as you have downloaded it, or when you upload another file, or when you close the page. Nothing is kept, and nothing is used to train anything.

Does it work on scanned PDFs?

Not on its own. The AI reads the text inside your PDF, and a scan is only a picture of a page with no text in it. Run the file through OCR PDF first to add a text layer, then come back.

Will the original quality and formatting be maintained?

Yes. Chat with PDF is built to leave your content exactly as it is — only the change you asked for is applied. Nothing else about the file is altered or re-compressed.

Can I use Chat with PDF on mobile?

Yes. Chat with PDF works in any modern browser on phones and tablets — iPhone, iPad or Android — with nothing to install. You can upload straight from your device or from your cloud storage.

Can I rename my file before downloading it from Chat with PDF?

Yes. The file Chat with PDF gives you back keeps the name of the file you uploaded by default. If you'd rather call it something else, edit the name in the field next to the download button before you save it.

Do I need to install any software to use Chat with PDF?

No. There is nothing to download, install or sign up for — Chat with PDF is used from your browser and does the work on our servers, so it behaves the same on Windows, macOS, Linux, Android and iOS.

How long does Chat with PDF take?

Most files are finished in a few seconds. A large or page-heavy file takes a little longer, because Chat with PDF runs on our servers rather than on your device — but you won't be waiting around. You can upload files up to 250MB.

Is Chat with PDF free to use?

Yes. Chat with PDF is free, with no signup, no watermark on the result and no daily limit for normal use.

What does Chat with PDF do?

It reads the text of the PDF you add and answers the questions you type about it, one reply per question, in a chat thread.

What kind of questions work best in Chat with PDF?

Specific ones: a date, a clause, a figure, a definition. 'What does clause 7 say about refunds?' gets a sharper answer than 'Tell me about this'.

Does it remember my earlier questions?

Each question is sent with the document on its own, so write every question in full rather than relying on the previous answer.

Why won't my scanned PDF work?

A scan is a picture of text. Run it through OCR PDF to add a text layer, then add the new file here.

What happens if the answer isn't in the document?

The reply tells you the document doesn't cover it, instead of filling the gap with outside information.

Can I switch documents mid-conversation?

Yes. Press Change file, add the new PDF, and start asking. The thread clears so answers don't get mixed up.

Chat with PDF lets you ask a long document a direct question and get a written answer, instead of scrolling through fifty pages to find one figure. It works on PDFs that contain real text, such as reports, policies, manuals and contracts.

How to use Chat with PDF

Add your PDF by dropping it on the page or choosing it from Google Drive, Dropbox or OneDrive. Type a question in the box, for example 'What is the notice period?' or 'What was total revenue in 2025?', and press Send. The answer appears in the thread above. Ask as many questions as you like, or press Change file to switch to another document.

When Chat with PDF saves time

A tenant checks what a lease says about pets before emailing the landlord. A new starter asks the staff handbook how much annual leave carries over. An analyst pulls one number out of a 90-page annual report before a call. In each case the question is specific and the document is long.

Getting clear answers

Answers come only from the text of your PDF. If the document doesn't cover something, the reply says so rather than guessing. Each question is answered on its own, so include the detail you care about ('the payment terms in section 4') rather than 'what about that?'. Scanned PDFs have no text to read yet: run OCR PDF first, then come back.
