What is AI PDF Redactor and how does it work?

AI PDF Redactor is a free online tool from HuntPDF. Let AI find names, emails, phone numbers, IDs and card numbers in your PDF and black them out automatically. 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 AI PDF Redactor 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 AI PDF Redactor, then download the result. You can rename it before you save it.

Is my file secure when I use AI PDF Redactor?

Yes. The file you send to AI PDF Redactor 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 AI PDF Redactor has run?

No. Your upload is deleted the moment AI PDF Redactor 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. AI PDF Redactor 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 AI PDF Redactor on mobile?

Yes. AI PDF Redactor 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 AI PDF Redactor?

Yes. The file AI PDF Redactor 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 AI PDF Redactor?

No. There is nothing to download, install or sign up for — AI PDF Redactor 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 AI PDF Redactor take?

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

Is AI PDF Redactor free to use?

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

What does AI Redact PDF do?

It scans the text of your PDF for the type of detail you choose, then blacks out every match and gives you a new PDF to download.

What can AI Redact PDF find?

Names, email addresses, phone numbers, ID numbers, card numbers, IBANs, account numbers and postal addresses, depending on the option you pick.

What if it misses something?

Take the result into Redact PDF with 'Continue with this file' and cover the remaining parts by hand, or search a word and redact every copy of it.

Does it work on scanned documents?

It needs a PDF with selectable text. Run OCR PDF on the scan first, then redact the OCR'd copy.

Can I choose which kind of detail to hide?

Yes. Choose Personal info, Financial or Contact details. Run it again with a different option if you need more than one.

Should I still check the redacted PDF?

Yes. Read it through before sharing, especially unusual identifiers like staff numbers that may not look like personal data.

AI Redact PDF finds personal details in a PDF, such as names, email addresses, phone numbers, ID numbers and bank details, and blacks them out for you. It helps when a document is too long to check line by line.

How to use AI Redact PDF

Add the PDF by dropping it on the page or choosing it from Google Drive, Dropbox or OneDrive. Pick what to hide: Personal info (names, emails, phones, IDs), Financial (card numbers, IBANs, account numbers) or Contact details (emails, phones, addresses). Press Find & redact. The result tells you how many places were blacked out. Download the file, rename it, or send it on WhatsApp.

When AI Redact PDF helps

An HR officer shares a disciplinary file with an outside adviser and needs employee phone numbers hidden. A landlord sends a tenant's reference pack to a letting agent without the bank details. A researcher publishes interview transcripts with the participants' emails removed.

Check the result before you send it

Always read through the redacted PDF. If the tool reports that nothing sensitive was found, or it missed something specific to your document, such as a case reference, open Redact PDF and draw boxes over those parts by hand. The PDF needs real text, so run OCR PDF on a scan first.
