Free. Runs in your browser. Nothing is uploaded.
Rinse a PDF before you hand it to an AI.
A PDF can carry text you never see: white-on-white instructions, notes parked off the page, scripts, attachments. RinsePDF turns every page into a plain picture, then gives you a clean PDF or plain text made only from what is visibly on the page.
The same page, two readers
What you see
What an AI reads
Hidden text is invisible to you and fully readable to a model. After rinsing, both readers get the same page.
How it works
Every page becomes a picture
Your browser draws each page to pixels, like a screenshot. Only what is visible makes it into the picture.
The original is set aside
Hidden text layers, scripts, attachments, form data, links and metadata are never copied over.
You get a clean copy
A new PDF built only from those pictures, or plain text read from them by OCR that runs on your device.
What rinsing removes
Anything a PDF reader would not paint on the page is gone from the copy.
- Invisible text. White-on-white, zero-size, behind images, or placed outside the page edge.
- Scripts and actions. JavaScript and open or launch actions do not exist in a picture.
- Embedded files. Attachments tucked inside the PDF are not carried over.
- Links and form fields. No clickable targets, no hidden field values.
- Metadata. Author, software, dates and edit history are dropped.
- Layers and comments. Switched-off layers and hidden notes stay behind.
- Photo location data. GPS position and camera details stored inside photos are dropped.
What it cannot do
Know the limits before you rely on it.
- Visible text stays. If an instruction is printed where you can read it, it is kept. Very small or very faint text that is technically visible can also survive.
- It is not antivirus. Rinsing makes a safe copy. It does not scan or repair the original, so do not open a suspicious original in other software.
- The clean PDF is pictures. You cannot select or search its text, screen readers cannot read it, and the file is often larger.
- OCR makes mistakes. Handwriting, tables and small print are the usual trouble. Check important numbers against the page.
For students, scans and view-only files
Have a reading you can only view on screen, a photo of a handout, or a scanned chapter? Photograph, paste or capture the pages and RinsePDF merges them into one clean PDF or text you can study with an AI tutor. Use it only with material you are allowed to copy.
Why you can trust it
No upload, and you can check
The work happens in your browser's memory. Open the network tab in your browser's developer tools while you rinse a file: you will see it is never sent.
Open-source engines
Pages are drawn with Mozilla's pdf.js, rebuilt with pdf-lib, and read with Tesseract. All three are served from this site, not from a third party.
Plain about limits
This is one layer of protection. It removes what you cannot see. It does not judge what you can.
Works offline
After your first visit the tools are saved in your browser. Switch off your connection and it still works, which is the simplest proof that nothing is sent.
Questions
Is my PDF uploaded anywhere?
No. The page loads the tools into your browser and the file is processed in memory on your device. It is never sent to our server or anyone else's.
What is hidden text, and why does it matter for AI?
A PDF stores text separately from how the page looks. Someone can add text that is white, tiny, or off the page. You do not see it, but an AI tool that extracts the text reads it like any other sentence and may follow it. This is called prompt injection.
Clean PDF or plain text: which one should I choose?
Choose the clean PDF to keep the layout, for AI tools that read page images. Choose plain text for the smallest file and full transparency: you can read exactly what the AI will receive.
Can I use photos or screenshots instead of a PDF?
Yes. Drop images, paste a screenshot, take a photo on your phone, or capture pages from your screen. You can mix them with PDFs and get one clean PDF or text file back. Photos also lose their location data.
Does it remove viruses or ransomware from a PDF?
The clean copy contains only pictures, so scripts, launch actions and attachments from the original cannot be in it. That is not the same as antivirus. The original file is unchanged, and RinsePDF does not detect malware.
Why can't I select text in the clean PDF?
Because each page is now an image. That is what guarantees nothing hidden came along. If you need selectable text, use the plain text option.
Is it really free?
Yes. There are no accounts, limits or watermarks. The site may show ads to cover its costs. Ads load separately and never receive your files.
