FAQ
Does it work on scanned PDFs?
The tool searches the text stored in the PDF. Scanned pages are images: run OCR, save the result as a searchable PDF, then open that file to search it.
Is my file uploaded?
No. Searching and redacting both happen in your browser, and the file is not uploaded to a server.
