CoverUP is a free software designed to provide a secure and straightforward method for redacting PDF files
Users can import PDF documents into CoverUP, which are then converted into images. This conversion process ensures that the text cannot be copied from the document or indexed without OCR, enhancing the security of your information. In addition, invisible layers within the PDF are not converted, providing an extra layer of security against accidental leaks.
CoverUP also supports the import of PNG and JPG files. This is useful if you want to edit screenshots or images of documents taken with a mobile phone.
Given that image-based PDFs can become quite large, CoverUP offers two PDF export modes: A high-quality mode that maintains the visual fidelity of the document, and a compressed mode that reduces file size at the expense of some visual quality.
Whether you’re dealing with a single page or an entire document, CoverUP provides a flexible and easy solution for your PDF redaction needs no matter if you want to black out text, white out text or censor passages of your text.
