MuPDF demo with high-security redaction. The redaction toolbar includes an extra button labelled "SECURE SAVE".
After redacting elements, tap the button to save a new version of the document guaranteed to have no accidentally concealed information. This is achieved by saving images, and using OCR to reconstruct the text so that it is still selectable for annotating or further redaction.
Note: this is an alpha version and saving redactions can take a significant time.
