Frequently Asked Questions (FAQ)
Q: Does this tool upload my confidential documents to any server?
A: No. The PDF rendering, blackout drawing and document reconstruction pipeline operates entirely within your browser memory. Your files never leave your computer or phone.
Q: How does the blackout export protect sensitive information?
A: Redacted content is flattened into the rendered page, removing the original selectable text layer from the exported PDF. Blackout boxes are burned into image pixels rather than floating vector shapes.
Q: What is the difference between blackout and blur?
A: Blackout replaces pixel data completely with solid black boxes, which is recommended for sensitive text. Blur or mosaic is merely visual concealment and may carry risk of computer-assisted reconstruction.
Q: Does the file size change after export?
A: Because pages are rasterized to eliminate hidden text objects, the exported PDF contains high-resolution page images. File size depends on page count and resolution.
