FAQ

Are redactions legally sound?+

Yes. Blackline AI flattens the page and bakes the black bars into the image. Unlike many PDF tools, text underneath cannot be copied, searched or recovered — critical for journalists.

Are my documents stored anywhere?+

No. OCR, rendering and export happen in your browser. Close the tab and the files are gone.

Does it work with scans?+

Yes. Built-in OCR reads scanned pages, JPG/PNG photos and multi-page PDFs.
