Traditional Cloud Risks vs On-Device RAM Execution
Client confidentiality breach when using public cloud editors
Uploading confidential discovery files to cloud servers violates attorney-client privilege and risks enterprise NDA breaches.
PDFBlack operates exclusively in local browser RAM; outbound file upload network requests are mathematically zero.
Court rejection of trial binders due to pagination flaws
Courts frequently reject electronic filings that lack persistent sequential numbering across disparate evidentiary exhibits.
Integrated Bates stamping engine supporting case prefixes, zero-padding, and cross-document continuous pagination.
Defective visual masking (black rectangles that fail to redact)
Drawing black boxes over text leaves underlying digital characters intact, allowing opposing counsel to copy sensitive data.
Forensic binary sanitization that physically removes and destroys targeted characters and image streams.
