True Pixel Flattening
Unlike weak PDF viewers that merely paint black boxes over live text, FileKit flattens the raster surface so data is permanently destroyed.
Metadata Purging
Automatically scrubs author tags, timestamps, creation history, hidden XML XMP streams, and interactive form fields.
100% Offline & Private
All rendering and scrubbing runs in your local browser engine. No files or byte chunks are ever sent to an external server.
