NiFi Ingest 23.2

# Redaction

Redacts images.

When the input is in one of the following formats, the redacted output is in the same format:

- PNG
- TIFF
- BMP
- GIF (the processor can process only the first frame of an animated GIF)
- JPEG
- PBM, PGM, PPM
- WebP

- PDF

  IMPORTANT: To perform redaction on a PDF file, the processor converts the PDF into images. This means that although the output is in PDF format, any content besides text and images (for example comments or form entries) is lost, and everything is rendered as pixels (text can no longer be searched or highlighted).

For other formats, the redacted output is produced in either PNG or TIFF format (TIFF is used when the input contains multiple pages).

In the FlowFile, the redacted image replaces the original.
