01

Can this edit text already drawn by the PDF?

It can detect many selectable text lines, remove the covered source text, and place a matching editable text box. Complex or image-only text may not be available.

  • Direct editing of detected text lines
02

Can I edit a digitally signed or encrypted PDF?

No. Signed and password-protected files are refused. Preserve the protected original and work from an authorized unsigned, unencrypted copy.

  • Text, images, signatures, drawing, shapes, highlights and notes
03

Does redaction guarantee forensic erasure?

No. The editor attempts to remove covered text and reports when it cannot, but unusual PDF content may remain. Inspect the output and use a specialist workflow for high-risk disclosure.

  • Page reorder, rotate, duplicate, delete, merge and extract controls
