What is PDF Redaction?
PDF redaction is the deliberate removal of sensitive information from a document before it is shared,
archived, printed, or disclosed. A proper redaction workflow does more than cover text with a dark box.
It ensures the final exported document no longer carries the original visible content on the affected area.
ToolsMatic handles the full review flow in the browser. You can inspect each page, draw exact marks, search
for predictable patterns such as email addresses or phone numbers, and export a clean redacted copy without
sending the original file to a server.
How to Redact a PDF on ToolsMatic
Upload your PDF: Drop the document onto the upload zone or browse for it manually.
Mark every sensitive area: Draw boxes or search for matches across all pages.
Review the marks: Use the sidebar to jump between redactions and refine placement.
Apply and export: Confirm the action, download the redacted PDF, and keep the JSON report if needed.
Redaction Tools Included
Draw tool
Draw freeform rectangles anywhere on the page. Marks can be moved, resized, selected from the sidebar, or nudged
with the keyboard for more precise placement.
Search and redact
Search with plain text, regex, or fast presets for email addresses, phone numbers, SSNs, and payment card patterns.
Review the matches before turning them into redaction marks.
Preview styles
Choose solid black, a custom color, blur, or pixelation. Each selected style is rendered into the exported PDF, so
the visible result matches the preview you approve.
