Removes the content, not just the view

Redact a PDF

Drag a box over anything that has to go. The page is then rebuilt from pixels, so what was underneath is not covered up — it stops existing.

Why this one works differently

An ordinary annotation rectangle only covers the page visually. The words underneath can remain selectable or recoverable. Removing confidential content requires a redaction operation and a careful check of the saved result.

Marked pages are rebuilt as images, with the marked areas removed from those pixels. Those pages lose their searchable text layer and may increase the file size. Pages without marks are preserved. The tool checks that no text can be extracted from the rebuilt pages before offering a download. Review every page and any document metadata before sharing: information outside your marks is not automatically removed.

What Redact PDF does

Use Redact PDF to draw areas over private information and review every mark before saving. Marked pages are rebuilt so the covered content is removed rather than left beneath a movable black rectangle. Filozy performs the work in this tab; your document is not uploaded.

How to redact pdf in your browser

  1. Choose one PDFSelect one PDF from the dropzone. Filozy reads it locally and shows the relevant preview or controls before changing anything.
  2. Mark private contentDraw a box over every area that must be removed, including repeated headers and image-only occurrences. Review every mark before saving.
  3. Create and check the resultRun the tool, review the reported page count, size, or notes, then save the newly created file while keeping the original.

Limits worth knowing

  • This workflow stops on interactive forms rather than risk losing their fields. Use Flatten first and check every visible answer in that saved copy, then open the flattened PDF here. Keep the editable original; protected or XFA forms may need a compatible form application first.

Essential questions

Does Redact PDF upload my file?

No. The selected file is opened and processed by code running in this browser tab. Document bytes and filenames are not sent to Filozy.

Will this change my original file?

No. Browsers cannot silently overwrite the file you selected. Filozy creates a separate result for you to save or pass to another local tool.
