PDF eraser (redact sensitive info)

Drag a box over sensitive information like ID numbers, account numbers, and amounts to erase it. It doesn't just cover the text — it deletes the underlying data so it can't be recovered by copying or searching.

What is Redact Personal Info from PDF?

A feature that safely erases sensitive information such as resident registration numbers or account numbers from a PDF. It does more than paint a black box over them — it removes the underlying text itself so it cannot be revealed by copying or searching.

How it works

1 Upload the PDF you want to redact.
2 Drag to mark the areas to erase.
3 Download the PDF with those areas removed.

Frequently Asked Questions

If I copy over the black box, will the text show? ⌄

The text itself is deleted, so nothing is revealed even if you copy or search.

Do scanned-image PDFs work? ⌄

The specified areas are masked in the output. For text PDFs, the underlying text is removed as well.
