Redactar (tachar) información sensible de un PDF

A common mistake when trying to hide sensitive information in a PDF is simply drawing a black rectangle over the text with a basic image or PDF editor. The problem: the original text is still there underneath — anyone can select and copy it, or remove the rectangle with an editor. Real data leaks have happened because of exactly this mistake.

Real redaction requires removing the underlying text, not just covering it visually. This tool searches for exact matches of the terms you enter across the whole document and converts those pages into images before blacking them out — so the text is genuinely gone, not hidden behind a box.

It's the right tool before sharing a contract with an account number that shouldn't be shown, a form with a third party's personal data, or any document where you need to hide specific information in a verifiable way.

The cost of that guarantee: the entire document loses its selectable text, not just the redacted part, because every page is converted to an image equally. It's the necessary trade-off for redaction you can actually trust.
