One PDF · metadata is read and shown before anything is changed
Honest note about redaction: black boxes cover the text on the page — they do not erase it from the file's internal data. A determined person could still extract the covered text. This is visual redaction for everyday sharing, not forensic removal. For legal-grade redaction, use a dedicated redaction tool.

How it works

1. Add your PDF

We show the metadata hidden inside it — author, dates, software.

2. Pick words to cover

Optional. Type names, numbers or phrases to black out, and preview.

3. Download clean

Metadata stripped, words covered. Nothing was uploaded.

Questions

What metadata is removed?

Title, author, subject, keywords, creator, producer, creation date and modification date — plus the embedded XMP metadata block where present.

Does blacking out text really remove it?

No — it covers the text with black boxes on the page. The original text may still exist inside the file's data. This is visual redaction, not forensic removal; for legal-grade redaction use a dedicated tool.

How do I choose what to black out?

Type the words or phrases (comma-separated). Every matching word on every page is covered, and you can preview the result before downloading.

Is my PDF uploaded?

No. Cleaning happens entirely in your browser; your file never leaves your device.
