Create a masked copy of a PDF

Starting parameters

Use an unsigned, unencrypted PDF without XFA. Inspect every page, including rotated pages; the synthetic two-page document contains invented text and links.

Processing steps

1. Load the PDF, visit each page and add opaque regions wherever sensitive content appears.
2. Adjust or remove regions and compare the original with the preview. Mask all repeated occurrences, not just the first visible one.
3. Export a new PDF. Every page is rasterized and the original text, forms, links, annotations and attachments are omitted.

Check the result

Open the download in another reader. Verify page count, orientation, mask edges and remaining visible information; search should not expose the original text.

Limits and losses

Searchable text, vector detail, accessibility and interactive features are lost, and size can grow. No automatic sensitive-content discovery or legal redaction certification is provided.

Local processing

Files and outputs stay in this browser; originals are not overwritten. Samples contain invented data. Download results before clearing or leaving. OCR downloads its recognition model, not your document.
