Frequently Asked Questions
How do I redact a PDF for free?
Drop your PDF into the upload area, use your mouse to draw rectangles over the information you want to hide, then click “Download Redacted PDF.” No software, no account, no cost.
Is the redaction permanent?
Yes. The tool draws filled black rectangles directly into the PDF file. The covered content is visually hidden, though the underlying text may still be present in the document code. For maximum security, consider converting the page to an image after redaction.
Can I undo a redaction?
Before downloading, you can use the “Undo Last” button to remove the most recent rectangle on the current page, or “Clear Page” to reset all marks on that page. After downloading, the redactions are baked into the file.
Does this tool work on large PDFs?
Yes. The free PDF redact tool supports files up to 30 MB and multiple pages. Performance depends on your device, but typical documents load quickly.
Are my files uploaded to a server?
No. This is a browser‑based PDF redactor — every action happens locally on your computer. Your PDFs are never sent anywhere, giving you total privacy.
Can I redact multiple pages at once?
You can mark different rectangles on each page individually. There is no batch redaction across all pages, but you can quickly switch between pages to mark them all before downloading.
