Redact PDF Online — Free & 100% Private
Redacting a PDF means permanently removing confidential text — names, account numbers, medical details — so it can never be recovered. AccuPDF lets you draw redaction boxes over any page and downloads a version where the hidden content is flattened out of the file entirely. Unlike other online tools, your document is never uploaded to a server — the whole process runs in your browser.
How to redact a PDF
- Drop your PDF into the tool — pages render instantly in your browser.
- Click and drag to draw a black box over any text or image you want to hide. Add as many boxes as you need across every page.
- Click Apply Redactions & Download. The pages are flattened to images with the redactions baked in, so the underlying text is permanently gone.
Is this real redaction?
Yes. Many “redaction” tools simply draw a black rectangle on top of the text, leaving the original words selectable underneath — a well-known cause of data leaks. AccuPDF flattens each redacted page so the hidden content is removed from the file, not just covered. Always review the downloaded file before sharing.
Why AccuPDF for redaction?
For law firms, healthcare, finance and HR, uploading a sensitive document to a third-party server is itself the risk. AccuPDF redacts entirely on your device — no uploads, no sign-up, no watermarks. Your files stay with you from start to finish.
