Redact PDFs, on your device
True redaction: text is burned out of the page, not just covered. Nothing uploaded, nothing tracked.
Drop a PDF to redact
Draw black boxes over sensitive info. Text is removed, not just covered.
How Locdone does this
No servers. No uploads. Just your browser's own abilities.
Drop a PDF
Locdone renders each page in your browser. You stay in control -- the file never leaves this tab.
Draw over what to hide
Click and drag to cover sensitive info. Add as many redactions as you need across any page.
Save a flattened PDF
Locdone rasterizes redacted pages with the black areas burned in. The text underneath is gone from the file, not just covered.
Questions
Is my PDF secure? Does it upload anywhere?
Your PDF never leaves your device. Verify by closing your internet connection, then drop a PDF and apply redactions. Open DevTools (F12) Network tab and watch it stay empty during processing.
What's the difference between true redaction and drawing a black box?
Most "redact" tools layer a black rectangle on top of text -- but the original text is still in the file and can be extracted by selecting, copying, or running it through a PDF parser. Locdone rasterizes each redacted page into an image with those pixels simply gone. There is no underlying text to recover.
Is this HIPAA or court-filing compliant?
Locdone handles the visible content properly: redacted text is gone from the page. For thorough compliance, also strip the PDF's metadata (author, software, creation date) using our Strip PDF Metadata tool -- metadata can identify who created the document even after redaction.
Will pages without redactions stay text-searchable?
Yes. Locdone copies untouched pages verbatim as vector content. Only pages with redactions are flattened to images.
Can I redact on mobile?
Touch drawing works in most mobile browsers. Precision is easier on a trackpad or mouse for small areas of text.
