Cleanor Labs
These sections explain the job in plain language and set expectations for what the tool should do well.
To redact a PDF, add one file and draw redaction boxes over the content you need to hide, choosing black, white, gray, or blue to match the page. Each box stays editable inside the browser, so you can move, resize, or remove it before you finish. When you export, the tool produces a flattened copy where the boxes are baked into the page.
The entire workflow runs locally in your browser, so the source PDF never leaves your device. That matters for redaction, because the documents you are hiding details in are usually the most sensitive ones you handle.
Use it to cover addresses, account numbers, names, signatures, and any private references before a PDF is emailed, uploaded, or shared with people outside your team.
Unlike a simple drawing overlay, this tool exports a flattened PDF where each page is rebuilt after the color boxes are applied. That means the covered content is no longer present underneath the box in the exported file, so it cannot be selected or copied out of the share-safe copy.
The tradeoff is that flattening can remove searchable text, fillable forms, and annotations, leaving a more image-like PDF. Keep the original document if you still need it to be editable, and treat the redacted export as the version you share.
Short answers for the questions people usually have before trying a utility like this.
Yes. The PDF Redaction Editor is free to use with no account and no upload queue. You redact and export the file locally.
No. The redaction workflow runs entirely in your browser, so the source PDF stays on your device during processing.
No. The export is a flattened PDF where each page is rebuilt after the boxes are applied, so the covered content stays hidden in the exported file.
Yes. Each box stays editable inside the browser, so you can move, resize, or delete it before exporting the final redacted PDF.
Not necessarily. Flattening can remove searchable text, forms, and annotations, so keep the original if you still need an editable version.
