# Redact PDF Content

> Most redaction tools paint a black rectangle on top of the text. The original characters stay in the content stream and leak through Select All, copy-paste, or any PDF inspector. This one destroys the underlying text run and overlapping annotations — the bytes are gone. Search-and-redact marks every SSN or name across the document at once.

Category: PDF & Documents

## How it works

1. **Select PDF** — Drop the PDF that contains the sensitive content, or click to pick one
2. **Select areas to redact** — Draw rectangles over text or images you want to permanently remove
3. **Download** — Download your redacted PDF with content permanently removed

## FAQ

### Is the redacted content truly removed?

Yes. Redacted content is permanently destroyed, not just covered. It cannot be recovered from the output PDF.

### Can I search for text to redact?

Yes. You can search for specific words or phrases and redact all occurrences at once.

### Does this preserve bookmarks and form fields?

Yes. Bookmarks, form fields, and unrelated annotations stay. Redaction permanently removes the underlying text and any annotation that overlaps the redacted region.

## Tips

- **Bytes are removed, not covered** — Redactions destroy the underlying text run and any annotation overlapping the region. Copy-paste, text search, and PDF inspectors cannot recover the content.
- **Black-box overlays still leak** — Many redaction tools draw a filled rectangle on top of the text. The original characters remain in the content stream and surface via Select All or text extraction.
- **Search redacts every occurrence** — Search for a name, SSN, or phrase to mark all matches across the document at once instead of drawing rectangles page by page.

## Privacy — what we do not do

This tool runs entirely in the browser via WebAssembly. Your file never reaches a Loft Tools server. Specifically:

- **No upload.** The file bytes load into the browser tab's memory and process on your own CPU. Open DevTools → Network and observe zero outbound requests carrying file data while Redact PDF Content runs.
- **No AI training on your file.** Loft does not train models. We could not train on a file we cannot see.
- **No content scanning.** No virus, copyright, or content-moderation pass against your file. The bytes are not accessible to us.
- **No server-side log of file contents, filenames, or EXIF metadata.** Cloudflare edge captures URL and truncated IP for abuse defense (standard CDN behaviour). Cloudflare Web Analytics records anonymous page hits, no cookies, no PII. Nothing about your file content reaches any log.
- **No retention.** Close the tab and the file leaves browser memory. No backups exist on our side because no copy ever existed on our side.
- **No account.** No email, no signup, no auth, no telemetry tied to you.
- **Offline-capable after first visit** (PWA). Once you've loaded a tool, it caches; later sessions work without internet. For high-sensitivity files, run the tool once online to warm the cache, then disconnect before processing.

Compare with upload-based services: each transmits your file to a processing server. Even over HTTPS, each has logs, retention windows, and subpoena exposure. Loft has none of these because the server architecture does not include your file.
