PrivacyScanPDF Alternative: How PlainFile Compares
By the PlainFile team · Published September 16, 2026 · 5 min read
PrivacyScanPDF and PlainFile belong to the same family: browser-based PDF tools that process files locally instead of uploading them to a server. If that is the property you are after, both deliver it. The differences are in focus, price and how much you have to trust the maker. This page is an honest comparison — including the things PrivacyScanPDF does better. Facts are as of September 2026, from both products' public pages.
The one-minute version
| PlainFile | PrivacyScanPDF | |
|---|---|---|
| Approach | One tool, done properly: true PDF redaction | A broad suite of 60+ PDF and image utilities |
| Price | Free, unlimited, no account | Free trial, then a paid subscription (listed at $6.99/month) |
| Source code | Open source (AGPL-3.0) — auditable by anyone | Proprietary |
| Redaction depth | Content deletion + full document sanitization + automatic post-redaction verification | A redact tool among many; no documented verification step |
| File handling | 100% in-browser (WASM), works offline after first load | 100% in-browser (WASM) |
| Extras | None — redaction only | PII scanner, C2PA / Content Credentials checker, OCR, format conversion |
Where PrivacyScanPDF is the better choice
Credit where it is due. If you need a wide toolkit — merging, splitting, compressing, converting images, checking C2PA provenance signatures — a 60+ tool suite covers more ground than a single-purpose redactor. Their local PII scanner, which flags potential personal data before you share a file, is also a genuinely useful idea that PlainFile does not currently offer. If your workflow is "many different PDF chores, occasionally", take a look at them.
Where PlainFile is the better choice
If the task is specifically redaction — removing sensitive content so it cannot be recovered — the details matter more than the tool count:
- Verified, not assumed. After applying redactions, PlainFile automatically re-opens the output, extracts all text and searches for every redacted term. You get "Verified: 0 matches remain" only when nothing is extractable. Failed redactions — black boxes over live text — are how the Manafort and TSA leaks happened; verification is the step that catches them.
- Whole-document sanitization. Metadata (Info/XMP), annotations, bookmarks, embedded files, form values and JavaScript are stripped, fonts are subset, and the file is rebuilt from scratch — the layers where secrets survive a visual blackout.
- Don't trust, verify. PlainFile is open source (AGPL-3.0). The claim "your files never leave your device" is not a promise on a landing page — it is auditable code, and you can watch the Network tab while you work.
- Free stays free. No trial that expires, no subscription gate, no watermarks, no sign-up. The license makes that structurally hard to walk back.
What about Smallpdf, iLovePDF and the rest?
The large hosted platforms process files on their servers and advertise deletion after a retention window (Smallpdf states one hour). For a redaction task that means the unredacted original — the most sensitive version of the document — is exactly what gets uploaded. Local processing removes that question entirely, whichever local tool you pick.
The bottom line
Choose PrivacyScanPDF for breadth: dozens of utilities, PII scanning and provenance checks under one roof, if a subscription is acceptable. Choose PlainFile when the job is redaction itself and you want it done to a verifiable standard — free, open source, and with an automatic proof that the secrets are actually gone.
