PDF Bench
What "local processing" actually means
When we say PDF Bench runs locally, we mean your browser does all the PDF work right on your device. Your files are never sent to a server. That's a meaningful privacy benefit — but it's worth understanding exactly what it does and doesn't cover.
What it means for your files
- Your document never leaves your device. The browser reads, modifies, and reassembles the PDF without uploading anything.
- Once the app is loaded, you can keep working even without an internet connection.
- Sensitive documents stay on your own machine instead of passing through someone else's servers.
What it doesn't cover
- Local processing doesn't replace careful review — you still need to verify that redaction or sanitization worked correctly.
- The site itself still makes normal network requests (loading the page, analytics, ads). It's the PDF processing that stays local.
- Once you download a file and share it by email, upload it, or post it somewhere, local processing can't protect it anymore.
When it matters most
- You're working with sensitive business, legal, financial, or personal documents.
- Your organization restricts uploading documents to cloud services.
- You want a simpler privacy story: your files stay on your device, period.
