FAQ
Is the Google blocking feature really free?
Yes! Blocking PDFs from Google indexing is completely free and unlimited. No account required. It works locally by adding X-Robots-Tag headers.
How does the Google blocking work?
The plugin adds X-Robots-Tag: noindex headers to your PDF files via .htaccess rules in your uploads directory, telling search engines not to index them. This is the same method recommended by Google.
What happens to my files during compression?
Your PDF is uploaded to our secure Nordic servers in Finland, compressed using Ghostscript, and returned to your WordPress site. A deletion certificate is generated proving the original was deleted from our servers.
Is this GDPR compliant?
Yes. All file processing happens on our secure servers in Finland, within the Nordic region. We don’t store your files longer than necessary for processing, and we provide deletion certificates as proof.
What data is sent to external servers?
Only when you use premium features (compress, watermark, leak scan). The free blocking feature works entirely locally. See the External Service section for details.
How do I get more compressions?
Upgrade to a PDF.dk Pro subscription for unlimited compressions and watermarks at pdf.dk/priser.
