Is my PDF uploaded to a server?

No. The entire PDF Health Check process runs client-side in your web browser. No document files, content, or metadata are ever uploaded to external servers, protecting your privacy.

How is the Health Score calculated?

The score (0-100) is evaluated based on page density (size per page), text accessibility (searchable text vs scanned images), and structure ratios (metadata and image counts).

Can I check password-protected PDFs?

Yes. If a file is encrypted, the check will identify it as locked. You can enter the password locally to decrypt it in-memory and proceed with the full health diagnostics.

What do the recommendations help with?

Recommendations point you to the appropriate free tools (like Compress PDF, Extract Images, etc.) to optimize the specific issues discovered in your document.

Files never leave your device. Processing happens locally in your browser.
