Question 2

Do my files leave my device?

Accepted Answer

No! Except for the AI features (Image to Text OCR and Image Translation, which safely process images via the secure Gemini API routes and do not store them), all PDF modifications, conversions, cropping, calculations, and compression are completed 100% in-memory in your browser. Your private files never touch our servers.

Never. PDFscaler is entirely browser-based, meaning it operates securely on Google Chrome, Safari, Firefox, Edge, and mobile browser sessions without requiring extensions or software installs.

Question 4

Do the tools work on mobile?

Accepted Answer

Yes, PDFscaler is fully responsive and custom-optimized to support touch screens on all iOS and Android phones and tablets, allowing you to convert files on the go.

Question 5

Is my data tracked?

Accepted Answer

We respect privacy first. We do not track, log, or read your file contents. There are no user accounts, signup sheets, or tracking pixels reading your documents.
