Where are my files?
PDF Studio never uploads your documents. Files you save are placed wherever
you choose in the Files app (iCloud Drive, On My iPhone, or any folder).
Why is the AI assistant unavailable on my device?
The AI runs entirely on-device via Apple Intelligence, which requires an
iPhone 15 Pro or newer on iOS 26 with Apple Intelligence enabled in
Settings. Every other feature works on all supported devices.
Why did a compressed or redacted page lose its form fields?
Compression and redaction rebuild pages as images (that is what makes
redaction permanent and files small). Text stays searchable via on-device
OCR, but interactive elements are flattened — the app warns before running
either tool.
