## Steps

2. **Review your settings** — Choose the options available for this conversion.
3. **Download the masked PDF** — Keep the result in your workspace or download it immediately.

## Common questions

### Is this PDF to masked PDF converter free?

Yes. The local converter is available without an account or per-file charge.

### Are my files uploaded?

No. Supported conversions run locally on your device using browser APIs and WebAssembly.

### Will complex formatting look identical?

Text and document structure are preserved where possible. PDFs use layout-aware reconstruction and automatic local OCR for scanned pages, though very unusual fonts or visual layouts can still differ.
