Frequently Asked Questions
Can recipients delete or modify the flattened editorial markup?
No. Annotations lose their editable property inspector attributes and become permanent parts of the document imagery.
Are confidential research memos or architectural plans uploaded?
No. All processing runs 100% locally in browser memory via WebAssembly. Your project plans remain confidential.
Will text beneath highlighted sections remain readable and sharp?
Yes. PDFZento maintains correct alpha transparency blending so highlighted text remains crisp and legible.
