Questions and answers
How do I add text to a PDF?
Choose “Text”, click on the page and type. Size and colour are in the top bar; double-click the text to change it.
How do I redact data in a PDF?
The “Redact” tool removes data under the box for good: on save the page becomes an image, so hidden text cannot be copied or found.
Are non-Latin letters kept?
Yes. Text is written with a font that supports Cyrillic and Latin, and stays searchable in the saved PDF.
Can I undo a change?
Yes — Ctrl+Z undoes the last action, Ctrl+Y redoes it.
