Editing existing text

Adding new text is free. Editing original text requires analyzing the text layer, managing embedded fonts, and for scanned documents, OCR. With Premium, you can import the text layer or use the Italian local OCR to convert a scan into editable blocks. In complex layouts, a visual check is always recommended.
