Frequently asked questions
Can I directly change the PDF's existing text?
No. This focused tool adds new text boxes over the PDF; it does not rewrite original PDF text objects.
Is my PDF uploaded?
No. Loading, text editing and export happen inside your browser.
Can I add multiple text boxes?
Yes. Text remains selected after each entry, so click another empty area to add the next box.
Can I format the text?
Yes. You can change the standard PDF font, font size and text color.
Can I write on multiple pages?
Yes. Use the page thumbnails and add separate text elements to any page.
Does it support every Unicode character?
Standard PDF fonts support English and common Western European characters. Unsupported characters are replaced safely rather than causing export to fail.
