Add Text to PDF

Need to fill in a name on a form that has no fields, stamp “PAID” or “COPY” on an invoice, or add a note to a scanned page? Type the text, choose where it goes and how it looks, and download the edited PDF. Text in Latin scripts is written as real, searchable PDF text; other scripts such as Korean are placed as a sharp image. Your file stays in your browser.

How to use this tool

1. Choose the PDF and type the text — press Enter for a new line.
2. Pick the page or pages, and a position: a corner, the middle, or exact X and Y in millimetres from the top-left corner.
3. Choose the font, size, colour and opacity; set a wrap width to break long text into lines.
4. Download the PDF with your text added.

Formula

Positions: X and Y in mm × 2.835 = PDF points, measured from the top-left corner of the page as you see it. Line height = 1.25 × font size; wrapped lines break at spaces when their width would exceed the wrap width.

Preset positions keep a 15 mm margin. Opacity below 100% makes the text see-through, which suits stamps like DRAFT or COPY.

Example

To write a name into a printed form box that starts 45 mm from the left and 62 mm from the top, choose Custom, X = 45, Y = 62 and size 11 pt. The text’s top-left corner lands at 45 × 2.835 ≈ 127.6 pt from the left edge, and the first baseline sits about one cap height below the 62 mm line.

Searchable text or an image?

The 14 standard PDF fonts (Helvetica, Times and Courier families) cover Western European letters and common symbols, and text drawn with them can be searched and copied. For Korean, Chinese, Japanese, Cyrillic or emoji the tool draws the text with your device’s fonts into a transparent image at four times the resolution, which looks crisp on screen and in print but is not searchable. For full editing, use a desktop PDF editor.
