Sometimes you don't need to rewrite a PDF — you just need to drop a few words onto it. A date on a form, your name on a contract, a label on a diagram. In Falcon PDF, adding text is a distinct, lightweight action that places a new text box on top of the page without disturbing the original content.

When to add text vs. edit text

Pick the right mode and the job gets much easier:

  • Add Text — for placing brand-new text anywhere on the page. Ideal for forms, signatures lines, and notes.
  • Edit Text— for changing words that are already part of the document. If that's what you need, see how to edit a PDF.

Add a text box

  1. Open your PDF in Falcon PDF.
  2. Choose Add Text from the toolbar (the T icon).
  3. Tap or click where the text should start.
  4. Type your content. The box grows as you type.

Position and style it

  • Drag the box to fine-tune its position; use the alignment guides that appear.
  • Set font family, size, weight and color from the formatting bar.
  • Adjust opacity if you want the text to sit lightly over a colored background.
Match the form

For a natural look on printed forms, use a neutral font like Helvetica or Arial at 10–12 pt and black text. Turn off any background fill so only the letters show.

Fill flat (non-interactive) forms

Many PDFs look like forms but have no clickable fields — they're just lines and boxes drawn on the page. Adding text is the fastest way to complete them:

  1. Zoom in so you can place text precisely on each line.
  2. Add a separate text box for each field rather than one large block.
  3. Use consistent sizing so the finished form looks tidy.
Field typeRecommended approach
Single line (name, date)One small text box aligned to the line
CheckboxA short text box with an “X” or “✓”
Multi-line notesA single box with wrapping enabled

Tips for clean results

  • Group related boxes so you can move them together if the layout shifts.
  • Flatten on exportso recipients can't accidentally move your text.
  • If the file gets large after edits, run it through the compress tool before sharing.
Prefer marking up instead?

If your goal is feedback rather than filling in fields, highlights and comments may be a better fit. See how to annotate a PDF.

FAQ

Can I change the text later? Yes — text boxes stay editable until you flatten the document. Tap one to retype or restyle it.

Does added text print correctly? Yes. It becomes part of the page on export, so it prints exactly where you placed it. Get the app from the download page.
