Page tools

Use the page toolbar to navigate, rotate, delete, zoom, or fit a page. Undo and redo are available from the editor navigation.

Change font, size or colour

In the edit dialog, open Optional formatting adjustments. Choose a font, type any size from 1 to 500 pt, or set bold, italic and colour. Changing any of these switches off Continue current formatting, so your choices are used when you select Apply. Tick the box again to return to the original style.

Edit a whole paragraph

1. Choose Edit text and tap any word in the paragraph.
2. Select Edit whole paragraph. The full paragraph opens in an edit box.
3. Type freely and press Enter for a new line. Text wraps automatically to the paragraph width, like in Word.
4. Select Add. The paragraph becomes a box you can drag, or make wider or narrower with its yellow corner handle.

PDF text below a paragraph can't move down by itself. If your paragraph gets longer, open the next paragraph the same way, select Add without changing it, and drag it down to make room. Use Restore original paragraph to undo all changes to a paragraph.

Add images, logos and signatures

Select Add image and choose a JPG or PNG file. Drag the image to move it, and pull the yellow corner handle to resize it. Select an image and press Delete to remove it. On a computer, arrow keys nudge the selected image or text box.

Add text, highlight and draw

• Add text: choose Add text, tap where the text should go, and type it. Press Enter for new lines. Drag the box to move it, or pull its yellow corner to set a width so the text wraps.
• Highlight: choose Highlight, pick a color in the bar above the page, and drag across the area to mark.
• Draw / Sign: choose Draw / Sign, pick a pen color and thickness in the bar above the page, and drag to sign your name or sketch freehand, for example to circle or underline content. For a neat signature, zoom in first, and use black or dark blue at 2–3 px. Tip: the white pen can cover small marks. Your color choices are remembered.
• Copy format: choose Copy format, tap text with the style you want, then tap the text to restyle.

Download as PDF or Word

Download PDF keeps the original pages and adds your changes as real, selectable text. Text with characters that standard PDF fonts can't show, such as ₹, Indian-language scripts or emoji, is added as an image so it still looks correct. Download Word creates a .docx file with the page as a background and the text in editable text boxes.
