Clear the field for outline only.
Use DejaVu Sans for non-Latin scripts.
Set to match the original width. Drag if the line looks tight or loose.
Baseline to baseline, in points. Taken from the paragraph itself.
What happens when your wording is longer than the words it replaces.

Click a page to place. Use Select to move, drag a corner to resize, Del to remove, and the arrow keys to nudge half a point at a time (hold Shift for five). Double-click any text to retype it.

Edit text highlights the wording already in the document. Click a highlighted line to retype it, click your own edit to come back to it, or empty it to delete it. The line keeps the size, spacing, colour and baseline it had, so a replacement of about the same length lands on the same letters. It is rewritten in the closest matching font, so an unusual typeface will look similar rather than identical. Scanned pages have no text to edit.

Edit paragraph takes a whole block at once, and the text re-wraps as you type: write more and it flows onto new lines, write less and it pulls back up. Use it for rewriting; use Edit text for a quick fix to one line. The paragraph keeps its own line spacing and letter spacing, and a red dashed line warns when it has grown into whatever sits below it.

Highlight, comment and mark up a PDF

The annotate PDF tool gives you everything you need to mark up a document. Highlight the important lines, add a sticky note where something needs explaining, draw an arrow to point at a detail, or write a comment straight onto the page.

It is much clearer than writing feedback in a separate email. Your notes sit right next to what they are about, so whoever reads the file next knows exactly which part you meant. Everything is saved into the document and travels with it.

What you can mark up

Draw attention to the lines that matter in the colour you choose.
Sticky notes

Work through every page and save it all in one go.
