How to Annotate a Screenshot on iPhone (iOS)

Add arrows, text, and highlights to a screenshot using built-in tools.

Last verified: February 21, 2026

The iOS Markup editor opens as soon as you tap the screenshot thumbnail in the bottom-left corner, presenting a full toolbar of drawing tools — pencil, pen, marker, eraser, ruler, and a shapes insert menu — along with a colour picker and opacity slider. The editor enters Full Screen mode automatically in landscape orientation, giving you more working space for detailed annotations on tablets. Annotated screenshots save back to the Photos library at full resolution, and you can share the marked-up version directly from within the editor.

Quick Steps

Follow in order for the fastest result.

  1. 1Take a screenshot and tap the preview thumbnail. Use the Markup toolbar to draw, add text, and insert arrows or shapes.
  2. 2Add callout arrows and text labels to draw clear attention to specific areas.
  3. 3Save or share the annotated image using the Done / Share button in the editor.
