After capturing an image, tap the floating thumbnail preview to access Apple’s Markup tools for cropping, drawing, and adding text immediately.
Knowing how to edit a screenshot on iPhone is a core skill for anyone who shares phone screens, documents workflows, or just marks up a map before sending it to friends. The built-in Markup editor puts cropping, annotation, and text tools just one tap away — no third-party app needed.
The Standard Way to Edit a Screenshot
The quickest route goes through the thumbnail preview that appears right after you capture one. On a Face ID iPhone, press the Side button and the Volume Up button simultaneously. On a Touch ID iPhone, press the Home button and the Side (or Top) button together. Tap the floating thumbnail in the lower-left corner before it disappears to open the editing screen.
Once inside the editor, use the Markup toolbar along the bottom to annotate. When you are finished, tap Done to save the edited screenshot to your Photos library.
How to Edit a Screenshot on iPhone: Tools That Actually Save Time
The Markup editor packs surprising utility into one clean interface. The table below breaks down each tool and how to use it effectively.
| Tool | What It Lets You Do | Pro Tip |
|---|---|---|
| Crop | Trim edges by dragging corner handles. | Tap the aspect-ratio icon to keep dimensions square or locked. |
| Draw (Pen) | Sketch or highlight with your finger. | Hold your finger still at the end of a line to turn it into a perfect straight line. |
| Text | Add a text box with keyboard input. | Tap the text box to change font, size, and alignment. |
| Signature | Insert a saved signature or create a new one. | Rotate your iPhone to landscape for a larger drawing area when creating a new signature. |
| Magnifier | Enlarge a specific area of the image. | Drag the blue dot to control the zoom level and size of the magnified circle. |
| Shapes | Add arrows, circles, squares, or speech bubbles. | Tap a shape to change line thickness, fill color, and opacity. |
| Color & Opacity | Change the color and transparency of your annotations. | Use the eyedropper to sample an exact color from the screenshot itself. |
How to Crop or Rotate a Screenshot
Cropping is handled right inside the Markup interface. After tapping the thumbnail, drag the corner or edge handles inward to trim the image. You can also tap the rotate icon (the square with a curved arrow) to turn the image 90 degrees. The greyed-out area outside the crop boundary disappears permanently once you tap Done.
If you make a mistake, tap the Undo arrow in the toolbar before saving. You cannot undo a crop after tapping Done, so take a moment to confirm the framing first.
What Tools Are Available in the Markup Editor?
Beyond the basics, the Markup toolbar includes a few power-user options that are easy to miss. The Lasso tool lets you select a drawn element and move it or resize it without affecting the rest of the image. The Ruler tool helps draw perfectly straight horizontal or vertical lines, and it snaps to 45-degree angles as you rotate it with two fingers. These extras make the editor genuinely useful for quick diagrams or layout markups, not just casual doodles.
The iOS 26 Full-Screen Preview Change
In iOS 26, Apple changed how the screenshot preview behaves. Instead of a small floating thumbnail in the corner, the screenshot opens in a full-screen preview by default. That gives you more room to review the image before editing, but it also adds an extra tap compared to the older thumbnail workflow. If you prefer the classic thumbnail behavior, you can switch it back. MacRumors explains how to turn off full-screen screenshot previews inside the new Settings > General > Screen Capture menu.
How to Edit a Screenshot on iPhone: Choosing Your Editing Path
Not every editing session starts with a fresh capture. The table below shows the three ways to reach the Markup tools, depending on your situation.
| Method | Best For | How to Start |
|---|---|---|
| Thumbnail Preview | Fastest editing immediately after capture. | Tap the floating thumbnail in the bottom-left corner. |
| Photos App | Editing a screenshot taken minutes or days earlier. | Open Photos, tap the screenshot, tap Edit, then tap the Markup icon (pen tip). |
| Full-Page Capture | Saving an entire Safari webpage or supported document. | After capture, tap the thumbnail, then tap Full Page at the top. |
What Happens After You Tap “Done”?
Tapping Done saves the edited screenshot as a new image in the Photos app. The original, unedited screenshot also remains in your library, so you always have a backup. If you tapped Done by accident, you can open the image in Photos, tap Edit, and then tap Revert to restore the unmarked version.
Final Workflow Checklist
- Capture the screenshot using the correct hardware buttons for your iPhone model.
- Tap the thumbnail preview immediately before it disappears.
- Use the Markup tools to crop, annotate, draw, or add text.
- Tap Done to save the final image to Photos.
- (iOS 26 only) Adjust the preview style in Settings > General > Screen Capture if you prefer the old thumbnail overlay.
