How to add text to a screenshot on iPhone

To add useful text to a screenshot on iPhone, write one short label that supplies missing context, place it where it does not cover important content, and check that it stays readable at social-feed size. ScreenEdit lets you add the text, frame the complete screenshot, and export the result as a PNG.

Write the label before styling it

Start with what the text needs to communicate. A useful label identifies a point, a sequence, or a comparison that the screenshot cannot explain on its own.

Good labels are specific:

• “Before” and “After” for a comparison
• “The part I missed” beside an arrow
• “Step 1” and “Step 2” for a short sequence
• A brief title that makes the screenshot understandable outside the post copy

If the label repeats visible text from the screenshot, it probably is not needed.

Keep it short enough to scan

Social images are often seen as previews first. A long paragraph becomes small, wraps across the frame, and competes with the screenshot.

Aim for one line when possible. If the idea needs several sentences, put the explanation in the post and let the image carry only the key phrase.

Put text in the frame, not over the subject

The cleanest place for a label is often the space around the screenshot. Scale the complete screenshot inside a 16:9, 5:3, 4:3, or 1:1 frame, then use the surrounding canvas for the text.

This keeps the original content unobstructed and gives the label a stable background. If the label must sit over the screenshot, place it on an area with little detail and check its contrast carefully.

Make the text easy to read

Use a text colour that clearly separates from the background. When the screenshot or frame is busy, a simple filled shape behind the label can provide enough contrast.

Keep the style consistent across one image. Several sizes, colours, and alignments can make even a short label feel disorganised.

Pair text with an arrow when location matters

Text explains what the viewer should notice. An arrow explains where to find it. Use both when the label refers to a small or easily missed detail.

Place the label first, then draw the arrow from the label toward the subject. Keep the arrow short and avoid crossing other text in the screenshot.

Label combined screenshots consistently

When two or more screenshots share one frame, use the same label treatment for each image. Matching “Before” and “After” labels are clearer than two unrelated styles.

Align the labels to the same edge, give them the same visual weight, and make the reading order obvious.

Export and preview

After adding the text:

1. Check the image at a small size.
2. Confirm that the label is readable without zooming.
3. Make sure the complete screenshot content you need is still present.
4. Export the framed image as a PNG.
5. Inspect the attached image in X or Threads before publishing.

Social platforms control their own preview treatments, so keep essential text away from the frame edge and verify the final post rather than relying on one fixed display assumption.
