Can I add text to a screenshot?

Yes. Select the Text tool, click anywhere on the screenshot, and type your label. You can adjust the font size, color, and background.

How do I blur sensitive information?

Select the Blur tool and drag over the area you want to hide. TrarrenShot applies a pixelated blur that cannot be reversed by the recipient.

Can I undo annotation changes?

Yes. Press ⌘Z to undo any annotation step. You can undo all the way back to the original screenshot.

Screenshot Annotation in TrarrenShot

TrarrenShot includes a full-featured annotation editor that opens automatically after every capture. No need to switch to a separate app — add arrows, callouts, text, and blur directly in TrarrenShot before sharing.

How to Annotate

Take a screenshot

Use any capture mode. The annotation editor opens automatically.

Select a tool

Click a tool in the toolbar or use its keyboard shortcut. The toolbar shows the currently active tool.

Draw on the screenshot

Click or drag to add your annotation. Hold ⇧ while drawing to constrain shapes to perfect squares or circles.

Adjust style and save

Use the style panel on the right to change color and line weight. Press ⌘S to save or ⌘C to copy.

Double-click any annotation after adding it to edit its text or style. All annotations are non-destructive until you save.

Privacy: Blur Redaction

The Blur tool applies a strong pixelation effect to hide sensitive data — passwords, personal information, credit card numbers, faces. The blur is permanent in the saved image and cannot be reversed.

Always save a separate un-annotated copy if you need the original screenshot without redactions.
