Annotation Editor

Mark up screenshots
without leaving the app.

Arrows, shapes, text, numbered callouts, freehand drawing, and a redaction tool for sensitive info. Every tool has a single-key shortcut, and every mark stays editable after you place it. It lives in Markup mode inside Studio, so it works on recordings as well as screenshots.

Annotate · redact · editAn arrow is drawn, callouts number themselves, an address is redacted, then the arrow is picked back up with the pointer, moved and recoloured.

Every tool you need,
one key away.

D

Freehand drawing

Draw anything directly on your screenshot. Circle something important, underline text, sketch an arrow by hand. Three stroke widths available.

A

Arrows

Point at exactly what matters. Click the start point, drag to the end. Clean, straight arrows that make your point immediately clear.

S

Shapes

Rectangles, ellipses, diamonds, and lines. Outline a region, highlight a section, or frame an important element. All shapes are stroke-only so they don't obscure content.

T

Text labels

Click anywhere to add a text label. Type your note, pick a color, done. Useful for adding context, naming elements, or writing step numbers.

C

Numbered callouts

Auto-incrementing numbered markers. Click to place callout 1, 2, 3, and so on. Perfect for step-by-step instructions, labeling UI elements, or referencing specific areas.

X

Redaction

Drag over sensitive information to cover it. Solid block is the default and the safest; pixelate comes in fine, medium and heavy. Pixelation samples what is already painted underneath rather than the original image, so stacking a blur over a black box cannot put the hidden text back on screen.

V

Pointer

For when you want to look without drawing, and for picking marks back up. Click a mark to select it, drag to move it, drag a handle to resize it, recolour it from the row below, or delete it with Del.

P

Cursor stamp

Captures come through without the operating system cursor, which is usually what you want and occasionally not. Stamp one back in wherever it needs to be.

R

Crop

Arms a rect over the whole image and cuts nothing until you say so. Drag the sides or corners, watch the live pixel readout, then Apply. Thirds guides and a dimmed surround show what you are keeping, and it is undoable like everything else.

Nothing is
final until you save.

Most annotation tools bake a mark into the image the moment you let go of the mouse, which means fixing the second of five arrows costs you the other three. Here every mark is an object until you save.

Pick a mark back up

Press V, click the mark, and move it, resize it by its handles, recolour it, or delete it. Double-click a text label to fix a typo instead of redrawing it.

Stored in source pixels

Marks live in the original image's coordinates, so they stay exactly where you put them through a crop, an aspect ratio change, a window resize, or an export at a different scale.

Six colours and a palette

Six defaults that stand out on any background, plus your own saved solids and gradients. Stroke comes in three widths, and sizes are a fraction of the source, so a mark on a 4K capture matches one on 720p.

One undo stack

Ctrl+Z and Ctrl+Y step through annotations and crops together, so there is no separate history to reason about. Ctrl+C copies the result, Ctrl+S saves it, Ctrl+V pastes an image in to start from.
